N ax |
N ast |
C Node | The base abstract node which determines the interface and required methods for all derived concrete nodes which comprise a valid AST
C Statement | Abstract (pure-virtual) AST nodes
C Expression | Expressions are comprised of full or potentially partial parts of a full statement that may not necessary make up an entire valid statement on their own. For example, while a Binary Operator such as "3 + 5;"" is a valid statement on its own, the full statement "3 + 5 + 6;" must be broken down into two expressions which together form the statement as well as determining precedence
C Variable | Variables are a base type for Locals, Attributes and ExternalVariables. Unlike other abstract types, they also consolidate data for the derived types
C ValueBase | ValueBases are a base class for anything that holds a value (literal). Derived classes store the actual typed values
C StatementList | Concrete AST nodes
C Block | A Block node represents a scoped list of statements. It may comprise of 0 or more statements, and specifically indicates that a new scope is activated, typically represented by curly braces. Note that a block does not alway have to be encapsulated by curly braces, but always represents a new scope
C Tree | A Tree is the highest concrete (non-abstract) node in the entire AX AST hierarchy. It represents an entire conversion of a valid AX string
C CommaOperator |
C Loop | Loops represent for, while and do-while loop constructs. These all consist of a condition - evaluated to determine if loop iteration should continue, and a body which is the logic to be repeated. For loops also have initial statements which are evaluated prior to loop execution (at loop scope) and commonly used to set up iterators, and iteration expressions which are evaluated between iterations after the body and before the condition. Both conditions and initial statements can be declarations or expressions, so are Statements, and iteration expressions can consist of multiple expressions. The loop body is a Block defining its own scope (encapsulated by initial statement scope for for-loops)
C ConditionalStatement | ConditionalStatements represents all combinations of 'if', 'else' and 'else if' syntax and semantics. A single ConditionalStatement only ever represents up to two branches; an 'if' (true) and an optional 'else' (false). ConditionalStatements are nested within the second 'else' branch to support 'else if' logic. As well as both 'if' and 'else' branches, a ConditionalStatement also holds an Expression related to its primary condition
C BinaryOperator | A BinaryOperator represents a single binary operation between a left hand side (LHS) and right hand side (RHS) expression. The operation type is stored as a tokens::OperatorToken enumerated type on the node. AX grammar guarantees that this token will only ever be a valid binary operator token type when initialized by the parser
C TernaryOperator | A TernaryOperator represents a ternary (conditional) expression 'a ? b : c' which evaluates to 'b' if 'a' is true and 'c' if 'a' is false. Requires 'b' and 'c' to be convertibly typed expressions, or both void. The 'true' expression ('b') is optional with the conditional expression 'a' returned if it evaluates to true, otherwise returning 'c'. Note that 'a' will only be evaluated once in this case
C AssignExpression | AssignExpressions represents a similar object construction to a BinaryOperator. AssignExpressions can be chained together and are thus derived as Expressions rather than Statements
C Crement | A Crement node represents a single increment '++' and decrement '–' operation. As well as it's crement type, it also stores whether the semantics constructed a post or pre-crement i.e. ++a or a++
C UnaryOperator | A UnaryOperator represents a single unary operation on an expression. The operation type is stored as a tokens::OperatorToken enumerated type on the node. AX grammar guarantees that this token will only every be a valid unary operator token type when initialized by the parser
C Cast | Cast nodes represent the conversion of an underlying expression to a target type. Cast nodes are typically constructed from functional notation and do not represent construction of the target type, rather a type-casted conversion
C FunctionCall | FunctionCalls represent a single call to a function and any provided arguments. The argument list can be empty. The function name is expected to exist in the AX function registry
C Keyword | Keywords represent keyword statements defining changes in execution. These include those that define changes in loop execution such as break and continue, as well as return statements
C ArrayUnpack | ArrayUnpack represent indexing operations into AX container types, primarily vectors and matrices indexed by the square brackets [] syntax. Multiple levels of indirection (multiple components) can be specified but current construction is limited to either a single or double component lookup. Providing two components infers a matrix indexing operation
C ArrayPack | ArrayPacks represent temporary container creations of arbitrary sizes, typically generated through the use of curly braces {}
C Attribute | Attributes represent any access to a primitive value, typically associated with the '@' symbol syntax. Note that the AST does not store any additional information on the given attribute other than its name and type, which together form a unique Attribute identifier known as the Attribute 'token'. A 'primitive value' in this instance refers to a value on an OpenVDB Volume or OpenVDB Points tree
C ExternalVariable | ExternalVariable represent any access to external (custom) data, typically associated with the '$' symbol syntax. Note that the AST does not store any additional information on the given external other than its name and type, which together form a unique external identifier known as the ExternalVariable 'token'. This token is used by the compiler to map user provided values to these external values
C Local | Local AST nodes represent a single accesses to a local variable. The only store the name of the variable being accessed
C DeclareLocal | DeclareLocal AST nodes symbolize a single type declaration of a local variable. These store the local variables that They also however store its specified type. These have the important distinction of representing the initial creation and allocation of a variable, in comparison to a Local node which only represents access
C Value | A Value (literal) AST node holds either literal text or absolute value information on all numerical, string and boolean constants. A single instance of a Value is templated on the requested scalar, boolean or string type. If scalar or boolean value is constructed from a string (as typically is the case in the parser), the value is automatically converted to its numerical representation. If this fails, the original text is stored instead
C Value< std::string > | Specialization of Values for strings
C VisitNodeType |
C Visitor | The Visitor class uses the Curiously Recursive Template Pattern (CRTP) to provide a customizable interface intended to be used by clients wishing to perform custom operations over an AX Abstract Syntax Tree (AST). By default the Visitor implements simple traversal of all nodes, ensuring that each node on a well formed AST is visited at least once. By deriving from the Visitor, users are able to customize this default behavior and further manually override specific node behavior to their needs. The function options at the top of visitor can be overridden using CRTP to control the prior default behavior, with the ability to override the traverse() and visit() methods for the latter more granular control

N codegen_internal |
C ComputeGenerator | Visitor object which will generate llvm IR for a syntax tree. This provides the majority of the code generation functionality except for attribute access. This design allows for custom geometry to define their IR implementations for these accesses by deriving and extending this generator with ast::Attribute handling (see PointComputeGenerator.h and VolumeComputeGenerator.h for examples)
C PointComputeGenerator | Visitor object which will generate llvm IR for a syntax tree which has been generated from AX that targets point grids. The IR will represent 2 functions : one that executes over single points and one that executes over a collection of points. This is primarily used by the Compiler class
C PointLeafLocalData | Various functions can request the use and initialization of point data from within the kernel that does not use the standard attribute handle methods. This data can then be accessed after execution to perform post-processes such as adding new groups, adding new string attributes or updating positions
C VolumeComputeGenerator | Visitor object which will generate llvm IR for a syntax tree which has been generated from AX that targets volumes. The IR will represent a single function. It is mainly used by the Compiler class
C Codec |
C ComputeKernel | The function definition and signature which is built by the ComputeGenerator
C ConstantFolder | Constant folding support structure
C ConstantFolder< SignatureT, 0 > |
C FunctionRegistry | The function registry which is used for function code generation. Each time a function is visited within the AST, its identifier is used as a key into this registry for the corresponding function retrieval and execution. Functions can be inserted into the registry using insert() with a given identifier and pointer
C RegisteredFunction | An object to represent a registered function, storing its constructor, a pointer to the function definition and whether it should only be available internally (i.e. to a developer, not a user)
C ArgType | Object to array conversion methods to allow functions to return vector types. These containers provided an interface for automatic conversion of C++ objects to LLVM types as array types
C LLVMType< ArgType< T, S > > |
C TypeToSymbol | Type to symbol conversions - these characters are used to build each functions unique signature. They differ from standard AX or LLVM syntax to be as short as possible i.e. vec4d, [4 x double] = d4

C ArgumentIterator< SignatureT, 0 > |
C ArgInfo | Metadata associated with a function argument or return value
C ArgInfoVector | Container of ArgInfos. This class makes up part of the Function API for querying signature information
C NativeArguments | Wrapper struct to represent "native" function arguments; that is, the set of Value type that the AX grammar supports. NativeArguments have two benefits; they support casting and implicit function matching through FunctionGroups and can be used directly in IR generators (to leverage the AX Value API). Functions can still be generated and called with "non-native" arguments, but in these cases FunctionGroup::execute must result in an explicit signature match
C Arguments | Arbitrary, potentially "non-native" arguments. This wrapper struct can be used when generating function which cannot be called from AX itself (e.g. VDB accessor functions or Volume/Point kernels etc). They do not support implicit function signature matching or casting
C Function | The base/abstract representation of an AX function. Derived classes must implement the Function::types call to describe their signature
C SRetFunction | Templated interface class for SRET functions. This struct provides the interface for functions that wish to return arrays (vectors or matrices) by internally remapping the first argument for the user. As far as LLVM and any bindings are concerned, the function signature remains unchanged - however the first argument becomes "invisible" to the user and is instead allocated by LLVM before the function is executed. Importantly, the argument has no impact on the user facing AX signature and doesn't affect declaration selection
C CFunctionBase | The base class for all C bindings
C CFunction | Represents a concrete C function binding
C IRFunctionBase | The base/abstract definition for an IR function
C IRFunction | Represents a concrete IR function
C CFunctionSRet | Represents a concrete C function binding with the first argument as its return type
C IRFunctionSRet | Represents a concrete IR function with the first argument as its return type
C FunctionGroup | A group of functions which all have the same name but different signatures. For example: float abs(float) double abs(double) As well as serving as a way of grouping common functions, this class provides an API for selecting the best possible function signature, should a match exist, against a provided set of argument types
C FunctionBuilder | Builder pattern framework to allow easy and valid construction of AX functions. There are a number of complex tasks which may need to be performed during construction of C or IR function which are delegated to this builder, whilst ensuring that the constructed functions are guaranteed to be valid

C AliasTypeMap | Alias mapping between two types, a frontend type T1 and a backend type T2. This class is the intended interface for binding objects which implement supported backend AX/IR types to this given backend type. More specifically, it's current and expected usage is limited to objects which hold a single member of a supported backend type and implements a StandardLayoutType as defined by the standard. Fundamentally, T1->T2 mapping should be supported by reinterpret_cast<> as defined by the type aliasing rules

C VolumeKernelBuffer | The second volume kernel, responsible for providing the core layer of SIMD optimisations by invoking this kernel across a range of values
C VolumeKernelNode | The third volume kernel, providing an agnostic way to modify a single tile value without passing through the buffer states. Note that this kernel is mainly utility and one of the value kernels should almost always be preferred
C AttributeBindings | This class wraps an interface for a map of attribute bindings. These map attributes in AX code to context data. These mappings are one-to-one i.e. each AX name can only map to one data name, however each name can appear as either an AX name or data name or both, i.e. the following sets of bindings are valid: axname: a -> dataname: a axname: b -> dataname: c or axname: a -> dataname: b axname: b -> dataname: a
C AttributeRegistry | This class stores a list of access names, types and their dependency connections

C index_sequence | Re-implementation of C++17's index_sequence and the helper alias make_index_sequence. This was introduced to fix an issue with clang's builtin implementation which treats template specializations of builtin templates differently when a subsequent parameter is dependent. The result is a resolution failure during partial specialization selection. For example, the following will fail to specialize:
