## Detailed Description

type definitions for the dcmdata module

## Enumeration Type Documentation

## ◆ E_EncodingType

enum E_EncodingType

encoding type for sequences and sequence items

Enumerator
EET_ExplicitLength | defined length
EET_UndefinedLength | undefined length

## ◆ E_FileReadMode

enum E_FileReadMode

mode for file reading

Enumerator
ERM_autoDetect | auto detect: fileformat or dataset
ERM_dataset | read as dataset (assume no meta header present)
ERM_fileOnly | read file format only, refuse if no meta-header
ERM_metaOnly | read meta-header only, do not read the dataset

## ◆ E_FileWriteMode

enum E_FileWriteMode

mode for file writing

Enumerator
EWM_fileformat | write as fileformat (update only missing information, this is the old behavior)
EWM_dataset | write as dataset (without meta header)
EWM_updateMeta | write as fileformat and update required information (e.g. SOP Class/Instance UID)
EWM_createNewMeta | write as fileformat and create new meta header (do not retain existing information except SOP Class/Instance UID)
EWM_dontUpdateMeta | write as fileformat but don't update the meta header (please be careful!)

## ◆ E_GrpLenEncoding

enum E_GrpLenEncoding

handling of group length elements when reading/writing a dataset

Enumerator
EGL_noChange | no change of group length values, WARNING: DO NOT USE THIS VALUE FOR WRITE OPERATIONS
EGL_withoutGL | remove group length tags
EGL_withGL | add group length tags for every group
EGL_recalcGL | recalculate values for existing group length tags

## ◆ E_PaddingEncoding

enum E_PaddingEncoding

handling of dataset trailing padding

Enumerator
EPD_noChange | no change of padding tags
EPD_withoutPadding | remove all padding tags
EPD_withPadding | add padding tags

## ◆ E_SearchMode

enum E_SearchMode

search mode for hierarchical search operations

Enumerator
ESM_fromHere | start search from current object
ESM_fromStackTop | start search from object pointed to by stack top
ESM_afterStackTop | start search from object following the object pointed to by stack top

## ◆ E_TransferState

enum E_TransferState

object state during transfer (read/write) operations

Enumerator
ERW_init | object prepared for transfer, no data transferred yet
ERW_ready | object transfer completed
ERW_inWork | object transfer in progress
ERW_notInitialized | object not prepared for transfer operation
