Detailed Description

template<class StructHeader>
class ChimeraTK::MappedStruct< StructHeader >

Provides interface to a struct that is mapped onto a 1D array of ValType StructHeader must be derived from OpaqueStructHeader.

Variable-length structs are supported, as long as they do not grow beyond the size of the given 1D array.

NOTE: MappedStruct concept is discouraged. Use DataConsistencyGroup of struct members instead if possible. It is still required for MappedImage.

Member Enumeration Documentation

InitData

template<class StructHeader >

enum ChimeraTK::MappedStruct::InitData

strong

Enumerator
Yes
No

Constructor & Destructor Documentation

MappedStruct()

template<class StructHeader >

ChimeraTK::MappedStruct< StructHeader >::MappedStruct ( ChimeraTK::OneDRegisterAccessor< unsigned char > &  accToData, InitData  doInitData = InitData::No  )

explicit

This keeps a reference to given OneDRegisterAccessor.

If its underlying vector is swapped out, the MappedStruct stays valid only if the swapped-in vector was also setup as MappedStruct.

Member Function Documentation

capacity()

template<class StructHeader >

size_t ChimeraTK::MappedStruct< StructHeader >::capacity

capacity of used container

Definition at line 196 of file MappedImage.h.

data()

template<class StructHeader >

unsigned char * ChimeraTK::MappedStruct< StructHeader >::data

returns pointer to data for header and struct content.

The returned pointer stays valid until write() or read() is called for the underlying accessor.

Definition at line 191 of file MappedImage.h.

Here is the caller graph for this function:

header()

template<class StructHeader >

StructHeader* ChimeraTK::MappedStruct< StructHeader >::header ( )

inline

returns header, e.g. for setting meta data

Definition at line 54 of file MappedImage.h.

Here is the caller graph for this function:

initData()

template<class StructHeader >

void ChimeraTK::MappedStruct< StructHeader >::initData

default initialize header and zero out data that follows

Definition at line 202 of file MappedImage.h.

size()

template<class StructHeader >

size_t ChimeraTK::MappedStruct< StructHeader >::size ( ) const

inline

currently used size

Definition at line 52 of file MappedImage.h.
