Detailed Description

Lightweight view over a slave's TxPDO image.

Provides presence checks and typed accessors to values mapped into the device TxPDO. Lifetime note: this is a non-owning view, valid as long as the underlying process image buffer remains alive and unmoved.

Constructor & Destructor Documentation

TxView()

CiA402::TxView::TxView ( const uint8_t * base, const std::unordered_map< TxField, FieldInfo > * map )

inline

Construct a view.

Parameters

base	Pointer to the beginning of the raw TxPDO buffer for a slave.
map	Pointer to the field map describing where each entry is.

Member Function Documentation

get()

template<typename T>

T CiA402::TxView::get ( TxField f, T fallback = {} ) const

inline

Read a field from the TxPDO image with a typed accessor.

Supports any trivially copyable type whose size matches the mapped field (commonly 8/16/32-bit integers or IEEE-754 REALs coming from the drive). If the field is not present or the size does not match, the fallback is returned.

has()

bool CiA402::TxView::has ( TxField f ) const

inline

Check if a given field is available in the current mapping.
