inline

Member Function Documentation

◆ precomputeFrameInfo()

void ChannelPort::TranslationInfo::precomputeFrameInfo ( )

Precompute and optimize the copy operations for translating frames.

Definition at line 264 of file Ports.cpp.

◆ requireTranslationSupported()

void ChannelPort::TranslationInfo::requireTranslationSupported ( ) const

Throw if this window cannot be translated by the runtime translator (e.g.

uses serial/bulk list encoding which is not yet supported).

Member Data Documentation

◆ frameBytes

size_t esi::ChannelPort::TranslationInfo::frameBytes = 0

Number of bytes per wire frame (from the lowered type's bit width).

Definition at line 292 of file Ports.h.

◆ frames

std::vector<FrameInfo> esi::ChannelPort::TranslationInfo::frames

Precomputed information about each frame.

Definition at line 287 of file Ports.h.

◆ hasListField

bool esi::ChannelPort::TranslationInfo::hasListField = false

True if the window contains a list field (variable-size message).

Definition at line 294 of file Ports.h.

◆ intoTypeBytes

size_t esi::ChannelPort::TranslationInfo::intoTypeBytes = 0

Size of the 'into' type in bytes (for fixed-size types).

For types with lists, this is the size of the fixed header portion.

Definition at line 290 of file Ports.h.

◆ windowType

const WindowType* esi::ChannelPort::TranslationInfo::windowType

The window type being translated.

Definition at line 244 of file Ports.h.
