Member Function Documentation

AddFields()

void OMFFormat::Segment::Record::AddFields ( Dumper::Dumper & dump, Dumper::Region & region, const OMFFormat & omf, const Segment & segment, unsigned index, offset_t file_offset, offset_t address ) const

virtual

Adds any further fields to the file region that encompasses this record.

Reimplemented in Apple::OMFFormat::Segment::ValueRecord, Apple::OMFFormat::Segment::RelocationRecord, Apple::OMFFormat::Segment::IntersegmentRelocationRecord, Apple::OMFFormat::Segment::StringRecord, Apple::OMFFormat::Segment::LabelRecord, Apple::OMFFormat::Segment::LabelExpressionRecord, Apple::OMFFormat::Segment::RangeRecord, Apple::OMFFormat::Segment::ExpressionRecord, Apple::OMFFormat::Segment::RelativeExpressionRecord, Apple::OMFFormat::Segment::EntryRecord, and Apple::OMFFormat::Segment::SuperCompactRecord.

AddSignals()

void OMFFormat::Segment::Record::AddSignals ( Dumper::Block & block, offset_t current_segment_offset ) const

virtual

If this is a relocation record, add the relocation signals to the block.

Reimplemented in Apple::OMFFormat::Segment::RelocationRecord, and Apple::OMFFormat::Segment::SuperCompactRecord.

Dump()

void OMFFormat::Segment::Record::Dump ( Dumper::Dumper & dump, const OMFFormat & omf, const Segment & segment, unsigned index, offset_t file_offset, offset_t address ) const

virtual

Displays information pertaining to this record.

Parameters

dump	The dumper interface
omf	The entire file
segment	The segment the record is part of
index	0-based index of the record within the segment
file_offset	Full file offset, including segment start offset, that this record starts at
address	The current memory pointer when this record is interpreted

Reimplemented in Apple::OMFFormat::Segment::DataRecord, and Apple::OMFFormat::Segment::SuperCompactRecord.

GetLength()

offset_t OMFFormat::Segment::Record::GetLength ( const Segment & segment ) const

virtual

Returns the size of the record, as stored in the file.

Parameters

segment

The segment the record is part of

Reimplemented in Apple::OMFFormat::Segment::DataRecord, Apple::OMFFormat::Segment::ValueRecord, Apple::OMFFormat::Segment::RelocationRecord, Apple::OMFFormat::Segment::IntersegmentRelocationRecord, Apple::OMFFormat::Segment::StringRecord, Apple::OMFFormat::Segment::LabelRecord, Apple::OMFFormat::Segment::LabelExpressionRecord, Apple::OMFFormat::Segment::RangeRecord, Apple::OMFFormat::Segment::ExpressionRecord, Apple::OMFFormat::Segment::RelativeExpressionRecord, Apple::OMFFormat::Segment::EntryRecord, and Apple::OMFFormat::Segment::SuperCompactRecord.

GetMemoryLength()

offset_t OMFFormat::Segment::Record::GetMemoryLength ( const Segment & segment, offset_t current_address ) const

virtual

Returns the amount of memory the record occupies when loaded into memory. Most records have a length of 0.

Parameters

segment

The segment the record is part of

Reimplemented in Apple::OMFFormat::Segment::DataRecord, Apple::OMFFormat::Segment::ValueRecord, and Apple::OMFFormat::Segment::ExpressionRecord.

ReadData()

void OMFFormat::Segment::Record::ReadData ( size_t bytes, offset_t offset, void * buffer ) const

virtual

Attempts to read data from the in-memory image, if possible, it can be assumed that offset + bytes <= GetMemoryLength()

Reimplemented in Apple::OMFFormat::Segment::DataRecord, Apple::OMFFormat::Segment::ValueRecord, and Apple::OMFFormat::Segment::ExpressionRecord.
