	Record (record_type type)

virtual offset_t	GetMemoryLength (const Segment &segment, offset_t current_address) const
	Returns the amount of memory the record occupies when loaded into memory. Most records have a length of 0.

virtual void	Dump (Dumper::Dumper &dump, const OMFFormat &omf, const Segment &segment, unsigned index, offset_t file_offset, offset_t address) const
	Displays information pertaining to this record.

virtual void	AddSignals (Dumper::Block &block, offset_t current_segment_offset) const
	If this is a relocation record, add the relocation signals to the block.

virtual void	ReadData (size_t bytes, offset_t offset, void *buffer) const
	Attempts to read data from the in-memory image, if possible, it can be assumed that offset + bytes <= GetMemoryLength()
