Public Types
enum	opcode_type {   Zero = 0 , BlockCopy = 1 , RepeatedBlock = 2 , InterleaveRepeatBlockWithBlockCopy = 3 ,   InterleaveRepeatBlockWithZero = 4 }

Public Member Functions
void	ReadFile (Linker::Reader &rd)
	Reads an initialization pattern and initializes this structure.
void	WriteFile (Linker::Writer &wr) const
	Writes the initialization pattern to a stream.
offset_t	CodeSize () const
	Size of the packed data, as stored in the file.
offset_t	DataSize () const
	Size of the unpacked data, as loaded into memory.
void	ExpandData (Linker::Buffer &buffer) const
	Expand the pattern into unpacked data and append it to the buffer.

Static Public Member Functions
static uint32_t	ReadValue (Linker::Reader &rd)
	Reads a variable length value as used by some patterns.
static size_t	GetValueSize (uint32_t value, size_t size_hint=0)
	Determines the required number of bytes to store this value, with an optional minimum size.
static void	WriteValue (Linker::Writer &wr, uint32_t value, size_t size_hint=0)
	Writes a variable length value, with an optional minimum size.

Public Attributes
offset_t	file_offset
	Offset at which this pattern is stored in the file (only relevant for dumping)
opcode_type	opcode
	The pattern type.
uint32_t	count
	Generic count parameter, used for repeating or zero filling data.
std::vector< uint8_t >	common_data
	Sequence of data to be used, possibly repeatedly.
std::vector< std::vector< uint8_t > >	custom_data
	Equal sized sequences of data to be inserted between repeated common data.

Detailed Description

Pattern initialization data.

For pattern initialized data sections (data sections that are not unpacked), they are stored in the file as a sequence of pattern initialization data. This class represents a single pattern in a stream of patterns.
