		size_t	size
	)

reset()

void SkDynamicMemoryWStream::reset

(

)

Reset the stream to its original, empty, state.

SizeOfPackedUInt()

static int SkWStream::SizeOfPackedUInt ( size_t  value )

staticinherited

This returns the number of bytes in the stream required to store 'value'.

write()

bool SkDynamicMemoryWStream::write ( const void *  buffer, size_t  size  )

overridevirtual

Called to write bytes to a SkWStream.

Returns true on success

Parameters

buffer	the address of at least size bytes to be written to the stream
size	The number of bytes in buffer to write to the stream

Returns

true on success

Implements SkWStream.

write16()

bool SkWStream::write16 ( U16CPU  value )

inlineinherited

write32()

bool SkWStream::write32 ( uint32_t  v )
