Member Function Documentation

void SkDynamicMemoryWStream::copyTo ( void *  dst) const

More efficient version of read(dst, 0, bytesWritten()).

void SkDynamicMemoryWStream::copyToAndReset ( void *  dst)

Equivalent to copyTo() followed by reset(), but may save memory use.

sk_sp<SkData> SkDynamicMemoryWStream::detachAsData ( )

Return the contents as SkData, and then reset the stream.

std::unique_ptr<SkStreamAsset> SkDynamicMemoryWStream::detachAsStream ( )

Reset, returning a reader stream with the current content.

void SkDynamicMemoryWStream::reset ( )

Reset the stream to its original, empty, state.

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

Called to write bytes to a SkWStream.

Returns true on success

Parameters
bufferthe address of at least size bytes to be written to the stream
sizeThe number of bytes in buffer to write to the stream
Returns
true on success

Implements SkWStream.

bool SkDynamicMemoryWStream::writeToAndReset ( SkWStream dst)

Equivalent to writeToStream() followed by reset(), but may save memory use.
