Member Function Documentation

ref()

void SkRefCntBase::ref ( ) const

inlineinherited

Increment the reference count.

Must be balanced by a call to unref().

size()

virtual size_t SkMesh::IndexBuffer::size ( ) const

pure virtual

unique()

bool SkRefCntBase::unique ( ) const

inlineinherited

May return true if the caller is the only owner.

Ensures that all previous owner's actions are complete.

unref()

void SkRefCntBase::unref ( ) const

inlineinherited

Decrement the reference count.

If the reference count is 1 before the decrement, then delete the object. Note that if this is the case, then the object needs to have been allocated via new, and not on the stack.

update()

bool SkMesh::IndexBuffer::update	(	GrDirectContext *	,
		const void *	data,
		size_t	offset,
		size_t	size
	)

Modifies the data in the IndexBuffer by copying size bytes from data into the buffer at offset.

Fails if offset + size > this->size() or if either offset or size is not aligned to 4 bytes. The GrDirectContext* must match that used to create the buffer. We take it as a parameter to emphasize that the context must be used to update the data and thus the context must be valid for the current thread.
