Detailed Description

Holds a Span of AsyncBufferView (allocated by user) holding available memory for the streams.

Note: User must fill the AsyncBuffersPool::buffers with a Span of AsyncBufferView

Member Function Documentation

◆ createChildView()

Result SC::AsyncBuffersPool::createChildView	(	AsyncBufferView::ID	parentBufferID,
		size_t	offset,
		size_t	length,
		AsyncBufferView::ID &	outChildBufferID )

Creates a child view that references a slice of the parent buffer.

◆ getBuffer()

AsyncBufferView * SC::AsyncBuffersPool::getBuffer ( AsyncBufferView::ID bufferID )

Access the raw AsyncBufferView (if any) at a given bufferID (or nullptr if invalid)

◆ getNumBuffers()

size_t SC::AsyncBuffersPool::getNumBuffers ( ) const

inlinenodiscard

Gets size of buffers held by the pool.

◆ getReadableData()

Result SC::AsyncBuffersPool::getReadableData	(	AsyncBufferView::ID	bufferID,
		Span< const char > &	data )

Access data span owned by the buffer.

◆ getWritableData()

Result SC::AsyncBuffersPool::getWritableData	(	AsyncBufferView::ID	bufferID,
		Span< char > &	data )

Access data span owned by the buffer.

◆ pushBuffer()

Result SC::AsyncBuffersPool::pushBuffer	(	AsyncBufferView &&	buffer,
		AsyncBufferView::ID &	bufferID )

Adds a buffer to the pool in any empty slot (found by scanning from start to end)

◆ refBuffer()

void SC::AsyncBuffersPool::refBuffer ( AsyncBufferView::ID bufferID )

Increments a buffer reference count.

◆ requestNewBuffer()

Result SC::AsyncBuffersPool::requestNewBuffer	(	size_t	minimumSizeInBytes,
		AsyncBufferView::ID &	bufferID,
		Span< char > &	data )

Requests a new available buffer that is at least minimumSizeInBytes, incrementing its refcount.

◆ setBuffers()

void SC::AsyncBuffersPool::setBuffers ( Span< AsyncBufferView > newBuffers )

inline

Sets memory for the new buffers.

◆ setNewBufferSize()

void SC::AsyncBuffersPool::setNewBufferSize	(	AsyncBufferView::ID	bufferID,
		size_t	newSizeInBytes )

Sets the new size in bytes for the buffer.

◆ sliceInEqualParts()

static Result SC::AsyncBuffersPool::sliceInEqualParts	(	Span< AsyncBufferView >	buffers,
		Span< char >	memory,
		size_t	numSlices )

static

Splits a span of memory in equally sized slices, assigning them to buffers and marking them as reusable.

◆ unrefBuffer()

void SC::AsyncBuffersPool::unrefBuffer ( AsyncBufferView::ID bufferID )

Decrements a buffer reference count.

When reference count becomes zero the buffer will be re-used
