allocate()

template<typename AllocatorT >

MemChunk castor3d::GpuBaseBufferT< AllocatorT >::allocate ( VkDeviceSize size )

noexcept

Allocates a memory chunk for a CPU buffer.

Parameters

[in]

size

The requested memory size.

Returns

The memory chunk offset.

deallocate()

template<typename AllocatorT >

void castor3d::GpuBaseBufferT< AllocatorT >::deallocate ( MemChunk const & mem )

noexcept

Deallocates memory.

Parameters

[in]

mem

The memory chunk.

getBuffer() [1/2]

template<typename AllocatorT >

ashes::BufferBase const & castor3d::GpuBaseBufferT< AllocatorT >::getBuffer ( ) const

inlinenoexcept

Returns

The internal buffer.

noexcept

Parameters

[in]

size

The requested memory size.

Returns

true if there is enough remaining memory for given size.
