Detailed Description

template<class BaseInterface, class BufferViewImplType, class TBuffViewObjAllocator>
class Diligent::BufferBase< BaseInterface, BufferViewImplType, TBuffViewObjAllocator >

Template class implementing base functionality for a buffer object.

Template Parameters

BaseInterface	- base interface that this class will inheret (Diligent::IBufferD3D11, Diligent::IBufferD3D12 or Diligent::IBufferGL).
BufferViewImplType	- type of the buffer view implementation (Diligent::BufferViewD3D11Impl, Diligent::BufferViewD3D12Impl or Diligent::BufferViewGLImpl)
TBuffViewObjAllocator	- type of the allocator that is used to allocate memory for the buffer view object instances

Constructor & Destructor Documentation

◆ BufferBase()

template<class BaseInterface, class BufferViewImplType, class TBuffViewObjAllocator>

Diligent::BufferBase< BaseInterface, BufferViewImplType, TBuffViewObjAllocator >::BufferBase	(	IReferenceCounters *	pRefCounters,
		TBuffViewObjAllocator &	BuffViewObjAllocator,
		IRenderDevice *	pDevice,
		const BufferDesc &	BuffDesc,
		bool	bIsDeviceInternal
	)

inline

Parameters

pRefCounters	- reference counters object that controls the lifetime of this buffer.
BuffViewObjAllocator	- allocator that is used to allocate memory for the buffer view instances. This parameter is only used for debug purposes.
pDevice	- pointer to the device.
BuffDesc	- buffer description.
bIsDeviceInternal	- flag indicating if the buffer is an internal device object and must not keep a strong reference to the device.

Member Function Documentation

◆ CreateDefaultViews()

template<class BaseInterface , class BufferViewImplType , class TBuffViewObjAllocator >

void Diligent::BufferBase< BaseInterface, BufferViewImplType, TBuffViewObjAllocator >::CreateDefaultViews ( )

Creates default buffer views.

Creates default shader resource view addressing the entire buffer if Diligent::BIND_SHADER_RESOURCE flag is set
Creates default unordered access view addressing the entire buffer if Diligent::BIND_UNORDERED_ACCESS flag is set

The function calls CreateViewInternal().
