Member Function Documentation

getPassMemorySlot()

ShaderPassMemorySlot* nkGraphics::ConstantBuffer::getPassMemorySlot

(

unsigned int

index

)

Parameters

index

The index of the slot to retrieve.

Returns

The slot requested if available, nullptr else.

getPassMemorySlotReadOnly()

ShaderPassMemorySlot* nkGraphics::ConstantBuffer::getPassMemorySlotReadOnly

(

unsigned int

index

)

const

The read only version of the getter. Use this version when possible, as this avoid a dirtification of the tracking data.

Parameters

index

The index of the slot to retrieve.

Returns

The slot requested if available, nullptr else.

addPassMemorySlot()

ShaderPassMemorySlot* nkGraphics::ConstantBuffer::addPassMemorySlot

(

)

Adds a pass memory slot. Memory slots are fed sequentially, in the order they are declared. Be sure to align all structures within shaders to be coherent with the way the data is fed.

Returns

A freshly allocated memory slot. The buffer is responsible for the memory returned, external code should not delete it. See deletePassMemorySlot().

changePassMemorySlotOrder()

void nkGraphics::ConstantBuffer::changePassMemorySlotOrder	(	unsigned int	fromIndex,
		unsigned int	toIndex
	)

Changes the ordering in the slots, impacting the way they are fed to the buffer.

Parameters

fromIndex	The index of the slot to change.
toIndex	The index to which the slot should be moved.

deletePassMemorySlot()

void nkGraphics::ConstantBuffer::deletePassMemorySlot

(

unsigned int

index

)

Erases and frees a slot.

Parameters

index

The index of the slot to erase.

exportClassToTree()

virtual void nkGraphics::ConstantBuffer::exportClassToTree ( nkExport::Node *  rootNode )

overridevirtual

Basic exporting capabilities.

Parameters

rootNode

The tree to export to.

Implements nkExport::Exportable.

importClassFromTree()

virtual void nkGraphics::ConstantBuffer::importClassFromTree ( nkExport::Node *  rootNode )

overridevirtual

Basic importing capabilities.

Parameters

rootNode

The tree to import from.

Implements nkExport::Exportable.

operator=()

ConstantBuffer& nkGraphics::ConstantBuffer::operator= ( const ConstantBuffer &  )

delete

Copy assignment.
