Detailed Description

A node in the rendering graph described by a Compositor.

Constructor & Destructor Documentation

CompositorNode() [1/2]

nkGraphics::CompositorNode::CompositorNode

(

)

Constructor. In theory, should never be called by external code, see Compositor::addNode().

CompositorNode() [2/2]

nkGraphics::CompositorNode::CompositorNode ( const CompositorNode &  )

delete

Copy constructor.

~CompositorNode()

virtual nkGraphics::CompositorNode::~CompositorNode ( )

virtual

Destructor.

Member Function Documentation

addOperations()

virtual TargetOperations* nkGraphics::CompositorNode::addOperations ( )

pure virtual

Adds an operation within the node.

Returns

The newly created operation. The node owns the memory allocated, external code should never delete it. See deleteOperations().

getOperations()

TargetOperations* nkGraphics::CompositorNode::getOperations

(

unsigned int

index

)

const

Returns an existing operation.

Parameters

index

The index if the operation to retrieve.

getOperationsCount()

unsigned int nkGraphics::CompositorNode::getOperationsCount

(

)

const

Returns

The number of operations active in the node.

deleteOperations()

virtual void nkGraphics::CompositorNode::deleteOperations ( unsigned int  index )

virtual

Erases and frees the memory of an operation.

Parameters

index

The index of the operation to free.

changeOperationsOrder()

virtual void nkGraphics::CompositorNode::changeOperationsOrder ( unsigned int  fromIndex, unsigned int  toIndex  )

virtual

Changes the order of operations within the node. This changes the rendering, as currently the operations are executed sequentially.

Parameters

fromIndex	The index of the target to move.
toIndex	The index to which the operation should be moved.

getName()

nkMemory::StringView nkGraphics::CompositorNode::getName

(

)

const

Returns

The name attached to the node.

getActive()

bool nkGraphics::CompositorNode::getActive

(

)

const

Returns

Whether the node is active (true) or not (false).

setName()

void nkGraphics::CompositorNode::setName

(

const nkMemory::StringView &

name

)

Sets the name used by the node.

Parameters

name	The name to use.

setActive()

virtual void nkGraphics::CompositorNode::setActive ( bool  value )

virtual

Activates or not the node for rendering. A deactivated node won't participate in the rendering pipeline.

Parameters

value

If the node is active (true) or not (false).

renderOperations()

virtual void nkGraphics::CompositorNode::renderOperations ( )

virtual

Triggers a rendering. In theory, should never be called by external code. Prefer to use Compositor::renderChain.

exportClassToTree()

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

overridevirtual

Basic exporting capabilities.

Parameters

rootNode

The tree to export to.

Implements nkExport::Exportable.

importClassFromTree()

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

overridevirtual

Basic importing capabilities.

Parameters

rootNode

The tree to import from.

Implements nkExport::Exportable.

operator=()

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

delete

Copy operator.
