Detailed Description

NodeList is a container that works as input and output node listing for filtering and rendering.

Main usage points are:

Viewport2D contains a root NodeListRenderPass used as input for other node list or draw objects render passes. It is used if no specific input NodeListRenderPass is defined.

Since
Kanzi 3.9.0

Member Typedef Documentation

Container type for added or removed nodes.

Member Function Documentation

static NodeListSharedPtr kanzi::NodeList::create ( )
static

Create a node list.

void kanzi::NodeList::clear ( )

Clear the node list.

iterator kanzi::NodeList::filterPassBegin ( )

Begins the extract or filtering pass.

During the pass, the node list is assumed to be in the same state as on the last pass. Inconsistencies during insertion alter the internal state for removed nodes and mark the list dirty. The user must call insert() to insert a node into the node list into the current iterator location. The cycle must be manually ended when the iteration stops.

void kanzi::NodeList::filterPassEnd ( iterator  lastLocation)

Ends the extract or filtering pass.

Parameters
lastLocationLast location returned from insert().
iterator kanzi::NodeList::insert ( iterator  insertLocation,
NodeSharedPtr  node 
)

Insert new node into the end of the list.

Parameters
insertLocationLocation to insert to, must come from an earlier call to insert() or filterPassBegin().
nodeNode to insert.
Returns
Next insert location.
void kanzi::NodeList::copyListData ( const NodeList other)

Assign contents from another node list.

Dirty flag is set.

Parameters
otherSource node list.
DiffNodeContainer::const_iterator kanzi::NodeList::beginAddedNodes ( ) const
inline

Returns an iterator to the beginning of the added nodes list.

Returns
Iterator to the beginning of added nodes.
DiffNodeContainer::const_iterator kanzi::NodeList::endAddedNodes ( ) const
inline

Returns an iterator to the beginning of the added nodes list.

Returns
Iterator to the beginning of added nodes.
DiffNodeContainer::const_iterator kanzi::NodeList::beginRemovedNodes ( ) const
inline

Returns an iterator to the beginning of the removed nodes list.

Returns
Iterator to the beginning of removed nodes.
DiffNodeContainer::const_iterator kanzi::NodeList::endRemovedNodes ( ) const
inline

Returns an iterator to the beginning of the removed nodes list.

Returns
Iterator to the beginning of removed nodes.
bool kanzi::NodeList::isDirty ( ) const
inline

Indicates whether the node list is dirty, i.e.

has changed in any way.

Returns
True if the list is in dirty state, false otherwise.
void kanzi::NodeList::setDirty ( bool  flag)
inline

Sets the dirty flag in the node list.

Parameters
flagNew dirty flag state.
