See also xnCreateMockNode(). For full details and usage, see xnCreateMockNodeBasedOn
Creates a production node. If the tree specifies additional needed nodes, and those nodes do not exist, they will be created too, and passed to this node as input. For full details and usage, see xnCreateProductionTree

Enumerates all available production trees for a specific node type. The trees populated in the list should be freed by calling xnNodeInfoListFree() once not needed. For full details and usage, see xnEnumerateProductionTrees
XnStatus xn::Context::FindExistingNode | ( | XnProductionNodeType | type, | |
ProductionNode & | node | |||

XnStatus xn::Context::GetGlobalErrorState | ( | ) | [inline] |
Gets the global error state of the context. If one of the nodes in the context is in error state, that state will be returned. If more than one node is in error state, XN_STATUS_MULTIPLE_NODES_ERROR is returned. An application can query each node error state by calling xnGetNodeErrorState(). For full details and usage, see xnGetGlobalErrorState
XnBool xn::Context::GetGlobalMirror | ( | ) | [inline] |
Gets the global mirror flag. For full details and usage, see xnGetGlobalMirror
XnStatus xn::Context::GetProductionNodeByName | ( | const XnChar * | strInstanceName, | |
