ICENodeContainer Class Reference

## Detailed Description

The ICENodeContainer object represents the base class for containers in a node graph.

Node graph containers include ICETree and ICECompoundNode objects. The API of the ICENodeContainer allows for visiting all the nodes contained by a graph or sub-graph recursively.

## Constructor & Destructor Documentation

ICENodeContainer | ( |  | ) |

Default constructor.

~ICENodeContainer | ( |  | ) |

Default destructor.

ICENodeContainer | ( | const CRef & | in_ref | ) |

Constructor.

Parameters:

  in_ref | constant reference object.

ICENodeContainer | ( | const ICENodeContainer & | in_obj | ) |

Copy constructor.

Parameters:

  in_obj | constant class object.

## Member Function Documentation

bool IsA | ( | siClassID | in_ClassID | ) | const`[virtual]`

Returns true if a given class type is compatible with this API class.

Parameters:

  in_ClassID | class type.

Returns:
  true if the class is compatible, false otherwise.

Reimplemented from ICENode.

Reimplemented in ICECompoundNode, and ICETree.

siClassID GetClassID | ( |  | ) | const`[virtual]`

Returns the type of the API class.

Returns:
  The class type.

Reimplemented from ICENode.

Reimplemented in ICECompoundNode, and ICETree.

ICENodeContainer& operator= | ( | const ICENodeContainer & | in_obj | ) |

Creates an object from another object. The newly created object is set to empty if the input object is not compatible.

Parameters:

  in_obj | constant class object.

Returns:
  The new ICENodeContainer object.

ICENodeContainer& operator= | ( | const CRef & | in_ref | ) |

Creates an object from a reference object. The newly created object is set to empty if the input reference object is not compatible.

Parameters:

  in_ref | constant class object.

Returns:
  The new ICENodeContainer object.

Reimplemented from ICENode.

Reimplemented in ICECompoundNode, and ICETree.

CRefArray GetNodes | ( |  | ) | const

Returns each ICENode in the graph. This function is typically used for iterating over an entire node graph. The returned array can contain basic ICENode and ICECompoundNode objects but not the inner nodes of ICECompoundNode objects. To access these inner-nodes you need to call ICENodeContainer::GetNodes on their respective ICECompoundNode parent.

Returns:
  Array of references to ICENode objects.

Example:
  This example demonstrates how to traverse a node graph with ICENodeContainer

              void CreateNodeGraph( );
              void TraverseNodeGraph( const ICENode& in_node );

              // Create the node graph first

              Application xsi;
              Selection sel = xsi.GetSelection();
              X3DObject cube = sel[0];

              ICETree cubeICETree = cube.GetActivePrimitive().GetICETrees()[0];

              TraverseNodeGraph( cubeICETree );

              void TraverseNodeGraph( const ICENode& in_node )
              {
                  Application xsi;

                  // Log the visited node name
                  xsi.LogMessage( in_node.GetName() );

                  CRefArray nodes;
                  if ( in_node.IsA( siICENodeContainerID ) )
                  {
                      //The input node might be a ICETree or ICECompoundNode, let's get their ICENodes
                      ICENodeContainer container( in_node.GetRef() );
                      nodes = container.GetNodes();
                  }

CRefArray GetDataModifierNodes | ( |  | ) | const

Returns each ICEDataModifierNode object in a graph. As for ICENodeContainer::GetNodes, the returned array doesn't contain the inner ICEDataModifierNode objects of a ICECompoundNode object.

Example:
  See the ICEDataModifierNode class reference page for a code example.

Returns:
  Array of references to ICEDataModifierNode objects.

CRefArray GetDataProviderNodes | ( |  | ) | const

Returns all the ICEDataProviderNode objects of a graph. As for ICENodeContainer::GetNodes, the returned array doesn't contain the inner ICEDataProviderNode objects of a ICECompoundNode object. To access the inner ICEDataProviderNode objects, call ICENodeContainer::GetDataProviderNodes on their ICECompoundNode parent.

Example:
  See the ICEDataProviderNode class reference page for a code example.

Returns:
  Array of references to ICEDataProviderNode objects.

CRefArray GetCompoundNodes | ( |  | ) | const

Returns each ICECompoundNode object in a graph. As for ICENodeContainer::GetNodes, the returned array doesn't contain the inner ICECompoundNode objects of a ICECompoundNode object. To access the inner ICECompoundNode objects, call ICENodeContainer::GetCompoundNodes on their ICECompoundNode parent.
