Class Description

The ICECompoundNode object represents a node sub-graph.

ICECompoundNodes may enclose other regular ICENode objects or specialized ones such as ICECompoundNode and ICEDataProviderNode. An ICECompoundNode is like a basic ICENode with input and output ports. ICETree objects cannot be part of a ICECompoundNode sub-graph.

Constructor.

Parameters:

in_ref constant reference object.

ICECompoundNode ( const ICECompoundNode & in_obj )

Copy constructor.

Parameters:

in_obj constant class object.

Member Function Documentation

bool IsA ( siClassID in_ClassID ) const [virtual]

Search for all occurrences

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 ICENodeContainer.

siClassID GetClassID ( ) const [virtual]

Search for all occurrences

Returns the type of the API class.

Returns:: The class type.

Reimplemented from ICENodeContainer.

ICECompoundNode& operator= ( const ICECompoundNode & 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 ICECompoundNode object.

ICECompoundNode& 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 ICECompoundNode object.

Reimplemented from ICENodeContainer.

CStatus GetExposedPorts	(	CRefArray &	out_exposedPorts,
		CRefArray &	out_nodePorts
	)		const

Search for all occurrences

Returns 2 arrays of ICENodePort objects. The first array contains the ports exposed by the ICECompoundNode and the second one contains the associated ICECompoundNode ports also known as proxy ports. The arrays works as a pair: the exposed ICENodePort at position 0 in the first array matches the ICENodePort at position 0 in the second array, etc.

The exposed ICENodePorts are basically the contained nodes ports of a ICECompoundNode and act as connection points to outer nodes. These ports can be either ICENodeInputPort or ICENodeOutputPort objects. The ICECompoundNode::GetExposedPorts method and the AddExposedParamToICECompoundNode command are typically used for exposing the contained ICENodePorts to other graph nodes.

Parameters:

out_exposedPorts	Array of ports exposed by the ICECompoundNode object.
out_nodePorts	Array of this ICECompoundNode object's ports.

Returns:: CStatus::OK Success.; CStatus::Fail Operation failed.

Example:

This example demonstrates how to log the ICECompoundNode exposed ports.
