CompoundNodes (ICENodeContainer)

Description

Returns an ICECompoundNodeCollection containing all ICECompoundNode objects in this container. This differs from ICENodeContainer.Nodes, which only returns the immediate ICECompoundNode objects but also returns atomic (non-compound) nodes. See ICENodeContainer.Nodes for more information.

C# Syntax

    // get accessor
    ICECompoundNodeCollection rtn = ICENodeContainer.CompoundNodes;

Examples

Python Example

    # Sample code to log all the compound nodes in a graph
