Nodes (ICENodeContainer)

Description

Returns an ICENodeCollection containing all nodes in this container, including both ICENode and the immediate ICECompoundNode objects. To access the inner nodes of ICECompoundNode objects you need to call this property on their respective ICECompoundNode parents (via ICENodeContainer.CompoundNodes).

This property is typically used for iterating over an entire node graph. For example, start by calling this property on the ICETree. While iterating over the returned collection, when you find a compound node, call ICENodeContainer.CompoundNodes on it to get any inner compound nodes and so on recursively down through the graph.

C# Syntax

    // get accessor
    ICENodeCollection rtn = ICENodeContainer.Nodes;
