ExposedPorts (ICECompoundNode)

Description

Returns an Array of 2 ICENodePortCollection objects. The first collection contains the exposed ports and the second one the associated compound node ports also known as proxy ports. The collections work as a pair, the exposed port at position 0 in the first collection matches the node port at position 0 in the second collection, etc.

The exposed ports are the contained nodes ports of a compound node and act as connection points to outer nodes. These ports can be either ICENodeInputPort or ICENodeOutputPort objects. The This property and the AddExposedParamToICECompoundNode command are typically used for exposing the contained node ports to other graph nodes.

C# Syntax

// get accessor
Object rtn = ICECompoundNode.ExposedPorts;
