public abstract class OSnLNode
extends java.lang.Object

The OSnLNode class represents a node in an expression tree for a nonlinear function (linear ones being special cases) and provide convenience methods to process the node. It is an abstract (or generic) node from which we derive concrete operator nodes.

Constructor Detail

OSnLNode

public OSnLNode()

Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

Returns:

the string representation of the OSnLNode object.

reLabelVariableIndices

public boolean reLabelVariableIndices(int[] newVariableIndices)

relabel variable indices, e.g. X0 -> X2; X1 -> X0; X2 -> X1.

Parameters:

newVariableIndices - holds the new varialbe indices. For the example above it would be [2, 0, 1].

Returns:

whether the relabeling is successful or not.
