Method Detail

evaluate

<T> T evaluate(Assignments assignments)

Returns the result of evaluating this Node using the values of the specified Assignments.

Parameters:

assignments - represents the values to assign to any variables used in the evaluation of this Node

Returns:

the result of evaluating this Node using the values of the specified Assignments

getNodeCount

int getNodeCount()

Returns the total number of nodes represented by this Node - including any child-nodes.

getHeight

int getHeight()

Returns the height of this Node.

The height of a node is the number of edges on the longest downward path between that node and a leaf.

getType

Type getType()

Returns the Type of this Node.

This indicates the type of the value returned when #evaluate(Assignments) is called on this Node.

getNodeType

NodeType getNodeType()

Returns the NodeType of this Node.

This can be used to determine if the node is a function, constant or variable node.
