Description copied from class: Node

Accept method of the visitor pattern

Specified by:

accept in class Node

Type Parameters:

R - Result type of the operation.

P - Parameter type.

Parameters:

visitor - The visitor to be applied to this node.

p - The parameter for this operation.

toString

Overrides:

toString in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

getOperands

public Collection<Node> getOperands()

Specified by:

getOperands in class Node

Returns:

A collection containing all of the operand Nodes of this Node.
