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 java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

getOperands

public java.util.Collection<Node> getOperands()

Specified by:

getOperands in class Node

Returns:

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