Class OperationProxy

java.lang.Object
hussam.math.operations.OperationProxy

All Implemented Interfaces:

Operation, java.io.Serializable, java.lang.Cloneable

public class OperationProxy
extends java.lang.Object
implements Operation

This is a proxy to hide an Operation. The proxy operation takes an operation as argument. You can hide any operation inside this proxy. The implementation is only redirting to the hidden operation.

result

public double result()
              throws MathException

Specified by:

result in interface Operation

The result value.

MathException - if there is a Math Exception!!

toString

public java.lang.String toString()

Returns the hidden operation.toString()

Overrides:

toString in class java.lang.Object

Returns:

the hidden operation.toString();

getOperation

public Operation getOperation()

Returns the hidden operation.

The operation hidden.

clone

public OperationProxy clone(OperatorSourceImpl s)
                     throws java.lang.CloneNotSupportedException

Description copied from interface: Operation

This method clones the operation. Cloning can be achieved by useing the default clone method since Operations are Clonable since Version 3! However, cloning sometimes needs more than what the clone method offers! Notice that this clone method takes an OperatorSource as a parameter, this method should update this source with any arguments needed such as Variables! It can be seen as an implemetation of the Visitor approach. It is also worth to note that this method's implemetation is optional. You can egnore the implemetation of this method and just return

this

.

Specified by:

clone in interface Operation

Parameters:

s - The OperatorSourceImpl.

Returns:

Returns the cloned operation.

Throws:

java.lang.CloneNotSupportedException - If the operation is not clonable.

optimize

public Operation optimize()

Redircts the optimization to the hidden optimization. It may return a new ConstantNumber if the hidden operation is a constantnumber.

Specified by:

optimize in interface Operation

Returns:

an optimized Operation of this operation.
