Method Detail

getNot

public boolean getNot()

Get the value of not

Specified by:

getNot in interface Expression

setNot

public void setNot(boolean not)

Set the value of not

Specified by:

setNot in interface Expression

value

public Belonging value()

value() is a more typesafe implementation of clone()

Returns:

a clone of this instance

clone

public java.lang.Object clone()

Description copied from interface: Belonging

Returns a shallow copy of the Belonging instance.

Overrides:

clone in class java.lang.Object

Tags copied from interface: Belonging

Returns:

A shallow copy of this Belonging.

interfaceName

public java.lang.String interfaceName()

interfaceName() returns the unqualified name of the interface from the UML model.

Returns:

the unqualified name of the belonging interface

setByValue

public void setByValue(Belonging value)

It is possible to call set-by-value with a superclass.

If that is the case, only the fields in the superclass will be set in this instance. The remaining fields get the default values. It is also possible to call set-by-value with a subclass. In this case, the specialized fields in the subclass will be ignored. The overridden fields in the subclass will be populated.

o - target object for comparision

Returns:

0 objects are equal

o - the Object to be compared.

Returns:

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Throws:

java.lang.ClassCastException - if the specified object is not of the same type as this Belonging.

toString

public java.lang.String toString()

Render the expression as a string.

Specified by:

toString in interface Expression
