value

public Belonging value()

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

Specified by:

Overrides:

value in class ExpressionImpl

Returns:

a clone of this instance

interfaceName

public java.lang.String interfaceName()

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

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.

Specified by:

setByValue in interface Belonging

Overrides:

setByValue in class ExpressionImpl

Following copied from interface: com.beasys.commerce.foundation.Belonging

Parameters:

belonging - The Belonging to use for initialization.

compareTo

public int compareTo(java.lang.Object o)

Compare this belonging to another

Specified by:

compareTo in interface java.lang.Comparable

Overrides:

compareTo in class ExpressionImpl

Parameters:

o - target object for comparision

Returns:

0 objects are equal

valueOf

public void valueOf(java.lang.String expression)
             throws java.lang.IllegalArgumentException

Populate this Logical from the given expression string.

Specified by:

valueOf in interface Expression

Overrides:

valueOf in class ExpressionImpl

Throws:

java.lang.IllegalArgumentException - thrown on an invalid expression string.
