Specified by:
addChildren in interface Logical

addAllChildren

public boolean addAllChildren(java.util.Collection collection)
Adds all of the expressions in the specified collection to our list of children expressions.
Specified by:
addAllChildren in interface Logical

clearChildren

public void clearChildren()
Removes all children expressions.
Specified by:
clearChildren in interface Logical

containsChildren

public boolean containsChildren(Expression element)
Returns true if the specified expression is one of our children.
Specified by:
containsChildren in interface Logical

Specified by:
isEmptyChildren in interface Logical

iteratorChildren

public java.util.Iterator iteratorChildren()
Returns an iterator over the list of children expressions.
Specified by:
iteratorChildren in interface Logical

removeChildren

public boolean removeChildren(Expression element)
Removes a single child expression from us.
Specified by:
removeChildren in interface Logical

removeAllChildren

public boolean removeAllChildren(java.util.Collection collection)
Removes, from our children, all of the expressions specified.
Specified by:
removeAllChildren in interface Logical

retainAllChildren

public boolean retainAllChildren(java.util.Collection collection)

value

public Belonging value()
value() is a more typesafe implementation of clone()
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.
Overrides:
interfaceName in class ExpressionImpl
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.

Overrides:
setByValue in class ExpressionImpl
Tags copied from interface: Belonging
Parameters:
belonging - The Belonging to use for initialization.

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.
Overrides:
valueOf in class ExpressionImpl
Throws:
java.lang.IllegalArgumentException - thrown on an invalid expression string.
