Constructor Summary

SimpleReferenceConstraint(SimpleParameter constraintParameter, int comparisonOperator)
Creates a new SimpleReferenceConstraint from a reference SimpleParameter and a comparison operator, which is one of the values defined in the Constraint interface.

SimpleReferenceConstraint(StringBuffer representation)
The standard constructor for the interface Storable.

Method Summary

boolean	check(Object value) Checks value for the constraint defined in the Constraint.
SimpleReferenceConstraint	clone() This method returns a deep copy of the current instance.
void	fromXML(StringBuffer representation) Parses a ReferenceConstraint from the XML representation as returned by ReferenceConstraint.toXML().
StringBuffer	toXML() This method returns an XML representation as StringBuffer of an instance of the implementing class.

Constructor Detail

SimpleReferenceConstraint

public SimpleReferenceConstraint(SimpleParameter constraintParameter,
                                 int comparisonOperator)

Creates a new SimpleReferenceConstraint from a reference SimpleParameter and a comparison operator, which is one of the values defined in the Constraint interface.

Parameters:

constraintParameter - the reference SimpleParameter

comparisonOperator - the comparison operator

SimpleReferenceConstraint

public SimpleReferenceConstraint(StringBuffer representation)
                          throws NonParsableException

The standard constructor for the interface Storable. Creates a new SimpleReferenceConstraint from its XML representation.

Parameters:

representation - the XML representation as StringBuffer

Throws:

NonParsableException - if representation could not be parsed

Method Detail

clone

public SimpleReferenceConstraint clone()
                                throws CloneNotSupportedException

Description copied from interface: Constraint

This method returns a deep copy of the current instance.

Specified by:

clone in interface Constraint

Specified by:

clone in class ReferenceConstraint

Returns:

a deep copy of the current instance

Throws:

CloneNotSupportedException - if the Constraint could not be cloned

Cloneable

check

public boolean check(Object value)

Description copied from interface: Constraint

Checks value for the constraint defined in the Constraint. If the constraint is fulfilled, true is returned.

Specified by:

check in interface Constraint

Specified by:

check in class ReferenceConstraint

Parameters:

value - the Object to be checked

Returns:

true if the constraint is fulfilled, false otherwise

toXML

public StringBuffer toXML()

Description copied from interface: Storable

This method returns an XML representation as StringBuffer of an instance of the implementing class.

Specified by:

toXML in interface Storable

Overrides:

toXML in class ReferenceConstraint

Returns:

the XML representation

fromXML

public void fromXML(StringBuffer representation)
             throws NonParsableException

Description copied from class: ReferenceConstraint

Parses a ReferenceConstraint from the XML representation as returned by ReferenceConstraint.toXML().

Overrides:

fromXML in class ReferenceConstraint

Parameters:

representation - the XML representation

Throws:

NonParsableException - if the XML code could not be parsed
