All Implemented Interfaces:

Belonging, BusinessSmartComponent, java.lang.Cloneable, java.lang.Comparable, Criteria, Expression, java.io.Serializable

public class CriteriaImpl

extends ExpressionImpl

implements Criteria, java.lang.Cloneable

The default Criteria implementation.

Unlinke most Belonging implementations, this does not attempt to clone everything.

All values are initialized to null.

Method Detail

getCriteria

public java.lang.Object getCriteria()

Get the value of criteria

Specified by:

getCriteria in interface Criteria

setCriteria

public void setCriteria(java.lang.Object criteria)

Set the value of criteria

Specified by:

setCriteria in interface Criteria

Parameters:

criteria - criteria to be added

getProperty

public java.lang.String getProperty()

Get the value of property

Specified by:

getProperty in interface Criteria

setProperty

public void setProperty(java.lang.String property)

Set the value of property

Specified by:

setProperty in interface Criteria

getScope

public java.lang.String getScope()

Get the value of scope

Specified by:

getScope in interface Criteria

setScope

public void setScope(java.lang.String scope)

Set the value of scope

Specified by:

setScope in interface Criteria

getComparator

public java.lang.String getComparator()

Get the value of comparator

Specified by:

getComparator in interface Criteria

setComparator

public void setComparator(java.lang.String comparator)

Set the value of comparator

Specified by:

setComparator in interface Criteria

value

public Belonging value()

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

Specified by:

value in interface Belonging

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.

Specified by:

interfaceName in interface Belonging

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.

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

Set this Criteria's attributes from the specified query sting, which must be of the form "property comparator criteria" (e.g. "identifier == '1234').

Specified by:

valueOf in interface Expression

Overrides:

valueOf in class ExpressionImpl

Throws:

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