Class ConjunctionCriterion

java.lang.Object
oracle.adf.view.rich.model.Criterion
oracle.adf.view.rich.model.ConjunctionCriterion

public abstract class ConjunctionCriterion

extends Criterion

Represents a group of criterion objects that use one conjuction operator between them. Since this class contains a list of Criterion objects it is possible to build complex hierarchies of Criterion objects as follows.

conjCriterion A
|__attrCriterion A1 (and)
|__conjCriterion A2
|__attrCriterion A21 (or)
|__attrCriterion A22 (or)
|__attrCriterion A22

The hierarchical representation of Criterion objects is especially useful when SQL style inner queries are desired.

Method Summary

abstract ConjunctionCriterion.Conjunction	getConjunction() Returns a conjunction to be used with this ConjunctionCriterion object.
abstract Criterion	getCriterion(java.lang.Object key) Gets the Criterion object located at key within the list.
abstract java.util.List<Criterion>	getCriterionList() Returns the List of Criterion objects that are children on the ConjunctionCriterion.
abstract java.lang.Object	getKey(Criterion criterion) Gets a unique key of the Criterion object within its list, for the current ConjunctionCriterion.
abstract void	setConjunction(ConjunctionCriterion.Conjunction conjunction) Sets the conjunction to use with this ConjunctionCriterion object.

Method Detail

getConjunction

public abstract ConjunctionCriterion.Conjunction getConjunction()

Returns a conjunction to be used with this ConjunctionCriterion object.

Returns:

a ConjunctionType

getCriterionList

public abstract java.util.List<Criterion> getCriterionList()

Returns the List of Criterion objects that are children on the ConjunctionCriterion.

Returns:

a List<Criterion>

getKey

public abstract java.lang.Object getKey(Criterion criterion)

Gets a unique key of the Criterion object within its list, for the current ConjunctionCriterion. If there are nested ConjunctionCriterion objects below the current level then calling this method should return the key of the Criterion object if it is found or null. All Criterion objects can be retrived from the root ConjunctionCriterion.

Parameters:

criterion -

Returns:

a unique key identifying the Criterion object. It's important that the key be unique across all Criterion objects belonging to the root ConjunctionCriterion.

getCriterion

public abstract Criterion getCriterion(java.lang.Object key)

Gets the Criterion object located at key within the list. Calling this method from the root ConjunctionCriterion object will yield the Criterion object (nested at any level in the hierarchy) or null if not found. Calling this from a nested ConjunctionCriterion will delegate the call to the root ConjunctionCriterion

Parameters:

key - the unique key

Returns:

a Criterion object identified by the key

setConjunction

public abstract void setConjunction(ConjunctionCriterion.Conjunction conjunction)

Sets the conjunction to use with this ConjunctionCriterion object.

Parameters:

conjunction - a ConjunctionType instance
