All Implemented Interfaces:

CollectionConstraint

Enclosing interface:

CollectionConstraint

public static class CollectionConstraint.AllValuesIn
extends Object
implements CollectionConstraint

CollectionConstraint which validates all members of a Collection. All members must be vaild according to the supplied PropertyConstraint, and the total number of members must be acceptable by the given cardinality constraint.

Constructor Detail

AllValuesIn

public AllValuesIn(PropertyConstraint pc,
                   Location card)

Create an AllValuesIn based upon a PropertyConstraint and a cardinality.

Parameters:

pc - the PropertyConstraint to apply to each property value

card - the cardinality constraint restricting the number of values

Method Detail

getPropertyConstraint

public PropertyConstraint getPropertyConstraint()

Get the PropertyConstraint used to validate each property value.

Returns:

the PropertyConstraint used

getCardinalityConstraint

public Location getCardinalityConstraint()

Get the cardinality constraint used to validate the number of property values.

Returns:

the cardinality constraint as a Location

accept

public boolean accept(Object o)

Description copied from interface: CollectionConstraint

accept returns true if the value fulfills the constraint.

Specified by:

accept in interface CollectionConstraint

Parameters:

o - a Collection to check.

Returns:

true if the values are acceptable powerUser Manually compare items with the CollectionConstraint. Node: this will ususaly be done for you in an AnnotationType instance

validateAddValue

public boolean validateAddValue(Collection oldcol,
                                Object newValue)

Description copied from interface: CollectionConstraint

Return true iff the Collection formed by adding newValue to current would be accepted by this constraint. Implementations may not assume that current is valid.

Specified by:

validateAddValue in interface CollectionConstraint

Parameters:

oldcol - a Collection containing the current values

newValue - the new value to add

Returns:

true if adding the new value will result in an acceptable property

validateRemoveValue

public boolean validateRemoveValue(Collection oldcol,
                                   Object victim)

Description copied from interface: CollectionConstraint

Return true iff the Collection formed by removing newValue from current would be accepted by this constraint. Implementations may not assume that current is valid. However, current will already have been checked to ensure that it contains victim.

Specified by:

validateRemoveValue in interface CollectionConstraint

Parameters:

oldcol - a Collection containing the current values

victim - the value to remove

Returns:

true if removing the victim will result in an acceptable property value set

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

subConstraintOf

public boolean subConstraintOf(CollectionConstraint cc)

Description copied from interface: CollectionConstraint

subConstraintOf returns true if the constraint is a sub-constraint.

A pair of constraints super and sub are in a superConstraint/subConstraint relationship if every object accepted by sub is also accepted by super. To put it another way, if instanceOf was used as a set-membership indicator function over some set of objects, then the set produced by super would be a superset of that produced by sub.

It is not expected that constraints will neccesarily maintain references to super/sub types. It will be more usual to infer this relationship by introspecting the constraints themselves. For example, CollectionConstraint.ByClass will infer subConstraintOf by looking at the possible class of all items matching subConstraint.

Specified by:

subConstraintOf in interface CollectionConstraint

Parameters:

cc - a CollectionConstraint to check.

Returns:

a boolean. Usefull when attempting to compare two constraints to see if it is necisary to retain both. You may want to check the more general or the more specific constraint only.

toString

public String toString()

Overrides:

toString in class Object
