          net.sourceforge.domian.specification.DisjunctionSpecification<T>

All Implemented Interfaces:

CompositeSpecification<T>, Specification<T>

final class DisjunctionSpecification<T>
extends AbstractCompositeSpecification<T>

A composite specification where at least one of the wrapped specifications must be satisfied for this overall composite specification to be satisfied.

The boolean logic operator equivalent is OR.

Method Detail

isSatisfiedBy

public java.lang.Boolean isSatisfiedBy(T candidate)

Specified by:

isSatisfiedBy in interface Specification<T>

Overrides:

isSatisfiedBy in class AbstractCompositeSpecification<T>

isDisjointWith

public java.lang.Boolean isDisjointWith(Specification<?> specification)

Specified by:

isDisjointWith in interface Specification<T>

Overrides:

isDisjointWith in class AbstractSpecification<T>

isSpecifyingAllInstancesOfItsType

protected java.lang.Boolean isSpecifyingAllInstancesOfItsType()

Specified by:

isSpecifyingAllInstancesOfItsType in class AbstractCompositeSpecification<T>

Returns:

true if this specification will approve all possible instances of its declared type

purify

protected AbstractSpecification<T> purify(boolean doPurifyInversions)

Description copied from class: AbstractSpecification

Purify this specification.

This may imply both simplification of the specification object graph, as well as applying boolean algebra on the overall logical expression.

Overrides:

purify in class AbstractSpecification<T>

Parameters:

doPurifyInversions - if false leave inversions alone (they must be purified only when spec creation is completed)

Returns:

a purified specification

isInvertible

protected java.lang.Boolean isInvertible()

Overrides:

isInvertible in class AbstractSpecification<T>

invert

protected Specification<T> invert()

Overrides:

invert in class AbstractSpecification<T>

doBooleanAlgebraInversion

private Specification<T> doBooleanAlgebraInversion()
