Method Detail

isInvertible

protected java.lang.Boolean isInvertible()

Overrides:

isInvertible in class AbstractSpecification<T>

invert

protected Specification<T> invert()

Overrides:

invert in class AbstractValueBoundSpecification<T>

getBinaryRelation

protected RelationalOperator getBinaryRelation(java.lang.Boolean negated)

Specified by:

getBinaryRelation in class AbstractValueBoundSpecification<T>

Parameters:

negated - when true the returned binary relation will be inverted

Returns:

the mathematical binary relation bound to this value bound specification

getDisjointDecision

protected java.lang.Boolean getDisjointDecision(RelationalOperator candidateRelationalOperator,
                                                java.lang.Object candidateOperandValue)

Specified by:

getDisjointDecision in class AbstractValueBoundSpecification<T>

Returns:

true if the given candidate relation/operand pair leads to a disjoint relationship with this value bound specification

isDisjointWith

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

Specified by:

isDisjointWith in interface Specification<T>

Overrides:

isDisjointWith in class AbstractValueBoundSpecification<T>

isSatisfiedBy

public java.lang.Boolean isSatisfiedBy(T candidate)
