java.lang.Object

org.seedstack.business.specification.ComparableSpecification<T>

Type Parameters:

T - the type of the compared value.

All Implemented Interfaces:

Specification<T>

Direct Known Subclasses:

GreaterThanSpecification, LessThanSpecification

public abstract class ComparableSpecification<T extends Comparable<? super T>>
extends Object
implements Specification<T>

Base class for specifications that compare their expected and candidate value. Those values must implement Comparable.

Constructor Detail

ComparableSpecification

protected ComparableSpecification(T expectedValue)

Creates a comparable specification.

Parameters:

expectedValue - the value used to do the comparison against.

Method Detail

isSatisfiedBy

public boolean isSatisfiedBy(T candidate)

Description copied from interface: Specification

Evaluates if the candidate object passed as argument satisfies the specification.

Specified by:

isSatisfiedBy in interface Specification<T extends Comparable<? super T>>

Parameters:

candidate - the candidate object to check.

Returns:

true if the candidate object satisfies the specification, false otherwise.

getExpectedValue

public T getExpectedValue()

Returns the value serving as reference in the comparison.

Returns:

the value used to do the comparison against.

isExpected

protected abstract boolean isExpected(int compareToResult)

Returns if the comparison result returned by Comparable.compareTo(Object) is the one expected.

Parameters:

compareToResult - the result returned by Comparable.compareTo(Object)

Returns:

true if the result is expected, false otherwise.
