net.sf.staccatocommons.lang.predicate
Class AbstractPredicate<A>

java.lang.Object
  net.sf.staccatocommons.lang.predicate.AbstractPredicate<A>

Type Parameters:

A - the type of argument to evaluate

All Implemented Interfaces:

net.sf.staccatocommons.defs.Applicable<A,Boolean>, net.sf.staccatocommons.defs.Evaluable<A>, net.sf.staccatocommons.defs.predicate.Predicate<A>

Direct Known Subclasses:

AbstractPredicate.Soft, TopLevelPredicate

public abstract class AbstractPredicate<A>
extends Object
implements net.sf.staccatocommons.defs.predicate.Predicate<A>

A AbstractPredicate is an abstract Evaluable.

Predicates in addition understand the basic boolean logic messages not(), and(Evaluable) and or(Evaluable) that perform those operations on evaluation result.

Method Detail

eval

public abstract boolean eval(@NonNull
                             A argument)

Specified by:

eval in interface net.sf.staccatocommons.defs.Evaluable<A>

apply

public Boolean apply(A arg)

Specified by:

apply in interface net.sf.staccatocommons.defs.Applicable<A,Boolean>

not

public net.sf.staccatocommons.defs.predicate.Predicate<A> not()

Specified by:

not in interface net.sf.staccatocommons.defs.predicate.Predicate<A>

Returns:

a AbstractPredicate that negates this AbstractPredicate's result. Non Null.

or

public net.sf.staccatocommons.defs.predicate.Predicate<A> or(@NonNull
                                                             net.sf.staccatocommons.defs.Evaluable<? super A> other)

Returns a predicate that, performs a short-circuit logical-or between this AbstractPredicate's eval(Object) and other

Specified by:

or in interface net.sf.staccatocommons.defs.predicate.Predicate<A>

Parameters:

other - another Evaluable. Non null.

Specified by:

and in interface net.sf.staccatocommons.defs.predicate.Predicate<A>

Parameters:

other - another Evaluable. Non null.
