Method Detail

andback to summary
public default DoublePredicate and(DoublePredicate other)

Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another. When evaluating the composed predicate, if this predicate is false, then the other predicate is not evaluated.

Any exceptions thrown during evaluation of either predicate are relayed to the caller; if evaluation of this predicate throws an exception, the other predicate will not be evaluated.

Parameters
other:DoublePredicate

a predicate that will be logically-ANDed with this predicate

Returns:DoublePredicate

a composed predicate that represents the short-circuiting logical AND of this predicate and the other predicate

Exceptions
NullPointerException:
if other is null
negateback to summary
public default DoublePredicate negate()

Returns a predicate that represents the logical negation of this predicate.

Returns:DoublePredicate

a predicate that represents the logical negation of this predicate

orback to summary
public default DoublePredicate or(DoublePredicate other)

Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another. When evaluating the composed predicate, if this predicate is true, then the other predicate is not evaluated.

Any exceptions thrown during evaluation of either predicate are relayed to the caller; if evaluation of this predicate throws an exception, the other predicate will not be evaluated.

Parameters
other:DoublePredicate

a predicate that will be logically-ORed with this predicate

Returns:DoublePredicate

a composed predicate that represents the short-circuiting logical OR of this predicate and the other predicate

Exceptions
NullPointerException:
if other is null
testback to summary
public boolean test(double value)

Evaluates this predicate on the given argument.

Parameters
value:double

the input argument

Returns:boolean

true if the input argument matches the predicate, otherwise false
