Summary

Public methods

default DoublePredicate and(DoublePredicate other)

Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.

default DoublePredicate negate()

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

default DoublePredicate or(DoublePredicate other)

Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.

abstract boolean test(double value)

Evaluates this predicate on the given argument.

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
Throws
NullPointerException if other is null

negate

Added in API level 24
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

or

Added in API level 24
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
Throws
NullPointerException if other is null

test

Added in API level 24
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

Hooray!
