Methods

and(FailableDoublePredicate)	Returns a composed FailableDoublePredicate like DoublePredicate#and(DoublePredicate).
falsePredicate()	Gets the FALSE singleton.
negate()	Returns a predicate that negates this predicate.
or(FailableDoublePredicate)	Returns a composed FailableDoublePredicate like DoublePredicate#and(DoublePredicate).
test(double)	Tests the predicate.
truePredicate()	Gets the TRUE singleton.

public default FailableDoublePredicate<E> and(FailableDoublePredicate<E> other)

Returns a composed FailableDoublePredicate like DoublePredicate#and(DoublePredicate).

Parameters:

other – A predicate that will be logically-ANDed with this predicate.

Returns:

A composed FailableDoublePredicate like DoublePredicate#and(DoublePredicate).

Throws:

java.lang.NullPointerException – Thrown if other is null.

@SuppressWarnings({"unchecked"}) public static <E extends Throwable> FailableDoublePredicate<E> falsePredicate()

Gets the FALSE singleton.

Type parameters:

<E> – The kind of thrown exception or error.

Returns:

The NOP singleton.

public default FailableDoublePredicate<E> negate()

Returns a predicate that negates this predicate.

Returns:

A predicate that negates this predicate.

public default FailableDoublePredicate<E> or(FailableDoublePredicate<E> other)

Returns a composed FailableDoublePredicate like DoublePredicate#and(DoublePredicate).

Parameters:

other – A predicate that will be logically-ORed with this predicate.

Returns:

A composed FailableDoublePredicate like DoublePredicate#and(DoublePredicate).

Throws:

java.lang.NullPointerException – Thrown if other is null.

public abstract boolean test(double value) throws E

Tests the predicate.

Parameters:

value – The parameter for the predicate to accept.

Returns:

true if the input argument matches the predicate, false otherwise.

Throws:

E – Thrown when the consumer fails.

@SuppressWarnings({"unchecked"}) public static <E extends Throwable> FailableDoublePredicate<E> truePredicate()

Gets the TRUE singleton.

Type parameters:

<E> – The kind of thrown exception or error.

Returns:

The NOP singleton.
