Interface DoubleIOPredicate

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface DoubleIOPredicate

Represents a predicate (boolean-valued function) of one double-valued argument. This is the IOException throwing equivalent of DoublePredicate.

Method Summary

Modifier and Type	Method and Description
default DoubleIOPredicate	and(DoubleIOPredicate other) Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
static DoubleIOPredicate	checked(DoublePredicate predicate) Returns a predicate that evaluates the predicate predicate, and unwraps any UncheckedIOException that is thrown by throwing its cause.
default DoubleIOPredicate	negate() Returns a predicate that represents the logical negation of this predicate.
default DoubleIOPredicate	or(DoubleIOPredicate other) Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.
boolean	test(double value) Evaluates this predicate on the given argument.
static DoublePredicate	unchecked(DoubleIOPredicate predicate) Returns a predicate that evaluates the predicate predicate, and wraps any IOException that is thrown in an UncheckedIOException.

Method Detail

test

boolean test(double value)
      throws IOException

Evaluates this predicate on the given argument.

Parameters:

value - The input argument.

Returns:

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

Throws:

IOException - If an I/O error occurs.

and

default DoubleIOPredicate and(DoubleIOPredicate 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 - A predicate that will be logically-ANDed with this predicate.

Returns:

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

Throws:

NullPointerException - If other is null.

negate

default DoubleIOPredicate negate()

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

Returns:

A predicate that represents the logical negation of this predicate.

or

default DoubleIOPredicate or(DoubleIOPredicate 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 - A predicate that will be logically-ORed with this predicate.

Returns:

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

Throws:

NullPointerException - If other is null.

unchecked

static DoublePredicate unchecked(DoubleIOPredicate predicate)

Returns a predicate that evaluates the predicate predicate, and wraps any IOException that is thrown in an UncheckedIOException.

Parameters:

predicate - The predicate to evaluate when the returned predicate is evaluated.

Returns:

A predicate that evaluates the predicate predicate on its input, and wraps any IOException that is thrown in an UncheckedIOException.

Throws:

NullPointerException - If predicate is null.

checked

static DoubleIOPredicate checked(DoublePredicate predicate)

Returns a predicate that evaluates the predicate predicate, and unwraps any UncheckedIOException that is thrown by throwing its cause.

Parameters:

predicate - The predicate to evaluate when the returned predicate is evaluated.

Returns:

A predicate that evaluates the predicate operation on its input, and unwraps any UncheckedIOException that is thrown.

Throws:

NullPointerException - If the given operation is null.
