java.util.function.DoublePredicate

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 ThrowingDoublePredicate
extends java.util.function.DoublePredicate

Represents a predicate (boolean-valued function) of one double-valued argument, possibly throwing an exception.

Method Detail

test

default boolean test(double argument)

Evaluates this predicate on the given argument. Wraps any thrown checked exceptions with UncheckedException.

Specified by:

test in interface java.util.function.DoublePredicate

Since:

1.0

testThrowing

boolean testThrowing(double argument)
              throws java.lang.Exception

Evaluates this predicate on the given argument.

Throws:

java.lang.Exception

Since:

1.0

fallbackTo

default java.util.function.DoublePredicate fallbackTo(java.util.function.DoublePredicate fallback)

Returns a DoublePredicate evaluating the given predicate on the argument if this predicate throws an exception.

Throws:

java.lang.IllegalArgumentException - if fallback is null

Since:

1.0

fallbackTo

default java.util.function.DoublePredicate fallbackTo(java.util.function.DoublePredicate fallback,
                                                      java.util.function.Consumer<java.lang.Exception> exceptionConsumer)

Returns a DoublePredicate evaluating the given predicate on the argument if this predicate throws an exception.

Throws:

java.lang.IllegalArgumentException - if fallback is null

Since:

1.0

orReturn

default java.util.function.DoublePredicate orReturn(boolean value)

Returns a DoublePredicate returning the given value if this predicate throws an exception.

Since:

1.0

orReturn

default java.util.function.DoublePredicate orReturn(boolean value,
                                                    java.util.function.Consumer<java.lang.Exception> exceptionConsumer)

Returns a DoublePredicate returning the given value if this predicate throws an exception.

Since:

1.0

orThrow

default ThrowingDoublePredicate orThrow(java.lang.Class<? extends java.lang.RuntimeException> exceptionClass)

Returns a ThrowingDoublePredicate throwing an exception of the given type if this predicate throws an exception. The original exception thrown by this predicate is the cause of the thrown exception.

The exception class must have a constructor accepting a single Throwable as an argument.

Throws:

java.lang.IllegalArgumentException - if exceptionClass is null

Since:

1.0

orThrow

default ThrowingDoublePredicate orThrow(java.lang.Class<? extends java.lang.RuntimeException> exceptionClass,
                                        java.lang.String message)

Returns a ThrowingDoublePredicate throwing an exception of the given type if this predicate throws an exception. The original exception thrown by this predicate is the cause of the thrown exception.

The exception class must have a constructor accepting String and Throwable as arguments.

Throws:

java.lang.IllegalArgumentException - if exceptionClass is null

Since:

1.0

orTryWith

default ThrowingDoublePredicate orTryWith(ThrowingDoublePredicate other)

Returns a ThrowingDoublePredicate evaluating the given predicate on the argument if this predicate throws an exception.

Throws:

java.lang.IllegalArgumentException - if other is null

Since:

1.0

orTryWith

default ThrowingDoublePredicate orTryWith(ThrowingDoublePredicate other,
                                          java.util.function.Consumer<java.lang.Exception> exceptionConsumer)

Returns a ThrowingDoublePredicate evaluating the given predicate on the argument if this predicate throws an exception.

Throws:

java.lang.IllegalArgumentException - if other is null

Since:

1.0
