Interface PredicateWithThrowable<T,E extends Throwable>

Type Parameters:

T - some generic flag

E - The extension

All Superinterfaces:

Predicate<T>

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 PredicateWithThrowable<T,E extends Throwable>
extends Predicate<T>

Generated from Predicate Extends java.util.function.Predicate to allow for a checked exception.

Method Detail

castPredicateWithThrowable

static <T,E extends Throwable> PredicateWithThrowable<T,E> castPredicateWithThrowable(PredicateWithThrowable<T,E> predicatewiththrowable)

Utility method to mark lambdas of type PredicateWithThrowable

Type Parameters:

T - Generic that corresponds to the same generic on Predicate

E - The type this interface is allowed to throw

Parameters:

predicatewiththrowable - The interface instance

Returns:

the cast interface

aPredicateThatUnsafelyThrowsUnchecked

static <T,E extends Throwable> Predicate<T> aPredicateThatUnsafelyThrowsUnchecked(PredicateWithThrowable<T,E> predicatewiththrowable)
                                                                           throws E extends Throwable

Utility method to unwrap lambdas of type Predicate and withUncheckedThrowable any Exception

Type Parameters:

T - Generic that corresponds to the same generic on Predicate

E - The type this interface is allowed to throw

Parameters:

predicatewiththrowable - The interface instance

Returns:

the cast interface

Throws:

E - the original Exception from predicatewiththrowable

E extends Throwable

asPredicateWithThrowable

static <T,E extends Throwable> PredicateWithThrowable<T,E> asPredicateWithThrowable(Predicate<T> predicate)

Utility method to convert PredicateWithThrowable

Type Parameters:

T - Generic that corresponds to the same generic on Predicate

E - The type this interface is allowed to throw

Parameters:

predicate - The interface instance

Returns:

the cast interface

test

default boolean test(T v1)

Overridden method of PredicateWithThrowable that will call testWithThrowable, but catching any exceptions.

Specified by:

test in interface Predicate<T>

Parameters:

v1 - parameter to overridden method

Returns:

the value

testWithThrowable

boolean testWithThrowable(T v1)
                   throws E extends Throwable

Functional method that will throw exceptions.

Parameters:

v1 - parameter to overridden method

Returns:

the value

Throws:

E - some exception

E extends Throwable

thatReturnsOnCatch

default Predicate<T> thatReturnsOnCatch(boolean defaultReturnValue)

Parameters:

defaultReturnValue - A value to return if any throwable is caught.

Returns:

An interface that returns a default value if any exception occurs.

thatUnsafelyThrowsUnchecked

default Predicate<T> thatUnsafelyThrowsUnchecked()
                                          throws E extends Throwable

Returns:

An interface that is only returned if no exception has been thrown.

Throws:

E - if an exception E has been thrown, it is rethrown by this method

E extends Throwable

withLogging

default PredicateWithThrowable<T,E> withLogging(org.slf4j.Logger logger,
                                                String message)

Parameters:

logger - The logger to log exceptions on

message - A message to use for logging exceptions

Returns:

An interface that will log all exceptions to given logger

withLogging

default PredicateWithThrowable<T,E> withLogging(org.slf4j.Logger logger)

Will log WARNING level exceptions on logger if they occur within the interface

Parameters:

logger - The logger instance to log exceptions on

Returns:

An interface that will log exceptions on given logger

withLogging

default PredicateWithThrowable<T,E> withLogging()

Will log WARNING level exceptions on logger if they occur within the interface

Returns:

An interface that will log exceptions on global logger

onException

default PredicateWithThrowable<T,E> onException(Consumer<Throwable> consumer)

Parameters:

consumer - An exception consumer.

Returns:

An interface that will log all exceptions to given logger

onException

default PredicateWithThrowable<T,E> onException(BiConsumer<Throwable,Object[]> consumer)

Parameters:

consumer - An exception consumer.

Returns:

An interface that will log all exceptions to given logger
