Interface BooleanSupplierWithThrowable<E extends Throwable>

Type Parameters:

E - The extension

All Superinterfaces:

BooleanSupplier

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 BooleanSupplierWithThrowable<E extends Throwable>
extends BooleanSupplier

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

Method Detail

castBooleanSupplierWithThrowable

static <E extends Throwable> BooleanSupplierWithThrowable<E> castBooleanSupplierWithThrowable(BooleanSupplierWithThrowable<E> booleansupplierwiththrowable)

Utility method to mark lambdas of type BooleanSupplierWithThrowable

Type Parameters:

E - The type this interface is allowed to throw

Parameters:

booleansupplierwiththrowable - The interface instance

Returns:

the cast interface

aBooleanSupplierThatUnsafelyThrowsUnchecked

static <E extends Throwable> BooleanSupplier aBooleanSupplierThatUnsafelyThrowsUnchecked(BooleanSupplierWithThrowable<E> booleansupplierwiththrowable)
                                                                                  throws E extends Throwable

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

Type Parameters:

E - The type this interface is allowed to throw

Parameters:

booleansupplierwiththrowable - The interface instance

Returns:

the cast interface

Throws:

E - the original Exception from booleansupplierwiththrowable

E extends Throwable

asBooleanSupplierWithThrowable

static <E extends Throwable> BooleanSupplierWithThrowable<E> asBooleanSupplierWithThrowable(BooleanSupplier booleansupplier)

Utility method to convert BooleanSupplierWithThrowable

Type Parameters:

E - The type this interface is allowed to throw

Parameters:

booleansupplier - The interface instance

Returns:

the cast interface

getAsBoolean

default boolean getAsBoolean()

Overridden method of BooleanSupplierWithThrowable that will call getAsBooleanWithThrowable, but catching any exceptions.

Specified by:

getAsBoolean in interface BooleanSupplier

Returns:

the value

getAsBooleanWithThrowable

boolean getAsBooleanWithThrowable()
                           throws E extends Throwable

Functional method that will throw exceptions.

Returns:

the value

Throws:

E - some exception

E extends Throwable

thatReturnsOnCatch

default BooleanSupplier 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 BooleanSupplier 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 BooleanSupplierWithThrowable<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 BooleanSupplierWithThrowable<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 BooleanSupplierWithThrowable<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 BooleanSupplierWithThrowable<E> onException(Consumer<Throwable> consumer)

Parameters:

consumer - An exception consumer.

Returns:

An interface that will log all exceptions to given logger
