Method Detail

applyAsInt

default int applyAsInt(long argument)

Applies this function to the given argument. Wraps any thrown checked exceptions with UncheckedException.

Specified by:

applyAsInt in interface java.util.function.LongToIntFunction

Since:

1.0

applyAsIntThrowing

int applyAsIntThrowing(long argument)
                throws java.lang.Exception

Applies this function to the given argument.

Throws:

java.lang.Exception

Since:

1.0

fallbackTo

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

Returns a LongToIntFunction applying the given function to the argument if this function throws an exception.

Throws:

java.lang.IllegalArgumentException - if fallback is null

Since:

1.0

fallbackTo

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

Returns a LongToIntFunction applying the given function to the argument if this function throws an exception.

Throws:

java.lang.IllegalArgumentException - if fallback is null

Since:

1.0

orReturn

default java.util.function.LongToIntFunction orReturn(int value)

Returns a LongToIntFunction returning the given value if this function throws an exception.

Since:

1.0

orReturn

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

Returns a LongToIntFunction returning the given value if this function throws an exception.

Since:

1.0

orThrow

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

Returns a ThrowingLongToIntFunction throwing an exception of the given type if this function throws an exception. The original exception thrown by this function 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 ThrowingLongToIntFunction orThrow(java.lang.Class<? extends java.lang.RuntimeException> exceptionClass,
                                          java.lang.String message)

Returns a ThrowingLongToIntFunction throwing an exception of the given type if this function throws an exception. The original exception thrown by this function 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 ThrowingLongToIntFunction orTryWith(ThrowingLongToIntFunction other)

Returns a ThrowingLongToIntFunction applying the given function to the argument if this function throws an exception.

Throws:

java.lang.IllegalArgumentException - if other is null

Since:

1.0

orTryWith

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

Returns a ThrowingLongToIntFunction applying the given function to the argument if this function throws an exception.
