Specified by:

applyAsLong in interface java.util.function.ToLongBiFunction<T,U>

Since:

1.0

applyAsLongThrowing

long applyAsLongThrowing(T former,
                         U latter)
                  throws java.lang.Exception

Applies this function to the given arguments.

Throws:

java.lang.Exception

Since:

fallbackTo

default java.util.function.ToLongBiFunction<T,U> fallbackTo(java.util.function.ToLongBiFunction<T,U> fallback)

Returns a ToLongBiFunction applying the given function to the arguments if this function throws an exception.

Throws:

java.lang.IllegalArgumentException - if fallback is null

Since:

1.0

fallbackTo

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

Since:

1.0

orReturn

default java.util.function.ToLongBiFunction<T,U> orReturn(long value)

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

Since:

1.0

orReturn

default java.util.function.ToLongBiFunction<T,U> orReturn(long value,
                                                          java.util.function.Consumer<java.lang.Exception> exceptionConsumer)

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

Since:

1.0

orThrow

default ThrowingToLongBiFunction<T,U> orThrow(java.lang.Class<? extends java.lang.RuntimeException> exceptionClass)

Returns a ThrowingToLongBiFunction 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.
