Method Detail

applyAsInt

default int applyAsInt(T former,
                       U latter)

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

Specified by:

applyAsInt in interface java.util.function.ToIntBiFunction<T,U>

Since:

1.0

applyAsIntThrowing

int applyAsIntThrowing(T former,
                       U latter)
                throws java.lang.Exception

Applies this function to the given arguments.

Throws:

java.lang.Exception

Since:

1.0

fallbackTo

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

Returns a ToIntBiFunction 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.ToIntBiFunction<T,U> fallbackTo(java.util.function.ToIntBiFunction<T,U> fallback,
                                                           java.util.function.Consumer<java.lang.Exception> exceptionConsumer)

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

Throws:

java.lang.IllegalArgumentException - if fallback is null

Since:

1.0

orReturn

default java.util.function.ToIntBiFunction<T,U> orReturn(int value)

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

Since:

1.0

orReturn

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

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

Since:

1.0

orThrow

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

Returns a ThrowingToIntBiFunction 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
