Since:

1.0

apply

default R apply(T former,
                U latter)

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

Specified by:

apply in interface java.util.function.BiFunction<T,U,R>

Since:

1.0

applyThrowing

R applyThrowing(T former,

fallbackTo

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

Returns a BiFunction 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.BiFunction<T,U,R> fallbackTo(java.util.function.BiFunction<T,U,R> fallback,

orReturn

default java.util.function.BiFunction<T,U,R> orReturn(R value)

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

Since:

1.0

orReturn

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

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

Since:

1.0

orThrow

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

Returns a ThrowingBiFunction 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
