fallbackTo

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

Returns an IntToLongFunction 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.IntToLongFunction fallbackTo(java.util.function.IntToLongFunction fallback,
                                                        java.util.function.Consumer<java.lang.Exception> exceptionConsumer)

Returns an IntToLongFunction 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.IntToLongFunction orReturn(long value)

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

Since:

1.0

orReturn

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

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

Since:

1.0

orThrow

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

Returns a ThrowingIntToLongFunction 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
