fallbackTo

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

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

java.lang.IllegalArgumentException - if fallback is null

Since:

1.0

orReturn

default java.util.function.DoubleToLongFunction orReturn(long value)

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

Since:

1.0

orReturn

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

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

Since:

1.0

orThrow

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

Returns a ThrowingDoubleToLongFunction 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
