Method Detail

applyAsDouble

default double applyAsDouble(long argument)

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

Specified by:

applyAsDouble in interface java.util.function.LongToDoubleFunction

Since:

1.0

applyAsDoubleThrowing

double applyAsDoubleThrowing(long argument)
                      throws java.lang.Exception

Applies this function to the given argument.

Throws:

java.lang.Exception

Since:

1.0

fallbackTo

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

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

Returns a LongToDoubleFunction 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.LongToDoubleFunction orReturn(double value)

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

Since:

1.0

orReturn

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

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

Since:

1.0

orThrow

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

Returns a ThrowingLongToDoubleFunction 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

default ThrowingLongToDoubleFunction orThrow(java.lang.Class<? extends java.lang.RuntimeException> exceptionClass,
                                             java.lang.String message)

Returns a ThrowingLongToDoubleFunction 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 String and Throwable as arguments.

Throws:

java.lang.IllegalArgumentException - if exceptionClass is null

Since:

1.0

orTryWith

default ThrowingLongToDoubleFunction orTryWith(ThrowingLongToDoubleFunction other)

Returns a ThrowingLongToDoubleFunction applying the given function to the argument if this function throws an exception.

Throws:

java.lang.IllegalArgumentException - if other is null

Since:

1.0

orTryWith

default ThrowingLongToDoubleFunction orTryWith(ThrowingLongToDoubleFunction other,
