Method Detail

applyAsDouble

default double applyAsDouble(int argument)

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

Specified by:

applyAsDouble in interface java.util.function.IntToDoubleFunction

Since:

1.0

applyAsDoubleThrowing

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

Applies this function to the given argument.

Throws:

java.lang.Exception

Since:

1.0

fallbackTo

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

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

Returns an IntToDoubleFunction 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.IntToDoubleFunction orReturn(double value)

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

Since:

1.0

orReturn

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

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

Since:

1.0

orThrow

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

Returns a ThrowingIntToDoubleFunction 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 ThrowingIntToDoubleFunction orThrow(java.lang.Class<? extends java.lang.RuntimeException> exceptionClass,
                                            java.lang.String message)

Returns a ThrowingIntToDoubleFunction 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 ThrowingIntToDoubleFunction orTryWith(ThrowingIntToDoubleFunction other)

Returns a ThrowingIntToDoubleFunction 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 ThrowingIntToDoubleFunction orTryWith(ThrowingIntToDoubleFunction other,
                                              java.util.function.Consumer<java.lang.Exception> exceptionConsumer)

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