Method Detail

applyAsLong

default long applyAsLong(T argument)

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

Specified by:

applyAsLong in interface java.util.function.ToLongFunction<T>

Since:

applyAsLongThrowing

long applyAsLongThrowing(T argument)
                  throws java.lang.Exception

Applies this function to the given argument.

Throws:

java.lang.Exception

Since:

1.0

fallbackTo

default java.util.function.ToLongFunction<T> fallbackTo(java.util.function.ToLongFunction<T> fallback)

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

Returns a ToLongFunction 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.ToLongFunction<T> orReturn(long value)

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

Since:

1.0

orReturn

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

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

Since:

1.0

orThrow

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

Returns a ThrowingToLongFunction 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 ThrowingToLongFunction<T> orThrow(java.lang.Class<? extends java.lang.RuntimeException> exceptionClass,

Returns a ThrowingToLongFunction 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

Returns a ThrowingToLongFunction 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 ThrowingToLongFunction<T> orTryWith(ThrowingToLongFunction<? super T> other,
