Instance

public Instance(int arity,
                Function1<java.lang.Object[],R> function)

Constructs an instance of the function.

Parameters:

arity - the number of arguments of the function

function - the function to be applied

Method Detail

arity

public int arity()

Description copied from interface: FunctionN

Returns the number of arguments of the function. If used as a functional interface with a non-specific number of arguments, this will return -1.

Specified by:

arity in interface FunctionN<R>

Specified by:

arity in interface Arity

Returns:

the number of arguments of the function

applyAllUnchecked

public R applyAllUnchecked(java.lang.Object... args)

Description copied from interface: FunctionN

Applies this function to the given arguments. Makes no assumptions of the arguments passed in and whether a value will compute successfully.

Specified by:

applyAllUnchecked in interface FunctionN<R>

Parameters:

args - the function arguments

Returns:

the function result

andThen

public <V> FunctionN.Instance<V> andThen(Function1<? super R,? extends V> after)

Description copied from interface: ResultChainable

Returns a chained object that applies this chainable object, and then applies the after function to ths result. If evaluation of either throws an exception, it is relayed to the caller of the chained object.

Specified by:

andThen in interface FunctionN<R>

Specified by:

andThen in interface ResultChainable<R>

Specified by:

andThen in interface ResultChainableResult<R>

Type Parameters:

V - the type of the output of the after function, and of the chained object

Parameters:

after - the function to apply after this chainable object is applied

Returns:

a chained object that applies this chainable object and then applies the after function

andThenUnchecked

public <V> FunctionN.Instance<V> andThenUnchecked(Function1<? super R,? extends V> after)

Description copied from interface: ResultChainable

Returns a chained object that applies this chainable object, and then applies the after function to ths result. If evaluation of either throws an exception, it is relayed to the caller of the chained object. This makes no assumptions on the arguments of this method.

Specified by:

andThenUnchecked in interface FunctionN<R>

Specified by:

andThenUnchecked in interface ResultChainable<R>

Specified by:

andThenUnchecked in interface ResultChainableResult<R>

Type Parameters:

V - the type of the output of the after function, and of the chained object

Parameters:

after - the function to apply after this chainable object is applied

Returns:

a chained object that applies this chainable object and then applies the after function
