Interface Function3<A,B,C,D>

Type Parameters:

A - function first argument type

B - function second argument type

C - function return type

All Superinterfaces:

Applicable<A,Function2<B,C,D>>, Applicable2<A,B,Function<C,D>>, Applicable3<A,B,C,D>, Delayable3<A,B,C,D>, NullSafeAware<Function3<A,B,C,D>>

@Applicative
public interface Function3<A,B,C,D>
extends Applicable3<A,B,C,D>, Applicable2<A,B,Function<C,D>>, Applicable<A,Function2<B,C,D>>, NullSafeAware<Function3<A,B,C,D>>, Delayable3<A,B,C,D>

Function3s are rich interfaced Applicable3s - two arguments Delayable3 and NullSafeAware transformations. Function3 can also be partially applied, which means, applying it with less arguments than required, returning, instead of the result of the transformation, a new function that expects the rest of the arguments. Thus, Function3 do also implement Applicable and Applicable2

Method Summary

Function2<B,C,D>	apply(A arg0) Partially applies the function, passing only its first argument
Function<C,D>	apply(A arg0, B arg1) Partially applies the function, passing only its first and second arguments
D	apply(A arg0, B arg1, C arg2) Performs a transformation on the given element, and returns its result.
Function3<A,B,C,D>	nullSafe() Answers a new function that returns null if any of its arguments is null, or the result of applying this function, otherwise.
Function<Tuple3<A,B,C>,D>	uncurry() Uncurries this function, by returning a Function that takes a single triple, being its components each of the original function parameters

Method Detail

apply

Function2<B,C,D> apply(A arg0)

Partially applies the function, passing only its first argument

Specified by:

apply in interface Applicable<A,Function2<B,C,D>>

Parameters:

arg0 - the transformation

Returns:

the transformation result

apply

Function<C,D> apply(A arg0,
                    B arg1)

Partially applies the function, passing only its first and second arguments

Specified by:

apply in interface Applicable2<A,B,Function<C,D>>

Parameters:

arg0 - the first transformation argument

arg1 - the second transformation argument

Returns:

the transformation result

apply

D apply(A arg0,
        B arg1,
        C arg2)

Description copied from interface: Applicable3

Performs a transformation on the given element, and returns its result.

Specified by:

apply in interface Applicable3<A,B,C,D>

Parameters:

arg0 - the first transformation argument

arg1 - the second transformation argument

arg2 - the third transformation argument

Returns:

the transformation result

nullSafe

@NullSafe
Function3<A,B,C,D> nullSafe()

Answers a new function that returns null if any of its arguments is null, or the result of applying this function, otherwise.

Specified by:

nullSafe in interface NullSafeAware<Function3<A,B,C,D>>

Returns:

a new null-safe Function3

uncurry

Function<Tuple3<A,B,C>,D> uncurry()

Uncurries this function, by returning a Function that takes a single triple, being its components each of the original function parameters

Returns:

a new Function
