Method Details

bindParameter

public static <A,
B,
R> Function<B,R> bindParameter(BiFunction<A,B,R> f,
 A a)

It partially applies function A. In other words, it converts a 2 argument function to a 1 argument function by binding the first argument to a. Here you can see an example:

 {@code BiFunction<Int, Int, Int> adder = (x, y) -> x + y;
   Function<Int, Int> add5 = bindParameter(adder, 5);
   add5(1);
 }
 

Parameters:

f - the function to partially apply

a - the first parameter to partially apply

Returns:

the function partially applied
