Method Detail

memoize

public static <A,T> Function<A,T> memoize(Function<A,T> f)

Will transform the passed in Function in a apply once and only once Function. Irrespectively of the argument passed in! And isn't thread safe. Basically acts as a dumb cache.

Type Parameters:

A - the function's input param type

T - the function's output type

Parameters:

f - the function to memoize

Returns:

the memoized function

memoize

public static <A,B,T> BiFunction<A,B,T> memoize(BiFunction<A,B,T> f)

Will transform the passed in BiFunction in a apply once and only once BiFunction. Irrespectively of the arguments passed in! And isn't thread safe. Basically acts as a dumb cache.

Type Parameters:

A - the bifunction's first input param type

B - the bifunction's second input param type

T - the function's output type

Parameters:

f - the bifunction to memoize

Returns:

the memoized bifunction
