package ru.yandex.temp;

public abstract class Function1<A, B> {
	public abstract B apply(A a);
	
	/** (f andThen g)(x) = g(f(x)) */
	public <C> Function1<A, C> andThen(final Function1<B, C> g) {
		return new Function1<A, C>() {
			public C apply(A a) {
				return g.apply(Function1.this.apply(a));
			}
		};
	}
	
	/** (f compose g)(x) = f(g(x)) */
	public <C> Function1<C, B> compose(final Function1<C, A> g) {
		return g.andThen(this);
	}
}
