Constructor Detail

Composite

public Composite()

Composite instances should NOT be constructed in standard programming. Instead, the methods of the class should be invoked statically.

This constructor is public to permit tools that require a JavaBean instance to operate.

Method Detail

procedure

public static <A> CompositeUnaryProcedure<A> procedure(UnaryProcedure<? super A> procedure)

Create a composite UnaryProcedure.

Parameters:

procedure - UnaryProcedure to execute against output of f

Returns:

CompositeUnaryProcedure
