Class Function

java.lang.Object
  pnuts.lang.Runtime
      pnuts.lang.Function

All Implemented Interfaces:

java.io.Serializable, Executable

public class Function
extends Runtime
implements java.io.Serializable

This class represents a function with a certain number of parameters. In Pnuts, functions should be accessed through PnutsFunction. This class is used mainly by compiler implementors. Note that there is no way to create a Function object through public API.
