public class GenericProc extends MethodProc
A collection of MethodProcs; one is chosen at apply time.

    • getMethod

      public MethodProc getMethod(int i)

    • numArgs

      public int numArgs()
      Description copied from class: Procedure
      Return minArgs()|(maxArgs<<12). We use a single virtual function to reduce the number of methods in the system, as well as the number of virtual method table entries. We shift by 12 so the number can normally be represented using a sipush instruction, without requiring a constant pool entry.
      Overrides:
      numArgs in class Procedure

    • addAll

      protected void addAll(MethodProc[] procs)

    • addAtEnd

      public void addAtEnd(MethodProc method)

    • add

      public void add(MethodProc method)

    • isApplicable

      public int isApplicable(Type[] args, Type restType)
      Description copied from class: MethodProc
      Test if method is applicable to an invocation with given arguments.
      Overrides:
      isApplicable in class MethodProc
      Parameters:
      args - array of known "single" arguments.
      restType - If null, the arguments are fully specified by argTypes. If non-null, there may be an unknown number of extra arguments of the given restType. This is used for splices, where we usually don't know at compile-time how many argument values we have.
      Returns:
      -1 if no; 1 if yes; 0 if need to check at run-time.

    • applyToConsumerGP

      public static Object applyToConsumerGP(Procedure proc, CallContext ctx) throws Throwable
