applyN

public Object applyN(Object[] args)

Overrides:

applyN in class Procedure

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
