public class ModuleMethod

extends ProcedureN

Call a specified method in in a ModuleBody. We use an extra level of indirection, but we save by having to create fewer classes than in the one-class-per-procedure scheme, without having to use (slow) reflection. ModuleMethod is redundant, since it could be replaced by ApplyMethodProc. However, ModuleMethod uses virtual method calls, while ApplyMethodProc uses the possibly much slower interface method calls.
