public class SubpImpl

extends SymImpl

implements Subp

Subp Class Subp (subprogram) class. Subprogram means such program construct as procedure, function, method, constructor, destructor, statement function, library function, etc. Each subprogram has its local symbol table which is maintained by pushSymbolTable, popSymbolTable, reopenSymbolTable in SymbolTableInterface. Enhancement is required to implement object oriented languages.

  setVisibility should be called if required and return value type
  should also be given if required.
  It is the responsibility of language dependent front end
  to check the consistency between prototype declaration and
  subprogram definition.
  Typical sequence of processing prototype declaration is:
    Subp lSubp = symRoot.sym.defineSubp("name".intern(), returnType);
    lSubp.resetParamTypeList(); // If multiple declaration is allowed.
    lSubp.addParamType(paramType1);
