SYNOPSIS

#include "<SOS>/include/mta_sos.h"

class sos_Method_table 
  : Mapping <sos_String, List <sos_Method>> (FALSE, TRUE, FALSE)
{
public:
  sos_Method      lookup (sos_Method);
  sos_Method      lookup_or_add (sos_Method);  
  sos_Method      replace_or_add (sos_Method);

  sos_Comp_method lookup_comp (sos_String, sos_Bool);
};

DESCRIPTION

sos_Method_table provides access on method-lists containing methods of a specified name.

lookup (m)

returns the first method from the method list associated with the name of m, which does not overload m. The return value is NO_OBJECT, if no such method can be found. Only some of the parameters of m have to be specified: the method name and a parameter list which has at least the correct cardinality. The returned method will in general not conform to the method signature described by m (the method will have the same number of parameters, or m and the method will not be both static or non-static). Conformance can be checked by sos_Method::redefines(...) (note, that m must be fully specified for this call).

lookup_or_add (m)

If lookup(m) finds an appropriate method, this is returned. Otherwise, if there exists an entry in the table for the method name, m is appended on the associated list. If no entry exists, a new method list is created, m is inserted in this list, and the list is inserted in the method table.

replace_or_add (m)

If lookup(m) finds an appropriate method, this is replaced by m. Otherwise, if there exists an entry in the table for the method name, m is appended on the associated list. If no entry exists, a new method list is created, m is inserted in this list, and the list is inserted in the method table.

lookup_comp (s, is)

yields the first component method setting (if is==TRUE) or getting (if is==FALSE) a component named s.
