shouldCallSuperMethod
package metaobjectTest
@doc{*
Metaobject 'shouldCallSuperMethod' is an action function. Its
associated metaobject declares a method 'eval' that may be
called by other metaobjects. It cannot be associated to
an annotation:
// compile-time error
@shouldCallSuperMethod
This action function can be called by method 'call:' of
Myan or Tyan (interpreted Cyan) or by the following
statements:
WrEnv env = compiler.getEnv();
IActionFunction f = env.searchActionFunction("shouldCallSuperMethod");
f.eval(input);
'input' is a saci.Tuple6 (saci is a Cyan Compiler package) whose elements
are:
- the compiler passed as parameter to a metaobject method
- the metaobject
- the list of annotation parameters
- a symbol to be used if there is an error
- the current method
- the environment
All of these parameters are automatically passed when using method
'call:' of Myan or Tyan, as in the example of annotation 'onOverride'
below.
