Default visibility and modifiers for properties and methods

[Thomas.Schneider.Wien]

  Hello there,

   are the default visibility and modifiers specified somewhere by the
language itself,
or are those 'implementation dependent choices'.

    I cannot find an appropriate chapter in the NetRexx2 language
reference manual.


Example:

class myclass public
    a=int    -- note that there is NO preceeding properties statement
    b=Rexx ''

method mymethod(parm1=int 0, parm2=Rexx)
    ...

I did of course look at the NetRexxC generated code for this, but would
like to know whther the behaviour is
DEFINED somewhere in the language spec.

Tom.
PS: I do find the support of this 'compact syntax' very usefule and
hand! :-) Thanks, MFC :-)

Check out the PROPERTIES instruction (used to modify those attributes) and
in particular the paragraphs that start "By default ...".

(It's not spelled out elsewhere because the default is the typical usage.
Don't burden the readers with options until they need them.)

Thomas,

According to TNRL pg. 106:

"By default, if no properties instruction is used, or visibility is not specified, properties are inheritable (but not public)."

And in pg. 94:

"By default (i.e., if no visibility keyword is specified), methods are public."

So it is indeed specified :-)

Ah, but there's a foot note on page 106 of TNRL ;-)

44 The default, here waqs chosen to encourage the encapsulation of data within classes.

Yeah, that qualifies aa yet another feeble attempt at humour.. :-)
