Property reform part 1:

- disallow protection modifiers for "properties" and

add new flag "-accessor" to "property" and "variable"

This changes definitions like

Class create C {

:property {a a1}

:public property {b b1}

:protected property {c c1}

:private property {d d1}

}

to

Class create C {

:property {a a1}

:property -accessor public {b b1}

:property -accessor protected {c c1}

:property -accessor private {d d1}

}

since "properties" are always public accessible

over the "configure" and "cget" interface, but the

accessors methods might not be public. The value of

the accessor might be also "none" (specifying explicitely

that no accessor is wanted) or "", which means: use the default.

Same holds for "variable"

- disallow parameter option "incremental" and change it to a flag

of the property or variable. The motivation for this is due to

the fact, that "incremental" is a property of the accessor, and

not of the value.

old:

Class create C {

:property foo:int,incremental

:variable bar:int,incremental

}

new:

Class create C {

:property -incremental foo:int

:variable -incremental bar:int

}

- disallow "public class property" and friends since these are not needed

- removed parameter property "noaccessor"

- removed "nx::configure defaultPropertyCallProtection" and

method hook "__default_property_call_protection"

- introduced "nx::configure defaultAccessor" and

method hook "__default_accessor"

- for the time being, "defaultAccessor" is "public" for NX and XOTcl,

will be changed to "none" in NX

- extended regression test (new file properties.test)

nx.tcl: - remove debugging output

nsf.c: - made argument of cget required

nx.tcl:

- added Tk-style methods "configure" and "cget"

- added additional regression test set for cget and configure

nsf.c: - implememted cget as a configure-like method, dropped ensemble method variant

nx.tcl:

- simplified "/obj|cls/ delete method" due to resolving capabilities in

nsf::delete::method

nsf.c: - extended nsf::method::delete to handle ensemble names

nx.tcl:

- added tk/incr-tcl style cget methods on class/object levels.

- improve copy handling with other child-types of the slot container working

- make sure to ignore non-slot-type objects in slot introspection

- worked on regression test until "methods.test". others are missing,

but maybe reconsideration

nx.tcl: - rename the following internally called methods (not for XOTcl). alloc -> __alloc dealloc -> __dealloc objectparameter -> __objectparameter recrate -> __recreate - from these methods, only __objectparameter is defined per default, the others are defined on demand

- rename nx::Object.configure to nx::Object.__configure to free method name "configure" for an e.g. tk-like configure

Interim commit

Reintroduce forValueCheck

- use "nsf::relation $cl superclass" instead of "$cl configure -superclass"

nx.tcl: - set multiplicty for mixins and filters by default from 1..n to 0..n to avoid error messages, when e.g. empty mixin lists are configured. Setting emtpy mixin-lists is strictly speaking not necessary, but this eases the code in cases the lists are sometimes empty.

Adding a test case and a preliminary fix for the parameter option interactions

- library/nx/nx.tcl: Following the code review, implemented a first scheme for handling traces in setCheckedInstVar. This gives us consistent behavior for defaults and traces (valuechangedcmd) across classes and objects. - tests/parameters.test: Adjusted the relevant tests - Pending: setCheckedInstVar currently uses ::nsf::is to validate the value (e.g., default value) to be set. However, it might get passed parameter options which do not fit the NSF_DISALLOWED_ARG_VALUECHECKED filter.

- honor default type in "info slot names"

- Addressed a number of issues in the NX slot infrastructure (which revealed themselves when running Mark's BusinessActivities implementation in XOTcl2 mode): - generic/nsf.c: Initcmd blocks (as set for registering per-class slot traces) were subjected to argument checks causing unexpected behavior (e.g., attempts of unboxing initcmds as Tcl lists or of checking initcmds against value types). This was fixed by exempting NSF_ARG_INITCMD params from argument checking in ArgumentCheck() explicitly. - library/nx/nx.tcl: For per-class parameters, the use of valuechangedcmd effectively overruled the default value specified (simply because the generated initcmd holding the trace statements took the place of the default value). While for defaultcmd and for valuecmd the parallel use of default is forbidden, the valuechangedcmd semantics allow for specifying a default, in principle. This was fixed by providing a default-setting statement in the initcmd. - tests/parameters.test: Added tests to cover the above (and beyond). - library/xotcl/library/xotcl2.tcl: Extended the backwards compatibility of the hybrid XOTcl2/NX slots infrastructure to the XOTcl 1 interface: This includes support for inline -proc statements and instvar. This compat level corresponds to the slot interface as documented (by examples) in the XOTcl language ref and the manual. - library/xotcl/tests/slottest.xotcl: Added tests for the above compat enhancements.

- added "private property foo" - extended regression test

nsf.c: - added object parameter option "slotinitialize" - renamed object parameter option "invokesetter" -> "slotassign" - call slot.assign instead of setter of object - removed restriction on nosetter/invokesetter: nosetter can be used in connection with slotassign - added regression test for slot.initialize

- additional object parameter option "invokesetter" managed by nx.tcl This was necessary, since the previously implemented strategy called the setter whenever slot= was provided. This has the problem, that values could be converted twice (once by "configure", once by the setter method", which lead for the converter to a double refcounting on the value.

- make clear that "pattern" is an optional argument of "info lookup method" - make clear, that 'all' is a permissible value for nonpos arg "-callprotection" (several commands)

- Forward setting of object parameters to the slot object, when assign method is user-defined on the slot object - Cleanup and extend regression test

- fixed potential crash from method caching, when permissions on cmds are changed and become e.g. unresolvable - removed flag allowmethoddispatch, since behavior can be achived via private flag. - extended regression test
