TYPE VARIABLES
Snit_info Introspection Array. Keys and values are as
follows:
hasinstances Boolean. Normally T, but F if pragma -hasinstances no
simpledispatch Uses a very simple method dispatcher.
canreplace Boolean. Normally F, but T if pragma -canreplace yes
counter Integer counter. Used to generate unique names.
widgetclass Tk widget class name for snit::widgets
hulltype Hull widget type (frame or toplevel) for
snit::widgets.
ns The type namespace, "$type::". UNUSED.
exceptmethods Method names excluded from delegate method *.
excepttypemethods Typemethod names excluded from delegate typemethod *.
tvardecs Type variable declarations--for dynamic
methods.
ivardecs Instance variable declarations--for dynamic
methods.
isWidget Boolean; true if object is a widget or
widgetadaptor.
isWidgetAdaptor Boolean; true if object is a widgetadaptor
Snit_methods List of method names; defined only when
-simpledispatch yes.
Snit_typemethodInfo Array(method name) = {<flag> ?<pattern> <compName>?}
where <flag> is 1 if the method has submethods
(in which case the other fields
are missing) and 0 if it doesn't.
<compName> is "" for normal typemethods
and "method name" can be "*". Used in
typemethod cache lookup to create the command
for the named typemethod.
Snit_typecomponents Array(typecomponent name) = command_name
Used whenever we need to retrieve the
typecomponent's command.
Snit_typeMethodCache Array(typemethod name) = cached command
Used in typemethod dispatch.
Snit_methodInfo Array(method name) = {<flag> ?<pattern> <compName>?}
where <flag> is 1 if the method has submethods
(in which case the other fields
are missing) and 0 if it doesn't.
<compName> is "" for normal methods and
"method name" can be "*". Used in
method cache lookup to create the command for
the named method.
Snit_optionInfo An array of option data. The keys are as follows:
General fields:
local List of local option names.
delegated List of explicitly delegated option names.
starcomp Name of component for "delegate option *" or ""
except List of option names explicitly NOT delegated
by "delegate option *".
Fields defined for all locally defined and explicitly delegated options:
islocal-$opt 1 if local, 0 otherwise.
resource-$opt The option's resource name.
class-$opt The option's class name.
Fields defined only for locally defined options
default-$localOpt Default value.
validate-$localOpt The name of the validate method, or "".
configure-$localOpt The name of the configure method, or "".
cget-$localOpt The name of the cget method, or "".
readonly-$localOpt true or false. (false is the default).
Fields defined only for delegated options
delegated-$comp List of option names delegated to this component.
target-$opt [list component targetOptionName].
INSTANCE VARIABLES
Snit_iinfo Array, instance info. At some point,
Snit_instance and Snit_components should
probably be consolidated into it. The fields
are:
constructed 0 during instance construction, and 1 after.
Snit_instance Current name of the instance command.
Snit_components Array(component name) = command_name
Used whenever we need to retrieve the
component's command.
Consider consolidating the following arrays into a single array, since
they are all cleared at the same time.
Snit_methodCache Array(method name) = cached command
Used during method dispatch.
Snit_cgetCache Array(option name) = cached command.
Used by $self cget.
Snit_configureCache Array(option name) = cached command.
Used by $self configurelist.
Snit_validateCache Array(option name) = cached command.
Used by $self configurelist. The entry is ""
if there is no validate command.
