[description]
Clay introduces a method ensemble to both [class oo::class] and [class oo::object] called
clay. This ensemble handles all of the high level interactions within the framework.
Clay stores structured data. Clan manages method delegation. Clay has facilities to
manage the complex interactions that come about with mixins.
[para]
The central concept is that inside of every object and class
(which are actually objects too) is a dict called clay. What is stored in that dict is
left to the imagination. But because this dict is exposed via a public method, we can
share structured data between object, classes, and mixins.
[para]
[subsection {Structured Data}]
Clay uses a standardized set of method interactions and introspection that TclOO already provides to perform on-the-fly searches. On-the-fly searches mean that the data is never stale, and we avoid many of the sorts of collisions that would arise when objects start mixing in other classes during operation.
[para]
The [method clay] methods for both classes and objects have a get and a set method. For objects, get will search through the local clay dict. If the requested leaf is not found, or the query is for a branch, the system will then begin to poll the clay methods of all of the class that implements the object, all of that classes’ ancestors, as well as all of the classes that have been mixed into this object, and all of their ancestors.
[para]
Intended branches on a tree end with a directory slash (/). Intended leaves are left unadorned. This is a guide for the tool that builds the search
results to know what parts of a dict are intended to be branches and which are intended to be leaves.
For simple cases, branch marking can be ignored:
[example {
::oo::class create ::foo { }
::foo clay set property/ color blue
::foo clay set property/ shape round

set A [::foo new]
$A clay get property/
{color blue shape round}

$A clay set property/ shape square
$A clay get property/
{color blue shape square}
}]
[para]
But when you start storing blocks of text, guessing what field is a dict and what isn’t gets messy:
[example {
::foo clay set description {A generic thing of designated color and shape}

$A clay get description
{A generic thing of designated color and shape}

Without a convention for discerning branches for leaves what should have been a value can be accidentally parsed as a dictionary, and merged with all of the other values that were never intended to be merge. Here is an example of it all going wrong:
::oo::class create ::foo { }
# Add description as a leaf
::foo clay set description \
  {A generic thing of designated color and shape}
# Add description as a branch
::foo clay set description/ \
  {A generic thing of designated color and shape}

::oo::class create ::bar {
  superclass foo
}
# Add description as a leaf
::bar clay set description \
  {A drinking establishment of designated color and shape and size}
# Add description as a branch
::bar clay set description/ \
  {A drinking establishment of designated color and shape and size}

set B [::bar new]
# As a leaf we get the value verbatim from he nearest ancestor
$B clay get description
  {A drinking establishment of designated color and shape and size}
# As a branch we get a recursive merge
$B clay get description/
{A drinking establishment of designated color and size thing of}
}]
[subsection {Clay Dialect}]
Clay is built using the oo::dialect module from Tcllib. oo::dialect allows you to either add keywords directly to clay, or to create your own
metaclass and keyword set using Clay as a foundation. For details on the keywords and what they do, consult the functions in the ::clay::define namespace.
[subsection {Method Delegation}]
Method Delegation
It is sometimes useful to have an external object that can be invoked as if it were a method of the object. Clay provides a delegate ensemble method to perform that delegation, as well as introspect which methods are delegated in that manner. All delegated methods are marked with html-like tag markings (< >) around them.
[example {
::clay::define counter {
  Variable counter 0
  method incr {{howmuch 1}} {
    my variable counter
    incr counter $howmuch
  }
  method value {} {
    my variable counter
    return $counter
  }
  method reset {} {
    my variable counter
    set counter 0
  }
}
::clay::define example {
  variable buffer
  constructor {} {
    # Build a counter object
    set obj [namespace current]::counter
    ::counter create $obj
    # Delegate the counter
    my delegate <counter> $obj
  }

[call proc [cmd clay::define::Delegate] [arg name] [arg info]]

 An annotation that objects of this class interact with delegated
 methods. The annotation is intended to be a dictionary, and the
 only reserved key is [emph {description}], a human readable description.

[call proc [cmd clay::define::Dict] [arg name] [opt "[arg values] [const ""]"]]


[call proc [cmd clay::define::Option] [arg name] [opt "[arg args]"]]

 Define an option for the class




[call proc [cmd clay::define::Option_Class] [arg name] [opt "[arg args]"]]

 Define a class of options
 All field / value pairs will be be inherited by an option that
 specify [emph name] as it class field.




[call proc [cmd clay::define::Variable] [arg name] [opt "[arg default] [const ""]"]]

    This keyword can also be expressed:
    [example {property variable NAME {default DEFAULT}}]
    [para]
    Variables registered in the variable property are also initialized
    (if missing) when the object changes class via the [emph morph] method.

Return a complete dump of this object's clay data, but only this object's clay data.

[call method [cmd "clay find"] [arg path] [opt [option "path..."]]]

     Pull a chunk of data from the clay system. If the last element of [emph path] is a branch,
     returns a recursive merge of all data from this object and it's constituent classes of the data in that branch.
     If the last element is a leaf, search this object for a matching leaf, or search all  constituent classes for a matching
     leaf and return the first value found.
     If no value is found, returns an empty string.
     If a branch is returned the topmost . entry is omitted.
   

[call method [cmd "clay get"] [arg path] [opt [option "path..."]]]

     Pull a chunk of data from the class's clay system.
     If no value is found, returns an empty string.
     If a branch is returned the topmost . entry is omitted.
   

[call method [cmd "clay GET"] [arg path] [opt [option "path..."]]]

     Pull a chunk of data from the class's clay system.
     If no value is found, returns an empty string.
   

[call method [cmd "clay merge"] [arg dict] [opt [option "dict..."]]]
Recursively merge the dictionaries given into the object's local clay storage.

[call method [cmd "clay replace"] [arg dictionary]]
Replace the contents of the internal clay storage with the dictionary given.

[call method [cmd "clay search"] [arg path] [opt [option "path..."]]]
Return the first matching value for the path in either this class's clay data or one of its ancestors

[call method [cmd "clay set"] [arg path] [opt [option "path..."]] [arg value]]
Merge the conents of [const value] with the object's clay storage at [const path].

[call method [cmd "clay ancestors"]]
Return the class this object belongs to, all classes mixed into this object, and all ancestors of those classes in search order.

[call method [cmd "clay cget"] [arg field]]

 Pull a value from either the object's clay structure or one of its constituent classes that matches the field name.
 The order of search us:
 [para] 1. The as a value in local dict variable config
 [para] 2. The as a value in local dict variable clay
 [para] 3. As a leaf in any ancestor as a root of the clay tree
 [para] 4. As a leaf in any ancestor as [const const] [emph field]
 [para] 5. As a leaf in any ancestor as [const option] [emph field] [const default]
   

[call method [cmd "clay delegate"] [opt "[arg stub]"] [opt "[arg object]"]]

 Introspect or control method delegation. With no arguments, the method will return a
 key/value list of stubs and objects. With just the [arg stub] argument, the method will
 return the object (if any) attached to the stub. With a [arg stub] and an [arg object]
 this command will forward all calls to the method [arg stub] to the [arg object].
 

[call method [cmd "clay dump"]]
Return a complete dump of this object's clay data, as well as the data from all constituent classes recursively blended in.

[call method [cmd "clay ensemble_map"]]
Return a dictionary describing the method ensembles to be assembled for this object

[call method [cmd "clay eval"] [arg script]]
Evaluated a script in the namespace of this object

[call method [cmd "clay evolve"]]
Trigger the [method InitializePublic] private method

[call method [cmd "clay exists"] [arg path] [opt [option "path..."]]]
Returns 1 if [emph path] exists in either the object's clay data. Values greater than one indicate the element exists in one of the object's constituent classes. A value of zero indicates the path could not be found.

[call method [cmd "clay flush"]]
Wipe any caches built by the clay implementation

[call method [cmd "clay forward"] [arg method] [arg object]]
A convenience wrapper for
 [example {oo::objdefine [self] forward {*}$args}]
 

[call method [cmd "clay get"] [arg path] [opt [option "path..."]]]
Pull a chunk of data from the clay system. If the last element of [emph path] is a branch (ends in a slash /),
   returns a recursive merge of all data from this object and it's constituent classes of the data in that branch.
   If the last element is a leaf, search this object for a matching leaf, or search all  constituent classes for a matching
   leaf and return the first value found.
   If no value is found, returns an empty string.
 

[call method [cmd "clay leaf"] [arg path] [opt [option "path..."]]]
A modified get which is tailored to pull only leaf elements

[call method [cmd "clay merge"] [arg dict] [opt [option "dict..."]]]
Recursively merge the dictionaries given into the object's local clay storage.

[call method [cmd "clay mixin"] [arg class] [opt [option "class..."]]]

 Perform [lb]oo::objdefine [lb]self[rb] mixin[rb] on this object, with a few additional rules:
   Prior to the call, for any class was previously mixed in, but not in the new result, execute the script registered to mixin/ unmap-script (if given.)
   For all new classes, that were not present prior to this call, after the native TclOO mixin is invoked, execute the script registered to mixin/ map-script (if given.)
   Fall all classes that are now present and “mixed in”, execute the script registered to mixin/ react-script (if given.)
 

[call method [cmd "clay mixinmap"] [opt "[arg stub]"] [opt "[arg classes]"]]
With no arguments returns the map of stubs and classes mixed into the current object. When only stub is given,
  returns the classes mixed in on that stub. When stub and classlist given, replace the classes currently on that stub with the given
  classes and invoke clay mixin on the new matrix of mixed in classes.
 

[call method [cmd "clay provenance"] [arg path] [opt [option "path..."]]]
Return either [const self] if that path exists in the current object, or return the first class (if any) along the clay search path which contains that element.

[call method [cmd "clay replace"] [arg dictionary]]
Replace the contents of the internal clay storage with the dictionary given.

[call method [cmd "clay source"] [arg filename]]
Source the given filename within the object's namespace

[call method [cmd "clay set"] [arg path] [opt [option "path..."]] [arg value]]
Merge the conents of [const value] with the object's clay storage at [const path].

[call method [cmd "InitializePublic"]]

 Instantiate variables. Called on object creation and during clay mixin.
