"aetypes" --- AppleEvent objects
********************************

The "aetypes" defines classes used to represent Apple Event data
descriptors and Apple Event object specifiers.

Apple Event data is contained in descriptors, and these descriptors
are typed. For many descriptors the Python representation is simply
the corresponding Python type: "typeText" in OSA is a Python string,
"typeFloat" is a float, etc. For OSA types that have no direct Python
counterpart this module declares classes. Packing and unpacking
instances of these classes is handled automatically by "aepack".

An object specifier is essentially an address of an object implemented
in a Apple Event server. An Apple Event specifier is used as the
direct object for an Apple Event or as the argument of an optional
parameter. The "aetypes" module contains the base classes for OSA
classes and properties, which are used by the packages generated by
"gensuitemodule" to populate the classes and properties in a given
suite.

For reasons of backward compatibility, and for cases where you need to
script an application for which you have not generated the stub
package this module also contains object specifiers for a number of
common OSA classes such as "Document", "Window", "Character", etc.

Note: This module has been removed in Python 3.x.

The "AEObjects" module defines the following classes to represent
Apple Event descriptor data:

class aetypes.Unknown(type, data)

   The representation of OSA descriptor data for which the "aepack"
   and "aetypes" modules have no support, i.e. anything that is not
   represented by the other classes here and that is not equivalent to
   a simple Python value.

class aetypes.Enum(enum)

   An enumeration value with the given 4-character string value.

class aetypes.InsertionLoc(of, pos)

   Position "pos" in object "of".

class aetypes.Boolean(bool)

   A boolean.

class aetypes.StyledText(style, text)

   Text with style information (font, face, etc) included.

class aetypes.AEText(script, style, text)

   Text with script system and style information included.

class aetypes.IntlText(script, language, text)

   Text with script system and language information included.

class aetypes.IntlWritingCode(script, language)

   Script system and language information.

class aetypes.QDPoint(v, h)

   A quickdraw point.

class aetypes.QDRectangle(v0, h0, v1, h1)

   A quickdraw rectangle.

class aetypes.RGBColor(r, g, b)

   A color.

class aetypes.Type(type)

   An OSA type value with the given 4-character name.

class aetypes.Keyword(name)

   An OSA keyword with the given 4-character name.

class aetypes.Range(start, stop)

   A range.

class aetypes.Ordinal(abso)

   Non-numeric absolute positions, such as ""firs"", first, or
   ""midd"", middle.

class aetypes.Logical(logc, term)

   The logical expression of applying operator "logc" to "term".

class aetypes.Comparison(obj1, relo, obj2)

   The comparison "relo" of "obj1" to "obj2".

The following classes are used as base classes by the generated stub
packages to represent AppleScript classes and properties in Python:

class aetypes.ComponentItem(which[, fr])

   Abstract baseclass for an OSA class. The subclass should set the
   class attribute "want" to the 4-character OSA class code. Instances
   of subclasses of this class are equivalent to AppleScript Object
   Specifiers. Upon instantiation you should pass a selector in
   "which", and optionally a parent object in "fr".

class aetypes.NProperty(fr)

   Abstract baseclass for an OSA property. The subclass should set the
   class attributes "want" and "which" to designate which property we
   are talking about. Instances of subclasses of this class are Object
   Specifiers.

class aetypes.ObjectSpecifier(want, form, seld[, fr])

   Base class of "ComponentItem" and "NProperty", a general OSA Object
   Specifier. See the Apple Open Scripting Architecture documentation
   for the parameters. Note that this class is not abstract.
