3. Packing and unpacking data
Codecs
The aem.Codecs
class provides methods for converting Python data to aem.ae.AEDesc
objects, and vice-versa.
Codecs
Constructor:
__init__(self)
Methods:
pack(self, data) -- convert Python data to an AEDesc; will
raise a TypeError if data's type/class is unsupported
data : anything
Result : AEDesc
unpack(self, desc) -- convert an AEDesc to Python data;
will return AEDesc if it's an unsupported type
desc : AEDesc
Result : anything
AE types
The Apple Event Manager defines several types for representing type/class names, enumerator names, etc. that have no direct equivalent in Python. Accordingly, AEM defines several classes to represent these types on the Python side. All share a common abstract base class, AETypeBase
:
AETypeBase -- Abstract base class
Constructor:
__init__(self, code)
code : bytes -- a four-character Apple event code
Properties:
code : bytes (read-only) -- Apple event code
The four concrete classes are:
AEType(AETypeBase) -- represents an AE object of typeType
AEEnum(AETypeBase) -- represents an AE object of typeEnumeration
AEProp(AETypeBase) -- represents an AE object of typeProperty
AEKey(AETypeBase) -- represents an AE object of typeKeyword
