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
