|
31 Objects of this class are used to describe the objects to be transferred and |
|
32 those received via Obex. |
|
33 Consists of a number of attributes describing the object, along with |
|
34 methods to set them. CObexBaseObject is an abstract base class, which defines |
|
35 attribute setting and transferring functionality, but does not specify the |
|
36 storage mechanism for the data part (called the object body) of the object. |
|
37 This body part is defined in derived classes. |
|
38 |
|
39 Object description attributes are tracked for validity automatically, so |
|
40 that only valid attributes are sent to the remote machine. Also has the |
|
41 concept of "header masks". This selects which of the various attributes |
|
42 will actually be sent out/read in when the object is used in an operation |
|
43 with the remote machine. Objects default to transferring all valid |
|
44 attributes, use the header mask if restriction is required on the headers |
|
45 exchanged. |
|
46 |
|
47 See the various derived classes for description of object body |
|
48 representation. |
|
49 |
|
50 The common attributes are defined to be as close to the underlying OBEX |
|
51 headers as usefully possible, hence any OBEX header specified as a Unicode |
|
52 string (e.g. Name) translate to TDes (variant) EPOC descriptors, "byte |
|
53 sequences" (e.g. Type) are TDes8 (or ASCII invariant), and byte and 32 bit |
|
54 integers (e.g. Length) are TUint32s. |
|
55 |
|
56 This class is not designed for user derivation (ie. outside of this dll). |
