/** |
|
52 |
* Represents an abstraction layer over a concrete XML parsing technology. |
|
53 |
* <p> |
|
54 |
* This interface provides a pull like approach to parsing xml formatted documents for the libGPE |
|
55 |
* library, yet allowing to interchange implementations which can be based, for example, in XML SAX, |
|
56 |
* XML Pull, Binary XML, etc. |
|
57 |
* </p> |
|
58 |
* <p> |
|
59 |
* Note at this time this interface contract is made just of the methods from XmlPullParser that |
|
60 |
* where already used so far in the libGPE-GML and libGPE-KML modules. The intention is to first |
|
61 |
* introduce this abstraction layer and then evolve it as needed to support an intermediate level of |
|
62 |
* abstraction between actual xml parsing and {@link IGPEContentHandler}, while keeping the unit |
|
63 |
* tests passing all the time. So this is work in progress and expected to change dramatically, |
|
64 |
* though ensuring no functional breackages in any time. |
