Should return true if the handler can read from the stream.
A typical implementation is to read the first part of the file, to see if the contents is right for this handler. Then it resets the file pointer to the beginning again.
In general a handler is written with a certain type of document in mind, since that is where the information will be stored. The document view framework, uses document templates to get to input handlers. The last 2 parameters can be checked if set. Use SetDocumentClassInfo() to set the right classinfo, in case of a derived document object, which still can be read with the this handler. Like:
a2dIOHandlerKeyIn* keyhin = new a2dIOHandlerKeyIn(); keyhin->SetDocumentClassInfo( &MyDocument::ms_classInfo );
- Parameters:
-
stream the open stream which its header can be tested obj to check and load the data into, needs to be casted to the right one internal. docClassInfo to check if the inout handler is indeed able to read document of m_docClassInfo.

| bool a2dIOHandlerSVGIn::Load | ( | a2dDocumentInputStream & | stream, | |
| wxObject * | obj | |||
| ) | [virtual] |
override to read the stream and store (part of) the contents in to a specific a2dDocument or othere object.
Understand that a a2dDocument itself is useless for storing data, so it needs to be casted internal.
- Parameters:
-
stream the open stream to load from obj to load the data into, needs to be casted to the right one internal.
