Detailed Description

Callback class for file read abstraction.

With this, it is possible to make the xml parser read in other things than just files. The Irrlicht engine is using this for example to read xml from compressed .zip files. To make the parser read in any other data, derive a class from this interface, implement the two methods to read your data and give a pointer to an instance of your implementation when calling createIrrXMLReader(), createIrrXMLReaderUTF16() or createIrrXMLReaderUTF32()
