Method Detail

next

public int next()
         throws java.io.IOException,
                org.apache.xerces.xni.XNIException

Drives the parser to the next state/event on the input. Parser is guaranteed to stop at the next state/event. Internally XML document is divided into several states. Each state represents a sections of XML document. When this functions returns normally, it has read the section of XML document and returns the state corresponding to section of document which has been read. For optimizations, a particular driver can read ahead of the section of document (state returned) just read and can maintain a different internal state.

Specified by:

next in interface XMLDocumentFragmentScannerImpl.Driver

Returns:

state representing the section of document just read.

Throws:

java.io.IOException - Thrown on i/o error.

org.apache.xerces.xni.XNIException - Thrown on parse error.
