org.apache.axis.encoding
Class DeserializationContext.NullLexicalHandler  

java.lang.Object
  org.apache.axis.encoding.DeserializationContext.NullLexicalHandler

All Implemented Interfaces:

org.xml.sax.ext.LexicalHandler

Enclosing class:

DeserializationContext

---

private static class DeserializationContext.NullLexicalHandler

extends java.lang.Object

implements org.xml.sax.ext.LexicalHandler

It is illegal to set the lexical-handler property to null. To facilitate discarding the heavily loaded instance of DeserializationContextImpl from the SAXParser instance that is kept in the Stack maintained by XMLUtils we use this class.

Method Detail

startDTD

public void startDTD(java.lang.String arg0,
                     java.lang.String arg1,
                     java.lang.String arg2)
              throws org.xml.sax.SAXException

Description copied from interface: org.xml.sax.ext.LexicalHandler

Report the start of DTD declarations, if any.

This method is intended to report the beginning of the DOCTYPE declaration; if the document has no DOCTYPE declaration, this method will not be invoked.

All declarations reported through DTDHandler or DeclHandler events must appear between the startDTD and endDTD 55 events. Declarations are assumed to belong to the internal DTD subset unless they appear between startEntity 55 and endEntity 55 events. Comments and processing instructions from the DTD should also be reported between the startDTD and endDTD events, in their original order of (logical) occurrence; they are not required to appear in their correct locations relative to DTDHandler or DeclHandler events, however.

Note that the start/endDTD events will appear within the start/endDocument events from ContentHandler and before the first startElement 55 event.

Specified by:

startDTD in interface org.xml.sax.ext.LexicalHandler

---

endDTD

public void endDTD()
            throws org.xml.sax.SAXException

Description copied from interface: org.xml.sax.ext.LexicalHandler

Report the end of DTD declarations.

This method is intended to report the end of the DOCTYPE declaration; if the document has no DOCTYPE declaration, this method will not be invoked.

Specified by:

endDTD in interface org.xml.sax.ext.LexicalHandler

---

startEntity

public void startEntity(java.lang.String arg0)
                 throws org.xml.sax.SAXException

Description copied from interface: org.xml.sax.ext.LexicalHandler

Report the beginning of some internal and external XML entities.

The reporting of parameter entities (including the external DTD subset) is optional, and SAX2 drivers that report LexicalHandler events may not implement it; you can use the http://xml.org/sax/features/lexical-handler/parameter-entities feature to query or control the reporting of parameter entities.

General entities are reported with their regular names, parameter entities have '%' prepended to their names, and the external DTD subset has the pseudo-entity name "[dtd]".

When a SAX2 driver is providing these events, all other events must be properly nested within start/end entity events. There is no additional requirement that events from DeclHandler or DTDHandler be properly ordered.

Note that skipped entities will be reported through the skippedEntity 55 event, which is part of the ContentHandler interface.

Because of the streaming event model that SAX uses, some entity boundaries cannot be reported under any circumstances:

• general entities within attribute values
• parameter entities within declarations

These will be silently expanded, with no indication of where the original entity boundaries were.

Note also that the boundaries of character references (which are not really entities anyway) are not reported.

All start/endEntity events must be properly nested.

Specified by:

startEntity in interface org.xml.sax.ext.LexicalHandler

---

endEntity

public void endEntity(java.lang.String arg0)
               throws org.xml.sax.SAXException

Description copied from interface: org.xml.sax.ext.LexicalHandler

Report the end of an entity.

Specified by:

endEntity in interface org.xml.sax.ext.LexicalHandler

---

startCDATA

public void startCDATA()
                throws org.xml.sax.SAXException

Description copied from interface: org.xml.sax.ext.LexicalHandler

Report the start of a CDATA section.

The contents of the CDATA section will be reported through the regular characters 55 event; this event is intended only to report the boundary.

Specified by:

startCDATA in interface org.xml.sax.ext.LexicalHandler

---

endCDATA

public void endCDATA()
              throws org.xml.sax.SAXException

Description copied from interface: org.xml.sax.ext.LexicalHandler

Report the end of a CDATA section.

Specified by:

endCDATA in interface org.xml.sax.ext.LexicalHandler

---

comment

public void comment(char[] arg0,
                    int arg1,
                    int arg2)
             throws org.xml.sax.SAXException

Description copied from interface: org.xml.sax.ext.LexicalHandler

Report an XML comment anywhere in the document.

This callback will be used for comments inside or outside the document element, including comments in the external DTD subset (if read). Comments in the DTD must be properly nested inside start/endDTD and start/endEntity events (if used).

Specified by:

comment in interface org.xml.sax.ext.LexicalHandler
