Class DefaultHandler2

public DefaultHandler2()

Constructs a handler which ignores all parsing events.

public void attributeDecl(String eName,
                          String aName,
                          String type,
                          String mode,
                          String value)
            throws SAXException

Report an attribute type declaration.

Only the effective (first) declaration for an attribute will be reported. The type will be one of the strings "CDATA", "ID", "IDREF", "IDREFS", "NMTOKEN", "NMTOKENS", "ENTITY", "ENTITIES", a parenthesized token group with the separator "|" and all whitespace removed, or the word "NOTATION" followed by a space followed by a parenthesized token group with all whitespace removed.

The value will be the value as reported to applications, appropriately normalized and with entity and character references expanded.

Specified by:

attributeDecl in interface DeclHandler

Parameters:

eName - The name of the associated element.

aName - The name of the attribute.

type - A string representing the attribute type.

mode - A string representing the attribute defaulting mode ("#IMPLIED", "#REQUIRED", or "#FIXED") or null if none of these applies.

value - A string representing the attribute's default value, or null if there is none.

Throws:

SAXException - The application may raise an exception.

public void comment(ch[] ,
                    int start,
                    int length)
            throws SAXException

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 LexicalHandler

Parameters:

start - The starting position in the array.

length - The number of characters to use from the array.

Throws:

SAXException - The application may raise an exception.

public void elementDecl(String name,
                        String model)
            throws SAXException

Report an element type declaration.

The content model will consist of the string "EMPTY", the string "ANY", or a parenthesised group, optionally followed by an occurrence indicator. The model will be normalized so that all parameter entities are fully resolved and all whitespace is removed,and will include the enclosing parentheses. Other normalization (such as removing redundant parentheses or simplifying occurrence indicators) is at the discretion of the parser.

Specified by:

elementDecl in interface DeclHandler

Parameters:

name - The element type name.

model - The content model as a normalized string.

Throws:

SAXException - The application may raise an exception.

public void endCDATA()
            throws SAXException

Report the end of a CDATA section.

Specified by:

endCDATA in interface LexicalHandler

Throws:

SAXException - The application may raise an exception.

See Also:

LexicalHandler.startCDATA()

public void endDTD()
            throws SAXException

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 LexicalHandler

Throws:

SAXException - The application may raise an exception.

See Also:

LexicalHandler.startDTD(String,String,String)

public void endEntity(String name)
            throws SAXException

Report the end of an entity.

Specified by:

endEntity in interface LexicalHandler

Parameters:

name - The name of the entity that is ending.

Throws:

SAXException - The application may raise an exception.

LexicalHandler.startEntity(String)

public void externalEntityDecl(String name,
                               String publicId,
                               String systemId)
            throws SAXException

Report a parsed external entity declaration.

Only the effective (first) declaration for each entity will be reported.

If the system identifier is a URL, the parser must resolve it fully before passing it to the application.

Specified by:

externalEntityDecl in interface DeclHandler

Parameters:

name - The name of the entity. If it is a parameter entity, the name will begin with '%'.

publicId - The entity's public identifier, or null if none was given.

systemId - The entity's system identifier.

Throws:

SAXException - The application may raise an exception.

public InputSource getExternalSubset(String name,
                                     String baseURI)
            throws SAXException,
                   IOException

Tells the parser that if no external subset has been declared in the document text, none should be used.

Specified by:

getExternalSubset in interface EntityResolver2

public void internalEntityDecl(String name,
                               String value)
            throws SAXException

Report an internal entity declaration.

Only the effective (first) declaration for each entity will be reported. All parameter entities in the value will be expanded, but general entities will not.

Specified by:

internalEntityDecl in interface DeclHandler

Parameters:

name - The name of the entity. If it is a parameter entity, the name will begin with '%'.

value - The replacement text of the entity.

Throws:

SAXException - The application may raise an exception.

public InputSource resolveEntity(String publicId,
                                 String systemId)
            throws SAXException,
                   IOException

Invokes EntityResolver2.resolveEntity() with null entity name and base URI. You only need to override that method to use this class.

Specified by:

resolveEntity in interface EntityResolver

Overrides:

resolveEntity in interface DefaultHandler

public InputSource resolveEntity(String name,
                                 String publicId,
                                 String baseURI,
                                 String systemId)
            throws SAXException,
                   IOException

Tells the parser to resolve the systemId against the baseURI and read the entity text from that resulting absolute URI. Note that because the older DefaultHandler.resolveEntity(), method is overridden to call this one, this method may sometimes be invoked with null name and baseURI, and with the systemId already absolutized.

Specified by:

resolveEntity in interface EntityResolver2

public void startCDATA()
            throws SAXException

Report the start of a CDATA section.

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

Specified by:

startCDATA in interface LexicalHandler

Throws:

SAXException - The application may raise an exception.

See Also:

LexicalHandler.endCDATA()

public void startDTD(String name,
                     String publicId,
                     String systemId)
            throws SAXException

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 events. Declarations are assumed to belong to the internal DTD subset unless they appear between startEntity and endEntity 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 event.

Specified by:

startDTD in interface LexicalHandler

Parameters:

name - The document type name.

publicId - The declared public identifier for the external DTD subset, or null if none was declared.

systemId - The declared system identifier for the external DTD subset, or null if none was declared. (Note that this is not resolved against the document base URI.)

Throws:

SAXException - The application may raise an exception.

See Also:

LexicalHandler.endDTD(), LexicalHandler.startEntity(String)

public void startEntity(String name)
            throws SAXException

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 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 LexicalHandler

Parameters:

name - The name of the entity. If it is a parameter entity, the name will begin with '%', and if it is the external DTD subset, it will be "[dtd]".

Throws:

SAXException - The application may raise an exception.
