  +--weblogic.apache.xerces.parsers.XMLGrammarPreparser

public class XMLGrammarPreparser

extends java.lang.Object

This class provides an easy way for a user to preparse grammars of various types. By default, it knows how to preparse external DTD's and schemas; it provides an easy way for user applications to register classes that know how to parse additional grammar types. By default, it does no grammar caching; but it provides ways for user applications to do so.

Constructor Detail

XMLGrammarPreparser

public XMLGrammarPreparser()

Default constructor.

XMLGrammarPreparser

public XMLGrammarPreparser(SymbolTable symbolTable)

Constructs a preparser using the specified symbol table.

Parameters:

symbolTable - The symbol table to use.

Method Detail

registerPreparser

public boolean registerPreparser(java.lang.String grammarType,
                                 XMLGrammarLoader loader)

preparseGrammar

public Grammar preparseGrammar(java.lang.String type,
                               XMLInputSource is)
                        throws XNIException,
                               java.io.IOException

Parse a grammar from a location identified by an XMLInputSource. This method also adds this grammar to the XMLGrammarPool

Parameters:

type - The type of the grammar to be constructed

source - The XMLInputSource containing this grammar's information If a URI is included in the systemId field, the parser will not expand this URI or make it available to the EntityResolver

Returns:

The newly created Grammar.

Throws:

XNIException - thrown on an error in grammar construction

java.io.IOException - thrown if an error is encountered in reading the file

setLocale
