Class XSDHandler

java.lang.Object

org.apache.xerces.impl.xs.traversers.XSDHandler

public class XSDHandler
extends Object

The purpose of this class is to co-ordinate the construction of a grammar object corresponding to a schema. To do this, it must be prepared to parse several schema documents (for instance if the schema document originally referred to contains or information items). If any of the schemas imports a schema, other grammars may be constructed as a side-effect.

Method Detail

parseSchema

public SchemaGrammar parseSchema(XMLInputSource is,
                        XSDDescription desc,
                        Hashtable locationPairs)
                          throws IOException

This method initiates the parse of a schema. It will likely be called from the Validator and it will make the resulting grammar available; it returns a reference to this object just in case. A reset(XMLComponentManager) must be called before this methods is called.

Parameters:

is -

desc -

locationPairs -

Returns:

the SchemaGrammar

Throws:

IOException

findGrammar

protected SchemaGrammar findGrammar(XSDDescription desc,
                        boolean ignoreConflict)

First try to find a grammar in the bucket, if failed, consult the grammar pool. If a grammar is found in the pool, then add it (and all imported ones) into the bucket.

constructTrees

protected org.apache.xerces.impl.xs.traversers.XSDocumentInfo constructTrees(Element schemaRoot,
                                                                 String locationHint,
                                                                 XSDDescription desc,
