Class SchemaParser

java.lang.Object
  oracle.adf.model.adapter.dataformat.xml.SchemaParser

public class SchemaParser
extends java.lang.Object

Attempts to parses the given XSD document even in cases where the <import> elements do not specify schemaLocation attribute.

The parser works in a recursive fashion and parses the imported schemas and namespaces in all the referred schemas. It builds a list of all the schemas referred directly or indirectly and calls XSDBuilder.build(XMLDocument[], URL) to build the schema.

Input for parsing can be set using any of the addSchema methods. Alternatively, if only one schema document is to be parser, one of the parse methods may be used. The parse methods return XMLSchema object representing the parsed schema document.
