Class DefaultSchemaResolver

java.lang.Object
org.eclipse.persistence.sdo.helper.DefaultSchemaResolver

All Implemented Interfaces:

SchemaResolver, org.xml.sax.EntityResolver

public class DefaultSchemaResolver

extends java.lang.Object

implements SchemaResolver

Purpose: Default implementation of the org.eclipse.persistence.sdo.helper.SchemaResolver interface

Responsibilities:

• Given the source schema and namespace and schemaLocation values from an import or include return the referenced Schema
• If a baseSchemaLocation is set it will be prepended to all schemaLocations passed into the resovleSchema methods
• This implementation will try to open an Inputstream to a URL created from the schemaLocation and return a StreamSource based on that inputstream

sourceXSD - The Source object of the source schema

namespace - The namespace portion of the import/include

schemaLocation - The schemaLocation portion of the import/include
