Package org.eclipse.persistence.sdo.helper

Interface Summary

Interface	Description
CodeWriter	Purpose:This interface can be implemented and used in conjunction with SDOClassGenerator to write the generated source as desired.
SchemaLocationResolver	Purpose: Interface that can be optionally implemented to resolve the value for the schemaLocation attribute of generated imports and includes when generating schemas.
SchemaResolver	Purpose: Interface that can be optionally implemented to resolve imported and included schemas.
SDOClassGeneratorListener	Purpose: Optionally user can implement this interface to provide their own extra content to the generated source files.
SDODataFactory	Purpose: The implementation of commonj.sdo.helper.DataFactory
SDOTypeHelper	Purpose: Helper to provide access to declared SDO Types.
SDOXMLHelper	Purpose: Helper to transform XML documents into DataObects and DataObjects into XML documents.
SDOXSDHelper	Purpose: Provides access to additional information when the Type or Property is defined by an XML Schema (XSD).

Class Summary

Class	Description
ApplicationResolver	This class provides a means for the user to return application-specific information, such as the application name, which will be used when the logic in SDOHelperContext fails.
AttributeMimeTypePolicy
ClassBuffer	Purpose: This class maintains information about a generated class and its corresponding interface Responsibilities: Hold the StringBuffer contents of the class and interface When the close() method is called the attribute and method buffers are appended to the classbuffer and both the interface buffer and class buffer have the closing brace appended
DataObjectInputStream
DefaultSchemaLocationResolver	Purpose: Default implementation of the org.eclipse.persistence.sdo.helper.SchemaLocationResolver interface By default set a Map keyed on QName of types and value is the schemaLocation
DefaultSchemaResolver	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
DynamicClassWriter
FileCodeWriter	Purpose:Used in conjunction with SDOClassGenerator.
InstanceClassConverter	Purpose: A converter used in conjunction with sdoJava:instanceClass The customClass on the converter must be set and that class must have a Constructor that takes a String argument and a toString method.
ListWrapper	INTERNAL: Purpose: This class wraps the ArrayList of currentElements that implement the List interface.
MapKeyLookupResult	Class for wrapping cache key lookup results.
SchemaResolverWrapper	Purpose: Allow the contained schema resolver to resolve a schema based on a given namespace and schema location, and return either the resolved schema source or null, depending on whether the schema had been processed previously.
SDOClassGenerator	Purpose<>/b: Generate Java interfaces and implementation classes from a list of SDO Type objects.
SDOClassLoader	Purpose: A custom classloader used to dynamically create classes as needed.
SDOCopyHelper	Purpose: A helper class for making deep or shallow copies of DataObjects.
SDOCSUnmarshalListener	Purpose: Implementation of XMLUnmarshalListener used when unmarshalling XML to XMLDocuments Responsibilities: When creating a DataObject we need to call setType and setHelperContext with the appropriate values
SDODataHelper	Purpose: A helper class for performing data conversions.
SDOEqualityHelper	Purpose: A helper class for checking deep or shallow equality of DataObjects.
SDOFragmentMappingAttributeAccessor	Purpose: A wrapper class for handling cases when the domain object attributes are to be accessed thru the accessor methods that are called "get" and "set".
SDOHelperContext	Purpose: This class represents a local HelperContext.
SDOHelperContext.MyNotificationFilter	INTERNAL: This class will be handed in as a parameter when adding a JBoss notification listener.
SDOMarshalListener	Purpose: Implementation of XMLMarshalListener used when marshalling DataObjects to XML Responsibilities: Need to do extra work to marshal org.eclipse.persistence.sdo.SDOChangeSummary objects
SDOMethodAttributeAccessor	Purpose: A wrapper class for handling cases when the domain object attributes are to be accessed thru the accessor methods that are called "get" and "set".
SDOSchemaGenerator	Purpose SDOSchemaGenerator generates an XSD (returned as a String) from a list of SDO Type objects.
SDOTypesGenerator	Purpose: Called from XSDHelper define methods to generate SDO Types from a Schema
SDOUnmappedContentHandler	Purpose: Called during XMLHelper load methods when there is unknown content in an XML document.
SDOUnmarshalListener	Purpose: Implementation of XMLUnmarshalListener used when unmarshalling XML to XMLDocuments Responsibilities: When creating a DataObject we need to call setType and setHelperContext with the appropriate values When we are finished Unmarshalling the root object we need to set up the ChangeSummary objects.
XPathEngine	Purpose: Perform operations based on SDO XPath against DataObjects.
