Interface SqlXmlHandler

All Known Subinterfaces:
SqlXmlObjectMappingHandler
All Known Implementing Classes:
Jdbc4SqlXmlHandler

public interface SqlXmlHandler

Abstraction for handling XML fields in specific databases. Its main purpose is to isolate database-specific handling of XML stored in the database.

JDBC 4.0 introduces the new data type java.sql.SQLXML but most databases and their drivers currently rely on database-specific data types and features.

Provides accessor methods for XML fields and acts as factory for SqlXmlValue instances.

Since:
2.5.5
