Package org.datanucleus.store.rdbms.sql.method Description

Support for invocation of Java methods, typically using SQL functions. Registered using the plugin-point org.datanucleus.store.rdbms.sql_method allowing users to register handling for particular methods to override/extend the default behaviour. All RDBMS have their own set of SQL functions and this is typically used to provide for all different possible SQL functions and tie them to a datastore.
