Class GroovyResultSetProxy
java.lang.Object
groovy.sql.GroovyResultSetProxy
- All Implemented Interfaces:
InvocationHandler
GroovyResultSetProxy is used to create a proxy for GroovyResultSet.
Due to the version incompatibility between java 6 and older versions
methods with additional logic were moved into an extension class. When
getting properties or calling methods, the runtime will try to first
execute these on the extension and then on the ResultSet itself.
This way it is possible to replace and add methods. To overload methods
from ResultSet all methods have to be implemented on the extension
class.
