## [Java] Class GroovyResultSetProxy

- groovy.sql.GroovyResultSetProxy

- All Implemented Interfaces and Traits:
    InvocationHandler

      public final class GroovyResultSetProxy

  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.

    - #### public GroovyResultSetProxy(GroovyResultSetExtension ext)

      Creates a new proxy instance with a custom extension.

      Parameters:
        `ext` - the extension

        GroovyResultSetExtension

  - ### Method Detail

    - #### public GroovyResultSet getImpl()

      Gets a proxy instance that can be used as GroovyResultSet.

      Returns:
        the proxy

    - #### public Object invoke(Object proxy, Method method, Object[] args)

      Invokes a method for the GroovyResultSet. This will try to invoke the given method first on the extension and then on the result set given as proxy parameter.

      Parameters:
        `proxy` - the result set
        `method` - the method name of this method will be used to make a call on the extension. If this fails the call will be done on the proxy instead
        `args` - for the call
