## [Java] Class GroovyTypeCheckingExtensionSupport

- org.codehaus.groovy.transform.stc.GroovyTypeCheckingExtensionSupport

-     public class GroovyTypeCheckingExtensionSupport
      extends AbstractTypeCheckingExtension

  Base class for type checking extensions written in Groovy. Compared to its superclass, TypeCheckingExtension, this class adds a number of utility methods aimed at leveraging the syntax of the Groovy language to improve expressivity and conciseness.

  Since:
    2.1.0
