## [Java] Class DefaultTypeCheckingExtension

- org.codehaus.groovy.transform.stc.DefaultTypeCheckingExtension

- The default type checking handler is used by the standard type checker and doesn't handle any of the type checking errors by default. This just means that whenever a type checking error is detected, there's no additional information available to the type checker that could help it. The default handler is also capable of handling a collection of delegate handlers. If a list of delegates is set, then the type checker will try all the delegates until one is capable of handling an error.

  Since:
    2.1.0
