## [Java] Class AbstractTypeCheckingExtension

- org.codehaus.groovy.transform.stc.AbstractTypeCheckingExtension

- Custom type checking extensions may extend this method in order to benefit from a lot of support methods.

  The methods found in this class are made directly available in type checking scripts through the GroovyTypeCheckingExtensionSupport class.

    - #### public MethodNode makeDynamic(MethodCall call)

      Used to instruct the type checker that the call is a dynamic method call. Calling this method automatically sets the handled flag to true. The expected return type of the dynamic method call is Object.

      Parameters:
        `call` - the method call which is a dynamic method call
      Returns:
        a virtual method node with the same name as the expected call

    - #### public MethodNode makeDynamic(MethodCall call, ClassNode returnType)

      Used to instruct the type checker that the call is a dynamic method call. Calling this method automatically sets the handled flag to true.

      Parameters:
        `call` - the method call which is a dynamic method call
        `returnType` - the expected return type of the dynamic call
      Returns:
        a virtual method node with the same name as the expected call

    - #### public void makeDynamic(PropertyExpression pexp)

      Instructs the type checker that a property access is dynamic, returning an instance of an Object. Calling this method automatically sets the handled flag to true.

      Parameters:
        `pexp` - the property or attribute expression

    - #### public void makeDynamic(PropertyExpression pexp, ClassNode returnType)

      Instructs the type checker that a property access is dynamic. Calling this method automatically sets the handled flag to true.

      Parameters:
        `pexp` - the property or attribute expression
        `returnType` - the type of the property

    - #### public void makeDynamic(VariableExpression vexp)

      Instructs the type checker that an unresolved variable is a dynamic variable of type Object. Calling this method automatically sets the handled flag to true.

      Parameters:
        `vexp` - the dynamic variable

    - #### public void makeDynamic(VariableExpression vexp, ClassNode returnType)

      Instructs the type checker that an unresolved variable is a dynamic variable.

      Parameters:
        `returnType` - the type of the dynamic variable Calling this method automatically sets the handled flag to true.
        `vexp` - the dynamic variable
