      Object getTarget()
      Returns the target instance.

    • getMethod

      Method getMethod()
      Returns the method of the bean class for which the interceptor was invoked. For AroundInvoke methods, this is the business method on the bean class. For lifecycle callback methods, returns null.

    • getParameters

      Object[] getParameters()
      Returns the parameters that will be used to invoke the business method. If setParameters has been called, getParameters() returns the values to which the parameters have been set.
      Throws:
      IllegalStateException - if invoked within a lifecycle callback method.

    • setParameters

      void setParameters(Object[] params)
      Sets the parameters that will be used to invoke the business method.
      Throws:
      IllegalStateException - if invoked within a lifecycle callback method.
      IllegalArgumentException - if the parameter types do not match the types for the business method, or the number of parameters supplied does not equal the number of parameters for the business method.

    • getContextData

      Map<String,Object> getContextData()
      Returns the context data associated with this invocation or lifecycle callback. If there is no context data, an empty Mapinvalid input: '<'String,Object> object will be returned.

    • proceed

      Object proceed() throws Exception
      Proceed to the next entry in the interceptor chain. The proceed method returns the result of the next method invoked. If the method returns void, proceed returns null.
      Throws:
