Description
This method returns a set of flags indicating the status of the OParameter.

int GetStatus(void) const

Remarks
You can use this method to query a parameter's state. It reports the state by means of a single integer which contain flags. These flags are ORed together, and can have the following values:

· OPARAMETER_STATUS_IN // on if the parameter is an in variable

· OPARAMETER_STATUS_OUT // on if the parameter is an out variable

· OPARAMETER_STATUS_AUTOENABLED // on if the parameter is auto-enabled

· OPARAMETER_STATUS_ENABLED // on if the parameter is enabled

Auto-enabling is set with the AutoEnable method. The in and out status of a parameter is set when the parameter is created with OParameterSet::Add. A parameter is enabled if it is ready to be used as a parameter, which means that it is auto-enabled, has a name and a valid value. If you have created the parameter with OParameterSet::Add then it will be enable if it is auto-enabled.
