TIBCO Adapter SDK C++ Reference
MInstance::setNullData
MInstance
Set the value of the named attribute explicitly to NULL.
Remarks
Calling this method:

  1. Clears the value of attributeName.

  2. Adds the attribute to the null value list.

  3. Uses the attributeName value for data marshalling.
Note
On the receiving side, the default value will NOT be set because the attribute is in the null list and does not create the MInstance object with the default value.
Parameters
Parameters Description
const MString& rsAttributeName Name of the attribute in this instance that you want to set to NULL.
Exceptions
MException if the specified attribute is not defined in the class description.
Declaration
virtual void setNullData(const MString& rsAttributeName) throw(MException);
