The jboStructureParameterDescriptor Class 

The jboStructureParameterDescriptor class describes structure parameter objects. This class is derived from com.sap.bapi.jboParameterDescriptor . Application programs can use this class to retrieve information about a structure parameter and the fields defined in the com.sap.rfc.ComplexInfo class. In addition, programs can use this class to set values to the specified structure parameter using the Core Reflection API.

This class offers these two methods: getComplexInfo and getReferenceStructureType. For more information on these methods, please see the Java BAPI HTML Reference.
