CMTPTypeInterdependentPropDesc Class Reference

class CMTPTypeInterdependentPropDesc : public CMTPTypeCompoundBase

Defines the MTP InterdependentPropDesc dataset. The InterdependentPropDesc implements an array of MTP ObjectPropDesc arrays, each describing a permissable collection of ranges. Each array of MTP ObjectPropDesc datasets gives one possible definition for the interdependent properties that are contained in that array; properties not found in that array are constrained only by the usual ObjectPropDesc datasets. This dataset is used in the GetInterdependentPropDesc request.
