How to create a new persistent memory segment in MemoryX

• Create Ice interface for new segment in MemoryX/interface/memorytypes/MemorySegments.ice which inherits from memoryx::PersistentEntitySegmentBase

  ["cpp:virtual"]
  class PersistentDataSegmentBase extends PersistentEntitySegmentBase
  {
      // add some special methods here
  };

• Create C++ header file

  #ifndef ARMARX_MEMORYX_NEW_DATA_SEGMENT_H
  #define ARMARX_MEMORYX_NEW_DATA_SEGMENT_H
   
  #include "../entity/profiler/ProfilerTransition.h"
   
  #include <MemoryX/core/memory/PersistentEntitySegment.h>
  #include <MemoryX/interface/memorytypes/MemorySegments.h>
   
  #include <ArmarXCore/core/system/ImportExportComponent.h>
   
  namespace memoryx
  {
      class ARMARXCOMPONENT_IMPORT_EXPORT PersistentDataSegment :
          virtual public PersistentEntitySegment,
          virtual public PersistentDataSegmentBase
      {
          public:
              PersistentDataSegment(CollectionInterfacePrx entityCollection, Ice::CommunicatorPtr communicator, bool useMongoIds = true);
   
          // implementation of Ice interface methods
          ["cpp:const"]
          hasDataEntity(string name);
      };
   
      using PersistentProfilerDataSegmentPtr = IceInternal::Handle<PersistentProfilerDataSegment>;
  }
   
  #endif

• Create C++ implementation file

  #include "PersistentDataSegment.h"
   
  using namespace memoryx;
   
  PersistentDataSegment::PersistentDataSegment(CollectionInterfacePrx entityCollection, Ice::CommunicatorPtr communicator, bool useMongoIds) :
      PersistentEntitySegment(entityCollection, communicator, useMongoIds),
      PersistentDataSegmentBase()
  {
  }
   
  // implementation of further methods

• Add header and implementation files to the appropriate CMake target.

• Add/register new segment in memoryx::PriorKnowledge or memoryx::LongtermMemory and add accessor functions to the recpective memory interface.
