The following epics-related classes are not part of Epics namespace:

Class EpicsPvHeader

Public attributes:

   short int iPvId              //  process variable ID
   short int iDbrType           //  Epics Data Type
   short int iNumElements       //  Size of PV Array

Public Member Functions:

   EpicsPvHeader( short int iPvId1, short int iDbrType1, short int iNumElements1 ) :
                  iPvId(iPvId1),                         //  process variable ID
                  iDbrType(iDbrType1),                   //  Epics Data Type
                  iNumElements(iNumElements1)  {}        //  Size of PV Array

    int printPv() const;

Public Member Functions:

    static void* operator new(size_t size, char* p)     { return p; }
    // Disable ordinary (non-placement) new: only placement new and memory mapped objects are allowed
    // Disable placement delete: Not allow to delete memory mapped objects

Class EpicsPvCtrlHeader

Public attributes:

char        sPvName[_iMaxPvNameLength];

Public Member Functions:

    // Constructor
    EpicsPvCtrlHeader( short int iPvId1,
                       short int iDbrType1,
                       short int iNumElements1,
                       const char sPvName1[] )
                    :  EpicsPvHeader( iPvId1, iDbrType1, iNumElements1)

Class EpicsPvCtrl

Inherits from EpicsPvCtrlHeader and EpicsPvBase

Public Attributes:

  int printPv() const;
  enum { iDbrCtrlType = EpicsDbrTools::DbrTypeTraits<iDbrType1>::iDbrCtrlType };

Public Member Functions

              EpicsPvBase( *(EpicsPvBase*) pEpicsDataValue1 )

Class EpicsPvTime

Inherits from EpicsPvHeader and EpicsPvBase

Public Attributes:

    enum { iDbrTimeType = EpicsDbrTools::DbrTypeTraits<iDbrType1>::iDbrTimeType };
    typedef typename EpicsDbrTools::DbrTypeTraits<iDbrType1>::TDbrOrg TDbrOrg;

Public Member Functions:

     EpicsPvTime( short int iPvId1,
                  int iNumElements1,
                  void* pEpicsDataValue1,
                  int* piSize = NULL )
      :  EpicsPvHeader( iPvId1, iDbrTimeType, iNumElements1 ),

    int printPv() const;

Pds::Epics Namespace Reference.

EPICS (Experimental Physics and Industrial Control System) is used for hardware control and readout of hardware status, values etc. These are called process variables (PV). Pdsdata contains a package that holds the epics classes needed to read the process variables from the xtc file. This is not even a complete documentation of these classes, as it would be unneccesarily detailed. Here we aim just to include the main ingredients and what the user need to know to extract the data.

The following classes, typedefs and variables are part of Epics namespace:

struct  	dbr_time_long
struct  	dbr_time_double

struct  	dbr_ctrl_short
