C# Класс Softing.OPCToolbox.Server.Creator

Helper class used as factory for various object instances of the OPC server components. This class is used by the Toolkit internal mechanisms to instantiate user specific objects. To enable this, the user must extend the Creator class and override the create methods.

Метод	Описание
CreateAeAddressSpaceElement ( ) : Softing.OPCToolbox.Server.AeAddressSpaceElement	Creates the AeAddressSpaceElement instance. This method should be overriden when a custom root is wanted.
CreateAeAddressSpaceRoot ( ) : Softing.OPCToolbox.Server.AeAddressSpaceRoot	Creates the AeAddressSpaceRoot instance
CreateDaAddressSpaceElement ( ) : Softing.OPCToolbox.Server.DaAddressSpaceElement	Creates the DaAddressSpaceElement instance. This method should be overriden when a custom root is wanted.
CreateDaAddressSpaceRoot ( ) : Softing.OPCToolbox.Server.DaAddressSpaceRoot	Creates the DaAddressSpaceRoot instance. This method should be overriden when a custom root is wanted.
CreateInternalAeAddressSpaceElement ( string aName, uint anUserData, uint anObjectHandle, uint aParentHandle ) : Softing.OPCToolbox.Server.AeAddressSpaceElement	Creates a new instance of AddressSpaceElement for string based address space only
CreateInternalDaAddressSpaceElement ( string anItemId, string aName, uint anUserData, uint anObjectHandle, uint aParentHandle ) : Softing.OPCToolbox.Server.DaAddressSpaceElement	Creates a new instance of DaAddressSpaceElement for string based address space only
CreateInternalDaAddressSpaceElementEx ( string anItemId, string aName, uint anUserData, uint anObjectHandle, uint aParentHandle, EnumAddressSpaceElementData elementDataFilter, EnumAccessRights accessRights, EnumIoMode ioMode, bool hasChildren, bool isBrowsable, Type dataType ) : Softing.OPCToolbox.Server.DaAddressSpaceElement	Creates a new instance of DaAddressSpaceElement for string based address space only (extended version). Must return a valid DaAddressSpaceElement object in order to have the Toolkit CORE use this extended method. If CreateInternalDaAddressSpaceElementEx method is correctly implemented, CreateInternalDaAddressSpaceElement will be ignored (will never be called unless CreateInternalDaAddressSpaceElementEx fails.
CreateRequest ( EnumTransactionType aTransactionType, uint aSessionHandle, Softing.OPCToolbox.Server.DaAddressSpaceElement anElement, int aPropertyId, uint aRequestHandle ) : DaRequest	Toolkit internal creator of a DaRequest. By overloading this method, the user can determine creation of custom Request objects.
CreateSession ( EnumSessionType aType, uint aHandle ) : Softing.OPCToolbox.Server.DaSession	Toolkit internal creator of a DaSession. By overloading this method, the user can determine creation of custom Session objects. The number of connected clients can be limited. This can be achieved by returning null instead of a new instance of the DaSession class if the number of clients exceeds a desired number.
CreateTransaction ( EnumTransactionType aTransactionType, Array aRequests, uint aSessionKey ) : Softing.OPCToolbox.Server.DaTransaction	Toolkit internal creator of a DaTransaction. By overloading this method, the user can determine creation of custom Transaction objects. All parameters should be forwarded directly to the custom Transaction class.
CreateWebTemplate ( ) : WebTemplate	Toolkit internal creator of a WebTemplate. By overloading this method, the user can determine creation of a custom WebTemplate handler instance. If web sever is used, this method shuld be overloaded
