Extension Methods
 NameDescription
Public Extension MethodFilter the mappings available on the mapper by the given criteria.
Public Extension MethodOverloaded. Executes the "Get" operation on members of given target object.The "Get" operation obtains value of an OPC property and stores it into the mapping source. Only mappings of type OpcLabs.EasyOpc.DataAccess.LiveMapping.DAPropertyMapping are affected; other mappings are ignored.
Public Extension MethodOverloaded. Executes the "Read" operation on members of given target object.The "Read" operation reads a value of an OPC item and stores it into the mapping source. Only mappings of type OpcLabs.EasyOpc.DataAccess.LiveMapping.DAItemMapping that include OpcLabs.EasyOpc.DataAccess.LiveMapping.DAItemMappingOperations.Read in their OpcLabs.EasyOpc.DataAccess.LiveMapping.DAClientItemMapping.Operations are affected; other mappings are ignored.
Public Extension MethodOverloaded. Executes the "Subscribe" operation on members of given target object.The "Subscribe" operation subscribes to or unsubscribes from changes of an OPC item. Only mappings of type OpcLabs.EasyOpc.DataAccess.LiveMapping.DAItemMapping that include OpcLabs.EasyOpc.DataAccess.LiveMapping.DAItemMappingOperations.Subscribe in their OpcLabs.EasyOpc.DataAccess.LiveMapping.DAClientItemMapping.Operations are affected; other mappings are ignored.
Public Extension MethodOverloaded. Executes the "Write" operation on members of given target object.The "Write" operation writes a value from the mapping source into an OPC item. Only mappings of type OpcLabs.EasyOpc.DataAccess.LiveMapping.DAItemMapping that include OpcLabs.EasyOpc.DataAccess.LiveMapping.DAItemMappingOperations.Write in their OpcLabs.EasyOpc.DataAccess.LiveMapping.DAClientItemMapping.Operations are affected; other mappings are ignored.
