|
| CreateObjRef | Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.) |
| EndMemoryOptimizedReadMultiSample |
Handles the end of an asynchronous read initiated with
BeginMemoryOptimizedReadMultiSample(Int32, AsyncCallback, Object, Double)
and retrieves the read samples.
|
| EndMemoryOptimizedReadWaveform |
Handles the end of an asynchronous read initiated with
BeginMemoryOptimizedReadWaveform(Int32, AsyncCallback, Object, AnalogWaveformDouble)
and retrieves the read samples.
|
| EndReadMultiSample | Handles the end of an asynchronous read initiated with BeginReadMultiSample(Int32, AsyncCallback, Object) and retrieves the read samples. |
| EndReadSingleSample | Handles the end of an asynchronous read initiated with BeginReadSingleSample(AsyncCallback, Object) and retrieves the read samples. |
| EndReadWaveform | Handles the end of an asynchronous read initiated with BeginReadWaveform(Int32, AsyncCallback, Object) and retrieves the read samples. |
| Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
 | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetLifetimeService | Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| InitializeLifetimeService | Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| MemberwiseClone(Boolean) | Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.) |
