OutputAdapterBase Class

Represents the base class for any outgoing data stream.

Definition

Namespace: Gemstone.Timeseries.Adapters
Assembly: Gemstone.Timeseries (in Gemstone.Timeseries.dll) Version: 1.0.128 -- Release Build+e2476c52e94864f123f37e60764c948e49eb89eb
Inheritance
Object    AdapterBase    OutputAdapterBase
Implements
IProvideStatus, ISupportLifecycle, IAdapter, IOutputAdapter, IDisposable

Remarks

This base class acts as a measurement queue so that output adapters can temporarily go offline without losing any measurements to be processed. Derived classes are expected to override ProcessMeasurements(IMeasurement) to handle queued measurements.

Constructors

OutputAdapterBase Constructs a new instance of the OutputAdapterBase.

(Inherited from AdapterBase)
StartTimeConstraint Gets the start time temporal processing constraint defined by call to SetTemporalConstraint(String, String, String).
(Inherited from AdapterBase)
Status Returns the detailed status of the data input source. Derived classes should extend status with implementation specific information.
(Overrides AdapterBaseStatus)
StopTime Gets the UTC time this AdapterBase was stopped.
(Inherited from AdapterBase)
StopTimeConstraint Gets the stop time temporal processing constraint defined by call to SetTemporalConstraint(String, String, String).

Methods

AttemptConnection Attempts to connect to data output stream.
AttemptDisconnection Attempts to disconnect from data output stream.
Dispose Releases all the resources used by the AdapterBase object.
(Inherited from AdapterBase)
Dispose(Boolean) Releases the unmanaged resources used by the OutputAdapterBase object and optionally releases the managed resources.
(Overrides AdapterBaseDispose(Boolean))
EqualsDetermines whether the specified object is equal to the current object.
(Inherited from Object)
ExecuteMetadataRefresh Executes the metadata refresh in a synchronous fashion.
Finalize Releases the unmanaged resources before the AdapterBase object is reclaimed by GC.
(Inherited from AdapterBase)
Flush Blocks the current thread, if the OutputAdapterBase is connected, until all items in OutputAdapterBase queue are processed, and then stops processing.
GetHashCode Serves as a hash function for the current AdapterBase.
(Inherited from AdapterBase)
GetShortStatus Gets a short one-line status of this AdapterBase.
(Inherited from AdapterBase)
GetTypeGets the Type of the current instance.
(Inherited from Object)
IncrementProcessedMeasurements Safely increments the total processed measurements.
(Inherited from AdapterBase)
Initialize Initializes OutputAdapterBase.
(Overrides AdapterBaseInitialize)
MemberwiseCloneCreates a shallow copy of the current Object.
(Inherited from Object)
OnConfigurationChanged Raises ConfigurationChanged event.
(Inherited from AdapterBase)
OnConnected Called when data output source connection is established.
OnDisconnected Called when data input source is disconnected.
OnInputMeasurementKeysUpdated Raises InputMeasurementKeysUpdated event.
(Inherited from AdapterBase)
OnOutputMeasurementsUpdated Raises OutputMeasurementsUpdated event.
(Inherited from AdapterBase)
OnProcessException Raises the ProcessException event.
(Inherited from AdapterBase)
OnStatusMessage Raises the StatusMessage event and sends this data to the Logger.
(Inherited from AdapterBase)
OnUnprocessedMeasurements Raises the UnprocessedMeasurements event.
ProcessMeasurements Serializes measurements to data output stream.
QueueMeasurementForProcessing Queues a single measurement for processing. Measurement is automatically filtered to the defined InputMeasurementKeys.
QueueMeasurementsForProcessing Queues a collection of measurements for processing. Measurements are automatically filtered to the defined InputMeasurementKeys.
RefreshMetadata Initiates request for metadata refresh for OutputAdapterBase, if implemented.
RemoveMeasurements This removes a range of measurements from the internal measurement queue.
SetInitializedState Manually sets the initialized state of the AdapterBase.
(Inherited from AdapterBase)
SetTemporalConstraint Defines a temporal processing constraint for the adapter.
(Inherited from AdapterBase)
Start Starts this OutputAdapterBase and initiates connection cycle to data output stream.
(Overrides AdapterBaseStart)
Stop Stops this OutputAdapterBase and disconnects from data output stream.
(Overrides AdapterBaseStop)
ToStringReturns a string that represents the current object.
(Inherited from Object)

Events

ConfigurationChanged Event is raised when adapter is aware of a configuration change.
(Inherited from AdapterBase)
