The Operator type exposes the following methods.
Methods
 Public Protected | Instance Static | Declared Inherited | XNA Framework Only .NET Compact Framework Only |
| Member | Description | |||
|---|---|---|---|---|
 | CreateObjRef(Type) | Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.) | ||
| Equals(Object) | (Inherited from Object.) | ||
| GetHashCode()()()() | Serves as a hash function for a particular type. (Inherited from Object.) | ||
| GetInputPortCount()()()() |
Returns the number of configured input ports for this operator.
| ||
| GetInputSchema(Int32) |
Provides access to the operator's input schemas.
| ||
| GetLifetimeService()()()() | Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.) | ||
| GetOutputPortCount()()()() |
Returns the number of configured output ports for this operator.
| ||
| GetOutputSchema(Int32) |
Provides access to the operator's output schemas.
| ||
| GetParameterAsString(String) |
Returns the given parameter as a string value. The Java portion of the operator must implment
String getStringParameter(String) and return an appropriate value.
The default will reutrn an empty string.
| ||
| GetType()()()() | Gets the Type of the current instance. (Inherited from Object.) | ||
| Init()()()() |
After the Operator has been created but before the
application start, this method will be called. Operators should
override this method to perform custom initialization.
| ||
| InitializeLifetimeService()()()() | (Overrides MarshalByRefObject..::..InitializeLifetimeService()()()().) | ||
| Log(Operator..::..Logger..::..LogLevel, String) |
Sends the given string to the StreamBase application's logging system.
| ||
| LogDebug(String) |
Sends the given string to the StreamBase application's logging system with a loglevel of DEBUG.
| ||
| LogError(String) |
Sends the given string to the StreamBase application's logging system with a loglevel of ERROR.
| ||
| LogInfo(String) |
Sends the given string to the StreamBase application's logging system with a loglevel of INFO.
| ||
| LogTrace(String) |
Sends the given string to the StreamBase application's logging system with a loglevel of TRACE.
| ||
| LogWarn(String) |
Sends the given string to the StreamBase application's logging system with a loglevel of WARN.
| ||
| ProcessTuple(Int32, Tuple) |
This is called whenever the .NET Operator receives a tuple to be processed
by the .NET client code.
This method should not be made to block as this will interrupt the tuple flow through the .NET Operator,
potentially hanging the StreamBase application in part or in whole.
The client code may wish to thow a StreamBaseException if something goes wrong;
this exception will be passed along to the Operator for proper logging in the application.
| ||
| Resume()()()() |
This is called when an operator starts or resumes execution.
Note that if the application is shutdown directly from a suspended state, this will
NOT be called; instead Shutdown()()()() will be called.
Resume()()()() is a callback that is called by the StreamBase runtime.
Exceptions thrown during calls to Resume()()()() will be logged via
LogError(String), processed as error tuples, and trigger
a shutdown of the operator.
| ||
| SendErrorOutput(Exception) |
Sends an error tuple from this operator's error port.
This method will also record the message in the debug log.
| ||
| SendErrorOutput(String) |
Sends an error tuple from this operator's error port.
This method will also record the message in the debug log.
| ||
| SendErrorOutput(Exception, Int32, Tuple) |
Sends an error tuple from this operator's error port.
This method will also record the message in the debug log.
| ||
| SendOutput(Int32, Tuple) |
Sends the given tuple to the given output port of the .NET Operator
for use by the application.
If the given tuple is created by this operator then it can be reused when
the call to SendOutput() returns, as the application is done with the tuple at that point.
| ||
| SendOutputAsync(Int32, Tuple) |
Enqueues a Tuple to be sent asynchronously to downstream operators.
All calls to SendOutputAsync(Int32, Tuple) are well ordered with
respect to other calls to SendOutputAsync(Int32, Tuple), meaning
that downstream logic will receive the tuples in the order they are sent.
Calls to SendOutputAsync(Int32, Tuple) and SendOutput(Int32, Tuple)
are not well ordered with respect to each other, meaning calls from the
two methods can be received downstream in any order.
| ||
| Shutdown()()()() |
This is called by the StreamBase runtime just prior to shutting down
this Operator. An implementation of shutdown should include any behavior
needed to shut down the Operator - freeing resources, etc.
Shutdown()()()() is a callback that is called by the StreamBase runtime.
| ||
| Suspend()()()() |
This is called when an operator is suspended.
Suspend()()()() is a callback that is called by the StreamBase runtime.
Exceptions thrown during calls to Resume()()()() will be logged via
LogError(String) and processed as error tuples.
| ||
| ToString()()()() | Returns a string that represents the current object. (Inherited from Object.) |
