void SampleOutputBase::addParameter ( Parameter val)
inherited

Add a parameter to this DSMSensor.

DSMSensor will then own the pointer and will delete it in its destructor. If a Parameter exists with the same name, it will be replaced with the new Parameter.

void CVIOutput::addRequestedSampleTag ( SampleTag tag)
throw (nidas::util::InvalidParameterException
)
virtual

Some SampleOutputs don't send out all the Samples that they receive.

At configuration time, one can use this method to request the SampleTags that should be output from a SampleOutput. SampleOutput will own the pointer.

Reimplemented from nidas::core::SampleOutputBase.

References nidas::core::SampleOutputBase::addRequestedSampleTag(), nidas::core::VariableIterator::hasNext(), and nidas::core::VariableIterator::next().

void SampleOutputBase::addSourceSampleTag ( const SampleTag tag)
throw (nidas::util::InvalidParameterException
)
virtualinherited

Some SampleOutputs like to be informed of what SampleTags they will be receiving from their SampleSources before they make a connection.

Users of SampleOutputs should call this method before calling requestConnection().

Implements nidas::core::SampleOutput.

Reimplemented in nidas::dynld::isff::GOESOutput.

void CVIOutput::derivedDataNotify ( const DerivedDataReader s)
throw (
)
virtual

Method called on a DerivedDataClient by the DerivedDataReader thread when a new packet of derived data has been received.

This method is called on the DerivedDataClients in the sequence that they registered with the DerivedDataReader. The implementation of this method in a client should run quickly, to reduce the delay in calling successive clients in the list.

Implements nidas::core::DerivedDataClient.

void SampleOutputBase::disconnect ( )
throw (nidas::util::IOException
)
protectedinherited

Close the IOChannel and notify whoever did the requestConnection that it is time to disconnect, perhaps because of an IOException.

This is typically called in the receive() method of a SampleOutput if it gets an IOException when writing data. A common implementation of a connection requester is to delete this SampleOutput after the removing it from the sample stream. So the caller method should immediately return after calling disconnect().

Get pointer to SampleOutput that was cloned.

Implements nidas::core::SampleOutput.

Fetch a parameter by name.

Returns a NULL pointer if no such parameter exists.

Get list of parameters.

Base class implementation.

If setReconnectDelaySecs() has been called on this SampleOutput, then that value will be returned. Otherwise this will return the value of the IOChannel.

Method called to pass a sample to this client.

This method is typically called by a SampleSource for each of its SampleClients when it has a sample ready. Returns true: success false: sample rejected. This is meant to signal a warning-type situation - like a socket not being available temporarily. True errors will be thrown as an IOException.

Implements nidas::core::SampleClient.

void CVIOutput::requestConnection ( SampleConnectionRequester requester)
throw (
)
virtual

Request a connection, but don't wait for it.

Requester will be notified via SampleConnectionRequester interface when the connection has been made. It is not necessary to call this method if a SampleOutput is constructed with a connected IOChannel.

void nidas::core::SampleOutputBase::setLatency ( float  val)

Set desired latency, providing some control over the response time vs buffer efficiency tradeoff.

Setting a latency of 1/10 sec means buffer data in the IOStream for a 1/10 sec, then send the data to the physical device.

Parameters
valLatency, in seconds.
