Detailed Description

AD plugin that saves attribute values from recieved NDArrays.

The plugin caches last attributes values in and exposes the selected ones periodically to the EPICS layer in waveform records. The plugin only works with numerical Attributes. The type of the attribute is discarded, all attributes are interpreted as doubles.

The attributes are read from the NDArray on the first frame of acquisition and populated in first come first served fashion (unpredictable order). On reset or reacquistion the cache is cleared and all data is discarded.

Constructor & Destructor Documentation

◆ NDPluginAttrPlot()

NDPluginAttrPlot::NDPluginAttrPlot ( const char *  port,

const char *  in_port,
int  in_addr,
int  queue_size,
int  blocking_callbacks,
int  priority,
int  stackSize 
)

Constructor.

Parameters
portPort name of the plugin.
max_attributesMaximum number of Y1 attributes to save.
cache_sizeSize of the cache for an attribute.
max_selectedMaximum number of selected Y1 attributes.
in_portPort from where the NDArrays are recieved.
in_addrAddress from where the NDArrays are recieved.
queue_sizeSize of the NDArray callback queue.
blocking_callbacksShould blocking callbacks be used.
priorityPriority of the internal thread.
stackSizeStack size for the internal thread.

Member Function Documentation

◆ processCallbacks()

void NDPluginAttrPlot::processCallbacks ( NDArray pArray)
virtual

Caches the values of attributes in the array.

Also resets the driver if the UID of the NDArray is lower than the last cached one.

Parameters
pArrayThe NDArray from the callback.

Implements NDPluginDriver.

◆ start_expose()

void NDPluginAttrPlot::start_expose ( )

Starts the data exposure task.

◆ writeInt32()

asynStatus NDPluginAttrPlot::writeInt32 ( asynUser *  pasynUser,
epicsInt32  value 
)
virtual

Called when an OUT record with asynInt32 interface is processed.

Parameters
pasynUserStructure that encodes the reason and address.
valueValue to write.

Reimplemented from NDPluginDriver.
