Struct AttributeProcessor 

pub struct AttributeProcessor { /* private fields */ }

Processor that extracts multiple attribute values from each array.

Implementations

impl AttributeProcessor

pub fn new(attr_name: &str) -> Self

pub fn set_ts_sender(&mut self, sender: TimeSeriesSender)

pub fn params(&self) -> &AttributeParams

Access the registered param indices (populated after register_params).

pub fn reset(&mut self, addr: usize)

Reset the accumulated sum for a channel.

pub fn value(&self) -> f64

Current extracted value for channel 0.

pub fn value_sum(&self) -> f64

Current accumulated sum for channel 0.

pub fn attr_name(&self) -> &str

The attribute name being tracked by channel 0.

pub fn set_attr_name(&mut self, name: &str)

Set the attribute name for channel 0.

Trait Implementations

impl NDPluginProcess for AttributeProcessor

fn process_array( &mut self, array: &NDArray, _pool: &NDArrayPool, ) -> ProcessResult

Process one array. Return output arrays and param updates.

fn plugin_type(&self) -> &str

Plugin type name for PLUGIN_TYPE param.

fn register_params( &mut self, base: &mut PortDriverBase, ) -> Result<(), AsynError>

Register plugin-specific params on the base. Called once during construction.

fn on_param_change( &mut self, reason: usize, params: &PluginParamSnapshot, ) -> ParamChangeResult

Called when a param changes. Reason is the param index. Return param updates to be written back to the port driver.

fn array_data_handle( &self, ) -> Option<Arc<Mutex<RawMutex, Option<Arc<NDArray>>>>>

Return a handle to the latest NDArray data for array reads. Override this in plugins like NDPluginStdArrays that serve pixel data via readInt8Array/readInt16Array/etc.
