OneSampleBuffer

One sample buffer for control signals.

This is primarily meant to handle default values for multi-channel user-provided control signals that update at most once per tick (i.e., there is only one sample per tick). The initial value of the control signal is sourced from the initi_values argument, and thereafter the initial value is optionally updated based on the data of the input signal. There is a distinct 'null' value, which will not override the default values, to allow users to override the defaults only partially. Version 1.0.0

Ports/Properties

data

Data to process.

  • verbose name: Data
  • default value: None
  • port type: DataPort
  • value type: Packet (can be None)
  • data direction: INOUT

initial_values

These values are the initial values assigned to the output. The dict use channel names as the key values.

  • verbose name: Initial Values
  • default value: None
  • port type: DictPort
  • value type: dict (can be None)

null_value

The null value. If the input signal contains this value in any of its channels, the current value in the buffer will not be updated.

  • verbose name: Null Value
  • default value: nan
  • port type: FloatPort
  • value type: float (can be None)

set_breakpoint

Set a breakpoint on this node. If this is enabled, your debugger (if one is attached) will trigger a breakpoint.

  • verbose name: Set Breakpoint (Debug Only)
  • default value: False
  • port type: BoolPort
  • value type: bool (can be None)

metadata

User-definable meta-data associated with the node. Usually reserved for technical purposes.

  • verbose name: Metadata
  • default value: {}
  • port type: DictPort
  • value type: dict (can be None)
