SelectInstanceFields

Select (retain) or drop fields from an instance axis.

This can be used to drop extraneous variables from instance axes that may otherwise be included automatically by some nodes (i.e., plot nodes). Note that this will act on all instance axes found in all streams (except for marker streams if include_markers is False). Note that dropping (or adding) fields to the instance axis does not change the number of elements (items) along the instance axis, (rather these fields act as attributes of each element along the instance axis), and therefore does not change the shape of the data tensor in a stream. 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

retain_fields

Fields in the instance axis to select; all other fields will be dropped. An empty list will drop all fields. Note however that the 'Marker', 'TargetValue', and 'IsGood' fields cannot be dropped so in that case their values will be set to null instead.

  • verbose name: Fields To Select
  • default value: ['Marker', 'TargetValue', 'IsGood']
  • port type: ListPort
  • value type: list (can be None)

inverse_selection

Inverse the selection. If True, the fields listed in retain_fields will be dropped and all others present in the instance axis will be retained.

  • verbose name: Inverse Selection
  • default value: False
  • port type: BoolPort
  • value type: bool (can be None)

include_markers

Also select (or drop) fields from marker streams. If false, only signal streams are processed.

  • verbose name: Include Markers
  • default value: False
  • port type: BoolPort
  • value type: bool (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)
