Reject
This Capture layer rejects or hides the current frame if certain conditions are met.
A rejected frame is not stored in the database. A hidden frame is stored, but is marked as 'hidden' so it will not be included in downloads.
Parameters
| Name | Default | Meaning |
|---|---|---|
| if | Optional - if true, the frame is rejected | |
| required | Optional - a list of strings. The frame must contain all of these attribute names. | |
| action | ignore | Either ignore or hide. |
Description
This function rejects or hides captures based on conditions.
This is normally used to filter out bad data - for example, unusually short product batches, times when no data was available, or setting reasonable limits on values.
Note that you ignore a frame, all processing will stop (later layers won't be run). If you hide a frame, the later layers will still be processed as normal.
Example
{ "type": "reject", "required": ["Machine.Speed"], "action": "ignore" }
The layer will not record the capture unless it contains the attribute 'Machine.Speed'.
{ "type": "reject", "if": "{Duration} < 120", "action": "hide" }
The layer will hide the capture if it takes less than 2 minutes.
