Trim

Trim removes a set of characters from the beginning and end of a metadata value or the payload.

Parameters

Characters (default: trnvf)

This value defines which characters should be removed from both ends of the data. The data to operate on is expected to be a string. By default this is set to ” trnvf”.

Parameters (from core.SimpleFormatter)

Source

This value chooses the part of the message the data to be formatted should be read from. Use “” to target the message payload; other values specify the name of a metadata field to target. By default this parameter is set to “”.

Target

This value chooses the part of the message the formatted data should be stored to. Use “” to target the message payload; other values specify the name of a metadata field to target. By default this parameter is set to “”.

ApplyTo

Use this to set Source and Target to the same value. This setting will be ignored if either Source or Target is set to something else but “”. By default this parameter is set to “”.

SkipIfEmpty

When set to true, this formatter will not be applied to data that is empty or - in case of metadata - not existing. By default this parameter is set to false
