FilterConditionArtifact

Summary

This block is used to filter the elements of an artifact based on a condition. The filtered artifact will then be used in the following blocks.

Implementation

• Drag and drop the block from the palette

• Link the "execute" action from the "executed" topic of the previous block

Example

This block is based on a previous artifacts that retrieved some points. It will filter the points to keep only the ones of BooleanWritable type.

 Properties

• Artifacts: Artifacts created by this block. Be careful, the artifact is an array, you will need sometimes to use .first in a SFormat to use it.

• Target: SFormat to define the target (queries, ord, artifacts etc.)

• Parameter1: SFormat to define the first parameter of the condition.

• Operator { Exists, Equals, NotEquals, Like }: To define how the first and the second parameter should be compared. Both parameters are reduced as a String before being compared.

  • Exists: Checks that the value defined in the first parameter exists. The second parameter is useless in this case

  • Equals: Checks that both parameters are equal

  • NotEquals: Checks that both parameters are different

  • Like: Checks that the first parameter is like a pattern described in the second parameter. Wildcards * can be used (it's not a regex as with NEQL queries).

• Parameter2: SFormat to define the second parameter of the condition. 

Behavior: DO & UNDO

An artifact will be created.
