Overview

   This factory is used to filter input features based on the type of geometry they contain.

Clauses

  FILTER_TYPES
  A comma delimited list of geometry types to filter.
  An output port will be created for each type listed.

  INSTANCES
  This parameter determines how Geometry Instances should be filtered.
      INSTANCE
         Filter geometry instances as their own type. They will be output the
         Geometry Instance port if Geometry Instance is included in FILTER_TYPES,
         otherwise UNFILTERED.
      CAST
         Filter geometry instances based on the type of their definition, without instantiating.
      INSTANTIATE
         Instantiate geometry instances before filtering.

  BREAK_AGG
  If enabled, aggregates will be recursively split into homogeneous multis/aggregates before
filtering. Any resulting aggregates will be output through the port corresponding to the type of
their children.

Output Tags

   UNFILTERED

   Features that containing geometry types not specified in the
   FILTER_TYPES clause will be output the unfiltered port.

   <geometry type>

   Any geometry type specified in the FILTER_TYPES clause will have a corresponding
   output tag that will output features containing geometry of that type.
