Properties

Property	Details
excludedEffect	The effect applied to features that do not meet the filter requirements.
filter	The client-side filter executed on each displayed feature to determine which of includedEffect or excludedEffect to apply. See filter properties table.
includedEffect	The effect applied to features that meet the filter requirements.

Property	Details
where	A SQL-based where clause that narrows the data to be used. Any features that satisfy the query will be used.
