Filters

Overview

Filters can be used for explicit object matching, as well as members of Stream and Action objects, where they control the types of Event that can enter an Action or Stream.

Note that regular expressions in these filters follow the Java regex format.

Filter Operations

Attribute Value	attribute < <= == > >= != value	path == '/streamPath' location.lat > 43.535635 elems.arbitraryAttribute != false
Attribute Comparison	attribute1 < <= == > >= != attribute2	path == description elems.attribute1 >= elems.attribute2
Modulo	attribute1 % X (== OR !=) Y	elems.counter % 100 == 0
IN	attribute IN ["value1", "value2", "value3"]	elems.status IN ["shipped", "delivered"]
CONTAINS	attribute CONTAINS ["value1", "value2", "value3"]	elems.ingredients CONTAINS ["potato", "salad"]
