Event filters are based on the information in the event data.
Both event data and event message data can be saved as process data.
Create
event filters for event catches, receives, and start points to specify
the conditions under which the event is acted on when the event
occurs. An event filter specifies criteria on event data or event
message data. An event filter can one or more filter expressions
and all expressions must evaluate to True for an event to be acted
on.
Note:
If no filters are created for an event, the
event is always acted on.
Event filters consist of expressions in the following form:
expression1 operator expression2
-
expression1
is an XPath expression that
evaluates to a filter key or a value in the process data tree.
-
operator
is an arithmetic operator that
you choose.
-
expression2
is an XPath expression that
evaluates to a literal value or a value in the process data tree.
In the following example event filter, if the
creditscore
filter
key contains a value greater than
800
, the filter
resolves to
True
:
/data/applicants/Applicant/creditscore > 800
