Detect Expression Language
Introduction
The HCL
Detect Expression Language
is a simple expression language used to specify filter conditions and basic arithmetic
manipulations. It can be used as part of configuring triggers. In particular, a trigger's
WHEN
condition can have a free-form expression specified as part of a
predicate's right hand-side. Similarly, a trigger's THEN
action can have
an expression specified as an assignment for an output attribute. These expressions are
specified in HCL
Detect Expression Language.
