Operators operators
There are two kinds of operators: unary operators and binary operators. There are left-hand unary operators and right-hand unary operators.
// left-hand unary operators
// <operator> <operand>
// operand is an expression
not (@event{LobbyBeacon.endUserIDs._experience.emailid.id}=="example@adobe.com")
// right-hand unary operators
// <operator> <operand>
// operand is an expression
@event{LobbyBeacon.endUserIDs._experience.emailid.id} is not null
// binary operators
// <operand1> <operator> <operand2>
// operand is an expression
(@event{LobbyBeacon.endUserIDs._experience.emailid.id}=="example1@adobe.com") or (@event{LobbyBeacon.endUserIDs._experience.emailid.id}=="example2@adobe.com")
Important notes important-notes
-
When using a multiplication (
*), both operation fields must have the same type, either integer or decimal. Example :- the following example is correct:
3.0 * 4.0 3 * 4.0will lead to an error
- the following example is correct:
Logical logical
and
<expression1> and <expression2>
Both <expression1> and <expression2> must be boolean. The result is boolean.
Example:
3.14 > 2 and 3.15 < 1
or
<expression1> or <expression2>
Both <expression1> and <expression2> must be boolean. The result is boolean.
Example:
3.14 > 2 or 3.15 < 1
not
not <expression>
<expression> must be boolean. The result is boolean.
Example:
not 3.15 < 1
Comparison comparison
is null
<expression> is null
The result is boolean.
Note that null means the expression has no evaluated value.
Example:
@event{BarBeacon.location} is null
is not null
<expression> is not null
The result is boolean.
Note that null means the expression has no evaluated value.
Example:
@event{BarBeacon.location} is not null
has null
<expression> has null
<expression> must be a list. The result is boolean.
Useful to identify that a list contains at least one null value.
Example:
["foo", "bar", null] has null
Returns true
["foo", "bar", ""] has null
Returns false because “” is not considered as null.
==
<expression1> == <expression2>
Example:
3.14 == 42
"foo" == "bar"
!=
<expression1> != <expression2>
The result is boolean.
Example:
3.14 != 42
"foo" != "bar"
>
<expression1> > <expression2>
Datetime can be compared with Datetime.
Datetimeonly can be compared with Datetimeonly.
Both integer or decimal can be compared with both integer or decimal.
Any other combination is forbidden.
The result is boolean.
Example:
3.14 > 42
>=
<expression1> >= <expression2>
Datetime can be compared with Datetime.
Datetimeonly can be compared with Datetimeonly.
Both integer or decimal can be compared with both integer or decimal.
Any other combination is forbidden.
The result is boolean.
Example:
42 >= 3.14
<
<expression1> < <expression2>
Datetime can be compared with Datetime.
Datetimeonly can be compared with Datetimeonly.
Both integer or decimal can be compared with both integer or decimal.
Any other combination is forbidden.
The result is boolean.
Example:
42 < 3.14
<=
<expression1> <= <expression2>
Datetime can be compared with Datetime.
Datetimeonly can be compared with Datetimeonly.
Both integer or decimal can be compared with both integer or decimal.
Any other combination is forbidden.
The result is boolean.
Example:
42 <= 3.14
Arithmetic arithmetic
+
<expression1> + <expression2>
Both expressions must be numeric (integer or decimal).
The result is also numeric.
Example:
1 + 2
Returns 3
-
<expression1> - <expression2>
Both expressions must be numeric (integer or decimal).
The result is also numeric.
Example:
2 - 1
Returns 1
/
<expression1> / <expression2>
Both expressions must be numeric (integer or decimal).
The result is also numeric.
<expression2> must not be equal to 0 (returns 0).
Example:
4 / 2
Returns 2
*
<expression1> * <expression2>
Both expressions must be numeric (integer or decimal).
The result is also numeric.
Example:
3 * 4
Returns 12
%
<expression1> % <expression2>
Both expressions must be numeric (integer or decimal).
The result is also numeric.
Example:
3 % 2
Returns 1.
Math math
is numeric
<expression> is numeric
The type of the expression is integer or decimal.
Example:
@ is numeric
is integer
<expression> is integer
The type of the expression is integer.
Example:
@ is integer
is decimal
<expression> is decimal
The type of the expression is decimal.
Example:
@ is decimal
String string
+
<string> + <expression>
<expression> + <string>
It concatenates two expressions.
One expression must be a chained string.
Example:
"the current time is " + (now())
Returns “the current time is 2019-09-23T09:30:06.693Z”
(now()) + " is the current time"
Returns “2019-09-23T09:30:06.693Z is the current time”
"a" + "b" + "c" + 1234
Returns “abc1234”.
Date date
+
<expression> + <duration>
Append a duration to a dateTime, a dateTimeOnly or a duration.
Example:
(toDateTime("2011-12-03T15:15:30Z")) + (toDuration("PT15M"))
Returns a dateTime 2011-12-03T15:30:30Z
(toDateTimeOnly("2011-12-03T15:15:30")) + (toDuration("PT15M"))
Returns a dateTimeOnly 2011-12-03T15:30:30
(now()) + (toDuration("PT1H"))
Returns a dateTime (with UTC time zone) one hour later from current time
(toDuration("PT1H")) + (toDuration("PT1H"))
Returns a duration PT2H
