Operator

Description

Notes

Boolean and

The usual && operator can be used as well as the word and, e.g.

cond1 and cond2

and

cond1 && cond2

are equivalent

Boolean or

The usual || operator can be used as well as the word or, e.g.

cond1 or cond2

and

cond1 || cond2

are equivalent

Boolean not

The usual ! operator can be used as well as the word not, e.g.

!cond1

and

not cond1

are equivalent

Bitwise and

The usual | operator is used, e.g.

33 | 4

, 0010 0001 | 0000 0100 = 0010 0101 = 37.

Bitwise xor

The usual ^ operator is used, e.g.

33 ^ 4

, 0010 0001 ^ 0000 0100 = 0010 0100 = 37.

Bitwise complement

The usual ~ operator is used, e.g.

~33

, ~0010 0001 = 1101 1110 = -34.

Ternary conditional ?:

The usual ternary conditional operator condition ? if_true : if_false operator can be used as well as the abbreviation value ?: if_false which returns the value if its evaluation is defined, non-null and non-false, e.g.

val1 ? val1 : val2

and

val1 ?: val2

are equivalent.

NOTE: The condition will evaluate to false when it refers to an undefined variable or null for all JexlEngine flag combinations. This allows explicit syntactic leniency and treats the condition 'if undefined or null or false' the same way in all cases.

Equality

The usual == operator can be used as well as the abbreviation eq. For example

val1 == val2

and

val1 eq val2

are equivalent.

null is only ever equal to null, that is if you compare null to any non-null value, the result is false. Equality uses the java equals method

Inequality

The usual != operator can be used as well as the abbreviation ne. For example

val1 != val2

and

val1 ne val2

are equivalent.

Less Than

The usual < operator can be used as well as the abbreviation lt. For example

val1 < val2

and

val1 lt val2

are equivalent.

Less Than Or Equal To

The usual <= operator can be used as well as the abbreviation le. For example

val1 <= val2

and

val1 le val2

are equivalent.

Greater Than

The usual > operator can be used as well as the abbreviation gt. For example

val1 > val2

and

val1 gt val2

are equivalent.

Greater Than Or Equal To

The usual >= operator can be used as well as the abbreviation ge. For example

val1 >= val2

and

val1 ge val2

are equivalent.

In or Match=~

The syntactically Perl inspired =~ operator can be used to check that a string matches a regular expression (expressed either a Java String or a java.util.regex.Pattern). For example "abcdef" =~ "abc.* returns true. It also checks whether any collection, set or map (on keys) contains a value or not; in that case, it behaves as an "in" operator. Note that it also applies to arrays as well as "duck-typed" collection, ie classes exposing a "contains" method. "a" =~ ["a","b","c","d","e",f"] returns true.

Not-In or Not-Match!~

The syntactically Perl inspired !~ operator can be used to check that a string does not match a regular expression (expressed either a Java String or a java.util.regex.Pattern). For example "abcdef" !~ "abc.* returns false. It also checks whether any collection, set or map (on keys) does not contain a value; in that case, it behaves as "not in" operator. Note that it also applies to arrays as well as "duck-typed" collection, ie classes exposing a "contains" method. "a" !~ ["a","b","c","d","e",f"] returns true.

Addition

The usual + operator is used. For example

val1 + val2

Subtraction

The usual - operator is used. For example <pre> val1 - val2 </pre> | |- |Multiplication |<nowiki>The usual / operator is used, or one can use the div operator. For example

val1 / val2

or

val1 div val2

Modulus (or remainder)

The % operator is used. An alternative is the mod operator. For example

5 mod 2

gives 1 and is equivalent to

5 % 2

Negation

The unary - operator is used. For example<nowiki> <pre> -12 </pre> | |- |Array access |<nowiki>Array elements may be accessed using either square brackets or a dotted numeral, e.g.

arr1[0]

and

arr1.0

are equivalent

HashMap access

Map elements are accessed using square brackets, e.g.

map[0]; map['name']; map[var];

Note that

map['7']

and

map[7]

refer to different elements. Map elements with a numeric key may also be accessed using a dotted numeral, e.g.

map[0]

and

map.0

are equivalent.
