Expression, Operand

<> judges if a given <value> is in a closed interval between <lower> and <upper>, with <value> greater than or equal to <lower> but less than or equal to <upper>. It only makes sense when <lower> is less than or equal to <upper>.

Syntax:

• Expression: <value> <=> [<lower>, <upper>]
• Operand: ATTR (string, number, time)

Constant

Example: judge if "abc" is in the closed interval ["asd", "1af"]

return "abc" <=> ["asd", "1af"]

Function

Example: judge if PI is in the closed interval [3.14, 3.15]

uncollect [3.14, 3.15] as a
with collect(a) as b
return pi() <=> [b[0], b[1]]

Alias

Example: find 10 nodes whose levels are in the closed interval [1, 3]

find().nodes() as n
where n.level <=> [1, 3]
limit 10
return n{*}

Property

Example: find 10 nodes whose levels are in the closed interval [1, 3]

find().nodes({level <=> [1, 3]}) as n
limit 10
return n{*}
