Builds an AQL expression that checks whether a given value is a boolean.


    
                    isBool(string $value) : string

This helper wraps the ArangoDB AQL function IS_BOOL() and returns a string representation of that expression.

The AQL function IS_BOOL(value) returns true if the provided value is a boolean (true or false), and false otherwise.

Example output:

IS_BOOL(doc.isActive)

$value : string: The AQL field or expression to check (e.g. 'doc.isActive').

example

use function oihana\arango\db\functions\isBool;

$expr = isBool('doc.isActive');
// Produces: 'IS_BOOL(doc.isActive)'
