What's Changed

• Documented and fixed a bug with using quoted structure element names. Handling of element names that contain spaces.

Full Changelog: 3.0.3...3.0.4

Structure elements containing spaces in name

If your structure has element names that contain spaces, you can use double quotes in the expression to access them.

Map<String, Object> data = new HashMap<>();
data.put("property 1", 12345);

Expression expression = new Expression("data.\"property 1\"")
    .with("data", data);

BigDecimal result = expression.evaluate().getNumberValue();

System.out.println(result); // prints 12345

This also works with arrays.

Map<String, Object> data = new HashMap<>();
data.put("property 1", Arrays.asList(1, 2, 3));

Expression expression = new Expression("data.\"property 1\"[1]")
    .with("data", data);

BigDecimal result = expression.evaluate().getNumberValue();

System.out.println(result); // prints 2
