Henri Biestro updated JEXL-423:
-------------------------------
Description:
The {code:java} instanceof {code}
operator allows to check whether an object belongs to a certain class.
It is using Class.isInstance to perform the check. As a convenience, {{
!instanceof }} is supported as well avoiding parenthesis as in:
{code:java}x !instanceof y{code} is equivalent to {code:java} !(x instanceof
y){code}
was:
