public class NotEmptyVar
extends SimpleVar

Upper-case variable resolver.

The format for this var is "$NE{stringValue}".

This variable returns "true" if the contents are not empty.

Since this is a SimpleVar, any variables contained in the result will be recursively resolved. Likewise, if the arguments contain any variables, those will be resolved before they are passed to this var.
