Examples of com.sun.jsftemplating.el.PermissionChecker

com.sun.jsftemplating.el.PermissionChecker
This class evaluates a Boolean equation. The supported functions / operators are:
- $<type>{<key>} -- To read a value according to <type> using <key> (See: {@link VariableResolver}). (null is interpretted as false, non boolean values (besides the string "false") are interpretted to mean true)
- '(' and ')' can be used to override order of operation
- '!' negate a boolean value
- '|' logical OR
- '&' logical AND
- '=' String equals
- '<' less than between 2 Integers
- '>' greater than between 2 Integers
- '%' modulus of 2 Integers
Operator Precedence (for infix notation) is:
- () -- Highest
- !
- %
- &
- |
- < and >
- =
