20 | * Converts a String to a Boolean. Strings that do contain non-whitespace are considered true. As a | |
21 | * special case, the string "false" evaluates to false (this allow boolean component parameters to | |
22 | * be bound to "false" instead of "ognl:false" and still operate as expected). | |
