translateVariables

public static String translateVariables(String expression,
                                        OgnlValueStack stack)

Converts all instances of ${...} in expression to the value returned by a call to OgnlValueStack.findValue(java.lang.String). If an item cannot be found on the stack (null is returned), then the entire variable ${...} is not displayed, just as if the item was on the stack but returned an empty string.

Returns:

the parsed expression
