static String |
translateVariables(String expression,
OgnlValueStack stack,
TextParseUtil.ParsedValueEvaluator evaluator)
Function similarly as translateVariables(char, String, OgnlValueStack)
except for the introduction of an additional evaluator that allows
the parsed value to be evaluated by the evaluator . |

public static String translateVariables(String expression, OgnlValueStack stack)
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.
expression
- an expression that hasn't yet been translated
public static String translateVariables(String expression, OgnlValueStack stack, TextParseUtil.ParsedValueEvaluator evaluator)
translateVariables(char, String, OgnlValueStack)
except for the introduction of an additional evaluator
that allows
the parsed value to be evaluated by the evaluator
. The evaluator
could be null, if it is it will just be skipped as if it is just calling
translateVariables(char, String, OgnlValueStack)
.
A typical use-case would be when we need to URL Encode the parsed value. To do so
we could just supply a URLEncodingEvaluator for example.
expression
- stack
- evaluator
- The parsed Value evaluator (could be null).
