23 | * This class has predefined instances that stand for OGNL's special "dynamic subscripts" for getting at the first, | |
24 | * middle, or last elements of a list. In OGNL expressions, these subscripts look like special kinds of array indexes: | |
25 | * [^] means the first element, [$] means the last, [|] means the middle, and [*] means the whole list. | |
