Interface RolapResult.ValueFormatter

All Known Implementing Classes:

RolapResult.CellFormatterValueFormatter, RolapResult.FormatValueFormatter

Enclosing class:

RolapResult

static interface RolapResult.ValueFormatter

Formatter to convert values into formatted strings.

Every Cell has a value, a format string (or CellFormatter) and a formatted value string. There are a wide range of possible values (pick a Double, any Double - its a value). Because there are lots of possible values, there are also lots of possible formatted value strings. On the other hand, there are only a very small number of format strings and CellFormatter's. These formatters are to be cached in a synchronized HashMaps in order to limit how many copies need to be kept around.

There are two implementations of the ValueFormatter interface:

• RolapResult.CellFormatterValueFormatter, which formats using a user-registered CellFormatter; and
• RolapResult.FormatValueFormatter, which takes the Locale object.
