Description copied from interface:StringLookup
Looks up a String key to provide a String value.The internal implementation may use any mechanism to return the value. The simplest implementation is to use a Map. However, virtually any implementation is possible.
For example, it would be possible to implement a lookup that used the key as a primary key, and looked up the value on demand from the database Or, a numeric based implementation could be created that treats the key as an integer, increments the value and return the result as a string - converting 1 to 2, 15 to 16 etc.
This method always returns a String, regardless of the underlying data, by converting it as necessary. For example:
Map<String, Object> map = new HashMap<String, Object>(); map.put("number", new Integer(2)); assertEquals("2", StringLookupFactory.mapStringLookup(map).lookup("number"));
- Parameters:
key
- the key to look up, may be null.- Returns:
- The matching value, null if no match.
