Method Details

lookup

public String lookup(String variable)

Looks up a String key to 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.

The StrLookup.lookup(String) method always returns a String, regardless of the underlying data, by converting it as necessary. For example:

 Map map = new HashMap();
 map.put("number", new Integer(2));
 assertEquals("2", StrLookup.mapLookup(map).lookup("number"));
 

Specified by:

lookup in class StrLookup

Parameters:

variable - the key to be looked up, may be null

Returns:

the matching value, null if no match

put

public void put(String var,
 String replace)

Adds or overwrites a mapping of this replacer.

Parameters:

var - name of the variable to map

replace - the value of the variable
