public class TermCodes extends Object
This class is used for assigning codes to terms as we index a document collection.
It makes use of two properties from the default properties file. The first one is termcodes.initialcapacity, which specifies the initial capacity of the used hash map. The default value is 3000000.
The second property is termcodes.garbagecollect, which enables or disables garbage collection during the call of the method reset(). The default value is true.
