T
- the type of object represented in this data resourcepublic interface IDataSource<T>
An object that mediate between an IDataSourceDictionary
and the data
that is contained in the dictionary data resources. Data resources are
assigned a name (e.g., verb.data, for the data resource pertaining to
verbs) and a content type. Data resources are assumed to be indexed by keys
that can be passed into the getLine(String)
method to find a
particular piece of data in the resource. The String
return can
be parsed by the parser associated with the content type to produce a data
object (e.g., an ISynset
or IIndexWord
object).
The iterator produced by this class should not support the
Iterator.remove()
operation; if that method is called, the iterator
will throw an UnsupportedOperationException
.

, this is the same as calling the plain

operation; if
that method is called, the iterator will throw an
