public void addChangeListener(DatasetChangeListener l)

removeChangeListener

public void removeChangeListener(DatasetChangeListener l)

getGroup

public DatasetGroup getGroup()

getResults

public QueryResults getResults()

Get any results, will be null unless Query.execute(List) has been called.

Returns:

The results.

clearResults

public void clearResults()

Clear any results.

setGroup

public void setGroup(DatasetGroup g)

define

public void define(int xCol,

            throws IllegalArgumentException,
                   IllegalStateException,
                   QueryParseException

Throws:

executeQuery

public QueryResults executeQuery(List l)
                          throws QueryExecutionException

Exectute the query and return the results. A reference to the results is also held to allow them to be iterated over. If you plan on re-using this data source then you should call: clearResults() to free up the references to the results.

Parameters:

l - The List of objects to execute the query on.

Returns:

The results.

Throws:

QueryExecutionException - If the query cannot be executed, or if the query is set to return objects rather than "columns".
