Method Detail

addChangeListener

public void addChangeListener(DatasetChangeListener l)

removeChangeListener

public void removeChangeListener(DatasetChangeListener l)

getGroup

public DatasetGroup getGroup()

setGroup

public void setGroup(DatasetGroup g)

setKeyValue

public void setKeyValue(int keyCol,
                        int valueCol)
                 throws IllegalArgumentException,
                        IllegalStateException,
                        QueryParseException

Throws:

IllegalArgumentException

IllegalStateException

QueryParseException

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: Query.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".

public int getItemCount()

getValue

public Number getValue(int index)

getIndex

public int getIndex(Comparable k)
