Method Detail

addChangeListener

public void addChangeListener(org.jfree.data.general.DatasetChangeListener l)

Specified by:

addChangeListener in interface org.jfree.data.general.Dataset

removeChangeListener

public void removeChangeListener(org.jfree.data.general.DatasetChangeListener l)

Specified by:

Specified by:

getGroup in interface org.jfree.data.general.Dataset

setGroup

public void setGroup(org.jfree.data.general.DatasetGroup g)

Specified by:

setGroup in interface org.jfree.data.general.Dataset

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".
