Constructor Detail

DsPropertyCollection

public DsPropertyCollection(String dataSourceId,
                            Connection connection,
                            ResultSet resultSet)

Default constructor.

Parameters:

dataSourceId - the identifier of the data source the properties are read from.

connection - the underlying connection of the result set.

resultSet - the properties to iterate over.

Method Detail

iterator

public Iterator<Property> iterator()

Returns an iterator over a set of properties.

Please note that an implementation may require to call PropertyCollection.close() after iterating over the values. The client calling PropertyCollection.iterator() is responsible for closing the collection.
