Method Detail

reconfigure

public DatasetSpecification reconfigure(String instanceName,
                                        DatasetProperties newProperties,
                                        DatasetSpecification currentSpec)
                                 throws IncompatibleUpdateException

Description copied from interface: Reconfigurable

Validates the new properties, including a compatibility check with the existing spec, and returns a new dataset specification for the dataset instance.

Specified by:

reconfigure in interface Reconfigurable

Overrides:

reconfigure in class CompositeDatasetDefinition<CounterTimeseriesTable>

newProperties - the updated dataset properties, to be validated by this method

currentSpec - the current specification of the dataset

Returns:

a new dataset specification, created from the new properties

Throws:

IncompatibleUpdateException - if the new properties are not compatible with the existing dataset

getDataset

public CounterTimeseriesTable getDataset(DatasetContext datasetContext,
                                         DatasetSpecification spec,
                                         Map<String,String> arguments,
                                         ClassLoader classLoader)
                                  throws IOException

Description copied from interface: DatasetDefinition

Provides dataset to be used to perform data operations on the dataset instance data defined by passed DatasetSpecification and the given arguments.

Parameters:

datasetContext - context for the dataset

spec - specification of the dataset instance.

arguments - arguments for this instance of the dataset. Should not be null - provide an empty map for no arguments.

classLoader - classloader to use when executing dataset operations

Returns:

dataset to perform object operations

Throws:

IOException
