Constructor Detail

AbstractSdmxDataReaderEngine

public AbstractSdmxDataReaderEngine(ReadableDataLocation dataLocation,
                            SdmxBeanRetrievalManager beanRetrieval,
                            DataStructureBean defaultDsd,
                            DataflowBean dataflowBean,
                            ProvisionAgreementBean provisionAgreement)

Creates a reader engine based on the data location, the location of available data structures that can be used to retrieve dsds, and the default dsd to use

Parameters:

dataLocation - the location of the data

beanRetrieval - giving the ability to retrieve dsds for the datasets this reader engine is reading. This can be null if there is only one relevent dsd - in which case the default dsd should be provided

defaultDsd - the default dsd to use if the beanRetrieval is null, or if the bean retrieval does not return the dsd for the given dataset

Method Detail

reset

public void reset()

Closes all the streams and recreates them from the input locations

Specified by:

reset in interface DataReaderEngine

Overrides:

reset in class AbstractDataReaderEngine

getHeader

public HeaderBean getHeader()

Description copied from interface: DataReaderEngine

Returns the header of the datasource that this reader engine is reading data for. The header is related to the message and not an individual dataset

Specified by:

getHeader in interface DataReaderEngine

Overrides:

getHeader in class AbstractDataReaderEngine

Returns:

close

public void close()

Description copied from interface: DataReaderEngine

Closes the reader engine, and releases all resources.
