Method Detail

getAllReportedDates

public java.util.Map<TIME_FORMAT,java.util.List<java.lang.String>> getAllReportedDates(DataReaderEngine dataReaderEngine)

Description copied from interface: DataInformationManager

Returns an ordered list of all the unique dates for each time format in the dataset.

This list is ordered with the earliest date first.

This method will call reset() on the dataReaderEngine before and after the information has been gathered

Specified by:

getAllReportedDates in interface DataInformationManager

Returns:

a map of time format to the list of dates that are contained for the time format

getFixedConcepts

public java.util.List<KeyValue> getFixedConcepts(DataReaderEngine dre,
                                        boolean includeObs,
                                        boolean includeAttributes)

Description copied from interface: DataInformationManager

Returns a list of dimension - value pairs where there is only a single value in the data for the dimension. For example if the entire dataset had FREQ=A then one of the returned KeyValue pairs would be FREQ,A. If FREQ=A and Q this would not be returned.

Note : an initial call to DataReaderEngine.reset will be made

Specified by:

getFixedConcepts in interface DataInformationManager

includeAttributes - if true will also report the attributes that have only one value in the entire dataset

Returns:

getDataInformation

public DataInformation getDataInformation(DataReaderEngine dre)

Description copied from interface: DataInformationManager

Returns DataInformation about the data, this processes the entire dataset to give an overview of what is in the dataset.

Specified by:

getDataInformation in interface DataInformationManager

Returns:

getDataType

public DataFormat getDataType(ReadableDataLocation sourceData)

Description copied from interface: DataInformationManager

Returns the data type for the sourceData

Specified by:

getDataType in interface DataInformationManager

Returns:

getTargetNamepace

public java.lang.String getTargetNamepace(ReadableDataLocation sourceData)

Description copied from interface: DataInformationManager

Returns the target namespace of the dataset

Specified by:

getTargetNamepace in interface DataInformationManager

Parameters:

uri -

Returns:
