public interface DataInformationManager

The purpose of the data information manager is to get metadata off the dataset.

Method Summary

Methods

Modifier and Type	Method and Description
java.util.Map<TIME_FORMAT,java.util.List<java.lang.String>>	getAllReportedDates(DataReaderEngine dataReaderEngine) Returns an ordered list of all the unique dates for each time format in the dataset.
DataInformation	getDataInformation(DataReaderEngine dre) Returns DataInformation about the data, this processes the entire dataset to give an overview of what is in the dataset.
DataFormat	getDataType(ReadableDataLocation sourceData) Returns the data type for the sourceData
java.util.List<KeyValue>	getFixedConcepts(DataReaderEngine dre, boolean includeObs, boolean includeAttributes) Returns a list of dimension - value pairs where there is only a single value in the data for the dimension.
java.lang.String	getTargetNamepace(ReadableDataLocation sourceData) Returns the target namespace of the dataset

Method Detail

getDataType

DataFormat getDataType(ReadableDataLocation sourceData)
                       throws ParseException

Returns the data type for the sourceData

Parameters:

sourceData -

Returns:

Throws:

ParseException - when the type of data can not be determined

getTargetNamepace

java.lang.String getTargetNamepace(ReadableDataLocation sourceData)

Returns the target namespace of the dataset

Parameters:

sourceData -

Returns:

getDataInformation

DataInformation getDataInformation(DataReaderEngine dre)

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

Returns:

getAllReportedDates

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

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

Returns:

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

getFixedConcepts

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

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

Parameters:

dre -

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

Returns:
