TimeStampedEmptyDataSource

public TimeStampedEmptyDataSource(java.lang.String dsId,
                                  java.lang.String dscId,
                                  java.lang.Object dsOptionalInformation)

                                  TimeStampedDataSourceCollection.InvalidFormatException

Throws:

java.io.IOException

TimeStampedDataSourceCollection.InvalidFormatException

Method Detail

getDataSourceId

public java.lang.String getDataSourceId()

Specified by:

getDataSourceId in interface EmptyDataSource

Returns:

data source id related to missing data source

getDataSourceCollectionId

public java.lang.String getDataSourceCollectionId()

Specified by:

getDataSourceCollectionId in interface EmptyDataSource

Returns:

data source collection id related to missing data source

getDataSourceOptionalInformation

public java.lang.Object getDataSourceOptionalInformation()

Specified by:

getDataSourceOptionalInformation in interface EmptyDataSource

Returns:

data source optional information related to missing data source

getValue

public java.lang.Object getValue(long index)
                          throws DataException

Specified by:

getValue in class TimeStampedDataSource

Throws:

DataException

getDoubleValue

public double getDoubleValue(long index)
                      throws DataException

Description copied from class: ValueProvider

Optimized accessor for double values. If the provider can provide doubles directly, then it should override this method. Otherwise, the default implementation will do its best to convert the Object returned by getValue() to a double. This conversion also parses strings, and returns 0 if it failed. An exception is thrown if, and only if, getValue throws it.

Specified by:

getDoubleValue in class TimeStampedDataSource

Throws:

DataException

isValid

public boolean isValid()

Specified by:

isValid in class TimeStampedDataSource

Returns:

true if it is valid

getEnd

public double getEnd()

Specified by:

getEnd in class TimeStampedDataSource

getStart

public double getStart()

Specified by:

getStart in class TimeStampedDataSource

getLastIndex

public long getLastIndex()
                  throws UnsupportedOperation

Specified by:

getLastIndex in class TimeStampedDataSource

Throws:

UnsupportedOperation

getStartIndex

public long getStartIndex()
                   throws UnsupportedOperation

Specified by:

getStartIndex in class TimeStampedDataSource

Throws:

UnsupportedOperation

computeMinMax

protected void computeMinMax()
                      throws UnsupportedOperation

Specified by:

computeMinMax in class TimeStampedDataSource

Throws:

UnsupportedOperation

computeMin

public java.lang.Object computeMin()
                            throws UnsupportedOperation
