Method Detail

getValue

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

Specified by:

getValue in class TimeStampedDataSource.TimeSource

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.TimeSource

Throws:

DataException

getMin

public java.lang.Object getMin()
                        throws UnsupportedOperation

Description copied from class: DataSource

Return values if possibly only, without expensive computations.

Overrides:

getMin in class TimeStampedDataSource.TimeSource

Throws:

UnsupportedOperation

getMax

public java.lang.Object getMax()
                        throws UnsupportedOperation

Overrides:

getMax in class TimeStampedDataSource.TimeSource

Throws:

UnsupportedOperation
