Method Detail

getInformation

public DataInfo getInformation()

Overrides:

getInformation in class DataSource

fillValues

protected void fillValues()

nextRandomValue

protected abstract double nextRandomValue()

For subclasses to implement according to their distribution

getValue

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

Specified by:

getValue in class ValueProvider

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.

Overrides:

getDoubleValue in class ValueProvider

Throws:

DataException

computeLastIndex

public long computeLastIndex()
                      throws UnsupportedOperation

Overrides:

computeLastIndex in class DataSource

Throws:

UnsupportedOperation

computeStartIndex

public long computeStartIndex()
                       throws UnsupportedOperation

Overrides:

computeStartIndex in class DataSource

Throws:

UnsupportedOperation

getLastIndex

public long getLastIndex()
                  throws UnsupportedOperation

Overrides:

getLastIndex in class DataSource

Throws:

UnsupportedOperation

getStartIndex

public long getStartIndex()
                   throws UnsupportedOperation

Overrides:

getStartIndex in class DataSource

Throws:

UnsupportedOperation

computeMax

public java.lang.Object computeMax()

Overrides:

computeMax in class DataSource

computeMin

public java.lang.Object computeMin()

Description copied from class: DataSource

Force the computation if possible. The operation may take some time.

Overrides:

computeMin in class DataSource

getDoubleMax

public double getDoubleMax()

Overrides:

getDoubleMax in class DataSource

getDoubleMin

public double getDoubleMin()

Overrides:

getDoubleMin in class DataSource

getMax

public java.lang.Object getMax()

Overrides:

getMax in class DataSource

getMin

public java.lang.Object getMin()

Description copied from class: DataSource

Return values if possibly only, without expensive computations.

Overrides:

getMin in class DataSource

getMaxIndex

public long getMaxIndex()

Returns:

Returns the maxIndex.
