Method Detail

getValue

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

Specified by:

getValue in class ValueProvider

Throws:

DataException

getDoubleValue

public abstract 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

getStartIndex

public long getStartIndex()
                   throws UnsupportedOperation

Overrides:

getStartIndex in class DataSource

Throws:

UnsupportedOperation

getLastIndex

public long getLastIndex()
                  throws UnsupportedOperation

Overrides:

getLastIndex in class DataSource

Throws:

UnsupportedOperation

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 DataSource

Throws:

UnsupportedOperation

getMax

public java.lang.Object getMax()
                        throws UnsupportedOperation

Overrides:

getMax in class DataSource

Throws:

UnsupportedOperation

sortedOrder

public int sortedOrder()

Description copied from class: DataSource

Check if the values are sorted or not. This is usefull to optimize some computations (curves drawing for instance)

Overrides:

sortedOrder in class DataSource

Returns:

0 if the values are not sorted, 1 if the values are sorted in ascending order and -1 if the values are sorted in descending order

getInformation

public DataInfo getInformation()

Overrides:

getInformation in class DataSource

isAuxiliary

public boolean isAuxiliary()

Overrides:

isAuxiliary in class DataSource

Returns:

true if the data source is an auxiliary data source
