Method Detail

updateDirectBuffer

public void updateDirectBuffer()
                        throws DataException,
                               java.lang.OutOfMemoryError

Interpolate source values in order to fit with collection time reference. _values _min, _max are updated.

Throws:

DataException

java.lang.OutOfMemoryError

getTimeDoubleValue

protected double getTimeDoubleValue(long index)
                             throws DataException

Compute time value for specified index.

Parameters:

index -

Returns:

corresponding time value for specified index.

Throws:

DataException

computeMax

public java.lang.Object computeMax()
                            throws UnsupportedOperation

Overrides:

computeMax in class CollectiveDataSource

Throws:

UnsupportedOperation

computeMin

public java.lang.Object computeMin()
                            throws UnsupportedOperation

Description copied from class: CollectiveDataSource

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

Overrides:

computeMin in class CollectiveDataSource

Throws:

UnsupportedOperation

getMax

public java.lang.Object getMax()
                        throws UnsupportedOperation

Overrides:

getMax in class CollectiveDataSource

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 CollectiveDataSource

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 CollectiveDataSource

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()

Description copied from class: CollectiveDataSource

These methods are common to the whole collection

Overrides:

getInformation in class CollectiveDataSource

setInfo

protected void setInfo(java.lang.String name)

getObjectValue

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

Description copied from class: ValueProvider

Naming compatibility function. Calls getValue()

Overrides:

getObjectValue 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 CollectiveDataSource

Throws:

DataException

getValue

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

Overrides:

getValue in class CollectiveDataSource

Throws:

DataException

getDoubleMax

public double getDoubleMax()
                    throws DataException

Overrides:

getDoubleMax in class CollectiveDataSource

Throws:

DataException

getDoubleMin

public double getDoubleMin()
                    throws DataException

Overrides:

getDoubleMin in class CollectiveDataSource

Throws:

DataException
