Constructor Detail

RangeSource

public RangeSource(java.lang.String name,
                   double minValue,
                   double maxValue,
                   double step)

Method Detail

getKind

public int getKind()

Description copied from class: ValueProvider

The kind of this provider may be used fo optimization purpose. This is just an indication for getXXXValue typed functions.

Overrides:

getKind in class ValueProvider

Returns:

the kind of this provider

getInformation

public DataInfo getInformation()

Overrides:

getInformation in class DataSource

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

getLongValue

public long getLongValue(long index)
                  throws DataException

Description copied from class: ValueProvider

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

Overrides:

getLongValue 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:

Overrides:

getLongMin 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

getStep

public java.lang.Number getStep()

isComparable

public boolean isComparable()

Description copied from class: DataSource

Check if the values are comparable with each other. If they are, the sortedOrder() function tells if they are also sorted.

Overrides:

isComparable in class DataSource

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

valueClass

public java.lang.Class valueClass()

Description copied from class: ValueProvider

Returns the more specialized superclass of all objects returned by this provider. Returns Object by default in the base implementation, subclass should specialize if possible.

Overrides:

valueClass in class ValueProvider
