Constructor Detail

SinusSource

public SinusSource(double freq,
                   double phase,
                   double amplitude,
                   double ofst,
                   long start,
                   long end)

Method Detail

getInformation

public DataInfo getInformation()

Overrides:

getInformation in class DataSource

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

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

computeMin

public java.lang.Object computeMin()
                            throws UnsupportedOperation

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

Overrides:

computeMin in class DataSource

Throws:

UnsupportedOperation

computeMax

public java.lang.Object computeMax()
                            throws UnsupportedOperation

Overrides:

computeMax in class DataSource

Throws:

UnsupportedOperation

public long computeStartIndex()
                       throws UnsupportedOperation

Overrides:

computeStartIndex in class DataSource

Throws:

UnsupportedOperation

computeLastIndex

public long computeLastIndex()
                      throws UnsupportedOperation

Overrides:

Throws:

UnsupportedOperation

setSlice

public void setSlice(long min,
                     long max)

Description copied from class: DataSource

Sets a region of interest in the DataSource. This is a purely informative function, but the DataSource may use this information to optimize itself on this specific range.

Overrides:

setSlice in class DataSource

getDoubleValue

public double getDoubleValue(long index)

Optimize for double access getValue calls this function and wraps a Double around

Overrides:

getDoubleValue in class ValueProvider

getValue

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

Specified by:

getValue in class ValueProvider

Throws:

DataException

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

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

update

public void update()
            throws UnsupportedOperation

Throws:

UnsupportedOperation
