de.gsi.dataset.spi.AbstractStylable<D>

de.gsi.dataset.spi.AbstractDataSet<D>

de.gsi.dataset.spi.AbstractErrorDataSet<D>

Type Parameters:

D - java generics handling of DataSet for derived classes (needed for fluent design)

All Implemented Interfaces:

DataSet, DataSetError, DataSetMetaData, EventSource

Direct Known Subclasses:

AbstractTestFunction, CircularDoubleErrorDataSet, DoubleErrorDataSet, FifoDoubleErrorDataSet, LimitedIndexedTreeDataSet, ListErrorDataSet

public abstract class AbstractErrorDataSet<D extends AbstractErrorDataSet<D>>
extends AbstractDataSet<D>
implements DataSetError

The abstract implementation of DataSet and DataSetError interface that provides implementation of some methods.

• It maintains the name of the DataSet
• It maintains a list of DataSetListener objects and provides methods that can be used to dispatch DataSetEvent events.
• It maintains ranges of X and Y values including error bars
• It gives a possibility to specify an undefined value.

Constructor Detail

AbstractErrorDataSet

protected AbstractErrorDataSet(java.lang.String name)

Creates a new instance of AbstractDataSet.

Parameters:

name - of the DataSet

Throws:

java.lang.IllegalArgumentException - if name is null

Method Detail

getThis

protected D getThis()

Overrides:

getThis in class AbstractDataSet<D extends AbstractErrorDataSet<D>>

lock

public D lock()

Description copied from interface: DataSet

Locks access to the data set. Multi-threaded applications should lock the data set before setting the data.

Specified by:

lock in interface DataSet

Overrides:

lock in class AbstractDataSet<D extends AbstractErrorDataSet<D>>

Returns:

itself (fluent interface)

unlock

public D unlock()

Description copied from interface: DataSet

Unlock the data set.

Specified by:

unlock in interface DataSet

Overrides:

unlock in class AbstractDataSet<D extends AbstractErrorDataSet<D>>

Returns:

itself (fluent interface)

fireInvalidated

public D fireInvalidated(UpdateEvent event)

Description copied from class: AbstractDataSet

Notifies listeners that the data has been invalidated. If the data is added to the chart, it triggers repaint.

Overrides:

fireInvalidated in class AbstractDataSet<D extends AbstractErrorDataSet<D>>

Parameters:

event - the change event

Returns:

itself (fluent design)

getErrorType

public DataSetError.ErrorType getErrorType()

return the DataSetError.ErrorType of the dataset

Specified by:

getErrorType in interface DataSetError

Returns:

one of the error types specified in ErrorType

See Also:

for details

setErrorType

public D setErrorType(DataSetError.ErrorType errorType)

sets the error type of the data set

Parameters:

errorType - error type to be set

Returns:

itself (fluent design)

See Also:

for details

computeLimits

protected D computeLimits()

Computes limits (ranges) of this DataSet including data point errors.

Overrides:

computeLimits in class AbstractDataSet<D extends AbstractErrorDataSet<D>>

Returns:

itself (fluent design)
