Interface DomainInfo

All Known Implementing Classes:

BarXYDataset, CategoryTableXYDataset, DefaultTableXYDataset, DynamicTimeSeriesCollection, IntervalXYDelegate, TimePeriodValuesCollection, TimeSeriesCollection, TimeTableXYDataset, XYSeriesCollection

public interface DomainInfo

An interface (optional) that can be implemented by a dataset to assist in determining the minimum and maximum values. If not present, DatasetUtilities will iterate over all the values in the dataset to get the bounds.

Method Summary

Modifier and Type	Method and Description
Range	getDomainBounds(boolean includeInterval) Returns the range of the values in this dataset's domain.
double	getDomainLowerBound(boolean includeInterval) Returns the minimum x-value in the dataset.
double	getDomainUpperBound(boolean includeInterval) Returns the maximum x-value in the dataset.

Method Detail

getDomainLowerBound

double getDomainLowerBound(boolean includeInterval)

Returns the minimum x-value in the dataset.

Parameters:

includeInterval - a flag that determines whether or not the x-interval is taken into account.

Returns:

The minimum value or Double.NaN if there are no values.

getDomainUpperBound

double getDomainUpperBound(boolean includeInterval)

Returns the maximum x-value in the dataset.

Parameters:

includeInterval - a flag that determines whether or not the x-interval is taken into account.

Returns:

The maximum value or Double.NaN if there are no values.

getDomainBounds

Range getDomainBounds(boolean includeInterval)

Returns the range of the values in this dataset's domain.

Parameters:

includeInterval - a flag that determines whether or not the x-interval is taken into account.

Returns:

The range (or null if the dataset contains no values).
