Class Summary

DataUtilities Utility methods for use with some of the data classes (but not the datasets, see org.jfree.data.general.DatasetUtilities).

DefaultKeyedValue A (key, value) pair.

DefaultKeyedValues An ordered list of (key, value) items.

DefaultKeyedValues2D A data structure that stores zero, one or many values, where each value is associated with two keys (a 'row' key and a 'column' key).

DomainOrder Used to indicate sorting order if any (ascending, descending or none).

KeyedObject A (key, object) pair.

KeyedObjects A collection of (key, object) pairs.

KeyedObjects2D A data structure that stores zero, one or many objects, where each object is associated with two keys (a 'row' key and a 'column' key).

KeyedValueComparator A utility class that can compare and order two KeyedValue instances and sort them into ascending or descending order by key or by value.

KeyedValueComparatorType Used to indicate the type of a KeyedValueComparator : 'by key' or 'by value'.

KeyToGroupMap A class that maps keys (instances of Comparable) to groups.

Range Represents an immutable range of values.

RangeType Used to indicate the type of range to display on an axis (full, positive or negative).

Exception Summary

UnknownKeyException An exception that indicates an unknown key value.
