Class DefaultValueSegment<T extends Comparable,V extends Comparable>

java.lang.Object
  ca.odell.glazedlists.jfreechart.DefaultValueSegment<T,V>

All Implemented Interfaces:

ValueSegment<T,V>, Comparable<ValueSegment<T,V>>

public class DefaultValueSegment<T extends Comparable,V extends Comparable>
extends Object
implements ValueSegment<T,V>

The default implementation of the ValueSegment interface.

Note: DefaultValueSegments must be immutable objects. Callers are strongly encouraged to construct DefaultValueSegments with defensive copies of the start, end, and value arguments if they are not themselves immutable.

Constructor Summary

DefaultValueSegment(T start, T end, V value)
Create a DefaultValueSegment indicating the value exists between the start and end on some continuum of Comparable objects.

Method Summary

int	compareTo(ValueSegment<T,V> o) DefaultValueSegments are compared by value, then by segment start, then by segment end.
T	getEnd() Returns the value marking the end of this segment.
T	getStart() Returns the value marking the start of this segment.
V	getValue() Returns the value observed within this segment.
String	toString()

Constructor Detail

DefaultValueSegment

public DefaultValueSegment(T start,
                           T end,
                           V value)

Create a DefaultValueSegment indicating the value exists between the start and end on some continuum of Comparable objects.

Parameters:

start - the beginning of the segment

end - the end of the segment

value - the value observed between start and end

Throws:

IllegalArgumentException - if start or end is null

Method Detail

getStart

public T getStart()

Returns the value marking the start of this segment.

Specified by:

getStart in interface ValueSegment<T extends Comparable,V extends Comparable>

getEnd

public T getEnd()

Returns the value marking the end of this segment.

Specified by:

getEnd in interface ValueSegment<T extends Comparable,V extends Comparable>

getValue

public V getValue()

Returns the value observed within this segment.

Specified by:

getValue in interface ValueSegment<T extends Comparable,V extends Comparable>

compareTo

public int compareTo(ValueSegment<T,V> o)

DefaultValueSegments are compared by value, then by segment start, then by segment end.

Specified by:

compareTo in interface Comparable<ValueSegment<T extends Comparable,V extends Comparable>>

toString

public String toString()

Overrides:

toString in class Object
