Class DefaultValueSegment<T extends java.lang.Comparable,V extends java.lang.Comparable>

java.lang.Object

ca.odell.glazedlists.jfreechart.DefaultValueSegment<T,V>

All Implemented Interfaces:

ValueSegment<T,V>, java.lang.Comparable<ValueSegment<T,V>>

public class DefaultValueSegment<T extends java.lang.Comparable,V extends java.lang.Comparable>
extends java.lang.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 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:

java.lang.IllegalArgumentException - if start or end is null

Specified by:

getEnd in interface ValueSegment<T extends java.lang.Comparable,V extends java.lang.Comparable>

getValue

public V getValue()

Returns the value observed within this segment.

Specified by:

getValue in interface ValueSegment<T extends java.lang.Comparable,V extends java.lang.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 java.lang.Comparable<ValueSegment<T extends java.lang.Comparable,V extends java.lang.Comparable>>

toString

public java.lang.String toString()

Overrides:
