Spans

extends Object

java.lang.Object
↳	sun.java2d.Spans

Class Overview

Maintains a list of half-open intervals, called Spans. A Span can be tested against the list of Spans for intersection.

Summary

Public Constructors
	Spans()

Public Methods
void	add(float start, float end) Add a span covering the half open interval including `start` up to but not including `end`.
void	addInfinite() Add a span which covers the entire range.
boolean	intersects(float start, float end) Returns true if the span defined by the half-open interval from `start` up to, but not including, `end` intersects any of the spans defined by this instance.

Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this object.
boolean	equals(Object obj) Indicates whether some other object is "equal to" this one.
void	finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
final Class<?>	getClass() Returns the runtime class of this `Object`.
int	hashCode() Returns a hash code value for the object.
final void	notify() Wakes up a single thread that is waiting on this object's monitor.
final void	notifyAll() Wakes up all threads that are waiting on this object's monitor.
String	toString() Returns a string representation of the object.
final void	wait() Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
final void	wait(long timeout, int nanos) Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
final void	wait(long timeout) Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Public Methods

public void add (float start, float end)

Add a span covering the half open interval including start up to but not including end.

public void addInfinite ()

Add a span which covers the entire range. This call is logically equivalent to add(Float.NEGATIVE_INFINITY, Float.POSITIVE_INFINITY) The result of making this call is that all future add calls are ignored and the intersects method always returns true.

public boolean intersects (float start, float end)

Returns true if the span defined by the half-open interval from start up to, but not including, end intersects any of the spans defined by this instance.
