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

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.

getClass()
Returns the runtime class of this Object .

hashCode()
Returns a hash code value for the object.

notify()
Wakes up a single thread that is waiting on this object's
monitor.
|
final

|
notifyAll()
Wakes up all threads that are waiting on this object's monitor.
|
String
|
toString()
Returns a string representation of the object.
|
final

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.
