Class ZArrayNumberer<E extends Numberable>

java.lang.Object

soot.jimple.spark.geom.utils.ZArrayNumberer<E>

All Implemented Interfaces:

Iterable<E>, IterableNumberer<E>, Numberer<E>

public class ZArrayNumberer<E extends Numberable>
extends Object
implements IterableNumberer<E>, Iterable<E>

Similar to the ArrayNumberer class in soot. But, this class counts the objects from zero. And, we permit the deletion of objects from the array container. And most importantly, we permits the search for a particular object efficiently. Therefore, this class supports efficiently insert, lookup, deletion and traversal queries.

Method Detail

add

public void add(E o)

Description copied from interface: Numberer

Tells the numberer that a new object needs to be assigned a number.

Specified by:

add in interface Numberer<E extends Numberable>

clear

public void clear()

Clear the reference to the objects to help the garbage collection

get

public long get(E o)

Input object o should be added to this container previously.

Specified by:

get in interface Numberer<E extends Numberable>

get

public E get(long number)

Description copied from interface: Numberer

Should return the object that was assigned the number number.

Specified by:

get in interface Numberer<E extends Numberable>

searchFor

public E searchFor(E o)

Input object o is not required to be an object added previously.

Parameters:

o -

Returns:

remove

public boolean remove(E o)

Description copied from interface: Numberer

Removes the number for a given object.

Specified by:

remove in interface Numberer<E extends Numberable>

Parameters:

o - the element

Returns:

true if the removal was successful, false when not

size

public int size()

Return how many objects are in the container but not the capacity of the container.

Specified by:

size in interface Numberer<E extends Numberable>

reassign

public void reassign()

The removed objects cause some empty slots. We shift the objects to the empty slots in order to ensure ids of the objects are less than the filledCells.

iterator

public Iterator<E> iterator()

Description copied from interface: IterableNumberer

Returns an iterator over all objects added to the numberer.

Specified by:

iterator in interface Iterable<E extends Numberable>

Specified by:

iterator in interface IterableNumberer<E extends Numberable>
