Class LimitedSizeSet<T>

java.lang.Object

plume.LimitedSizeSet<T>

Type Parameters:

T - the type of elements in the set

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable

Deprecated.

use org.plumelib.util.LimitedSizeSet

@Deprecated
public class LimitedSizeSet<T>
extends java.lang.Object
implements java.io.Serializable, java.lang.Cloneable

LimitedSizeSet stores up to some maximum number of unique values. If more than that many elements are added, then functionality is degraded: most operations return a conservative estimate (because the internal representation is nulled, in order to save space).

Field Detail

values

protected T[] values

Deprecated.

If null, then at least num_values distinct values have been seen. The size is not separately stored, because that would take extra space.

Constructor Detail

LimitedSizeSet

public LimitedSizeSet(int max_values)

Deprecated.

Create a new LimitedSizeSet that can hold max_values values.

Parameters:

max_values - the maximum number of values this set will be able to hold; must be positive

Method Detail

add

public void add(T elt)

Deprecated.

addAll

public void addAll(LimitedSizeSet<? extends T> s)

Deprecated.

contains

public boolean contains(T elt)

Deprecated.

size

public int size()

Deprecated.

A lower bound on the number of elements in the set. Returns either the number of elements that have been inserted in the set, or max_size(), whichever is less.

Returns:

a number that is a lower bound on the number of elements added to the set

max_size

public int max_size()

Deprecated.

An upper bound on how many distinct elements can be individually represented in the set. Returns max_values+1 (where max_values is the argument to the constructor).

Returns:

maximum capacity of the set representation

repNulled

public boolean repNulled()

Deprecated.

Returns true if more elements have been added than this set can contain (which is the integer that was passed to the constructor when creating this set).

Returns:

true if this set has been filled to capacity and its internal representation is nulled

clone

public LimitedSizeSet<T> clone()

Deprecated.

Overrides:

clone in class java.lang.Object

merge

public static <T> LimitedSizeSet<T> merge(int max_values,
                                          java.util.List<LimitedSizeSet<? extends T>> slist)

Deprecated.

Merges a list of LimitedSizeSet<T> objects into a single object that represents the values seen by the entire list. Returns the new object, whose max_values is the given integer.

Type Parameters:

T - (super)type of elements of the sets

Parameters:

max_values - the maximum size for the returned LimitedSizeSet

slist - a list of LimitedSizeSet, whose elements will be merged

Returns:

a LimitedSizeSet that merges the elements of slist

toString

public java.lang.String toString()

Deprecated.

Overrides:

toString in class java.lang.Object
