All Implemented Interfaces:

public class TDoubleHashSetDecorator

extends java.util.AbstractSet

implements java.util.Set, java.lang.Cloneable

Wrapper class to make a TDoubleHashSet conform to the java.util.Set API. This class simply decorates an underlying TDoubleHashSet and translates the Object-based APIs into their Trove primitive analogs.

Note that wrapping and unwrapping primitive values is extremely inefficient. If possible, users of this class should override the appropriate methods in this class and use a table of canonical values.

Constructor Detail

TDoubleHashSetDecorator

public TDoubleHashSetDecorator(TDoubleHashSet set)

Creates a wrapper that decorates the specified primitive set.

Method Detail

clone

public java.lang.Object clone()

Clones the underlying trove collection and returns the clone wrapped in a new decorator instance. This is a shallow clone except where primitives are concerned.

Returns:

a copy of the receiver

add

public boolean add(java.lang.Object value)

Inserts a value into the set.

Specified by:

add in interface java.util.Set

equals

public boolean equals(java.lang.Object other)

Compares this set with another set for equality of their stored entries.

Specified by:

equals in interface java.util.Set

Parameters:

other - an Object value

Returns:

true if the sets are identical

clear

public void clear()

Empties the set.

Specified by:

clear in interface java.util.Set

remove

public boolean remove(java.lang.Object value)

Deletes a value from the set.

Specified by:

remove in interface java.util.Set

Parameters:

value - an Object value

Returns:

true if the set was modified

iterator

public java.util.Iterator iterator()

Creates an iterator over the values of the set.

Specified by:

iterator in interface java.util.Set

Returns:

an iterator with support for removals in the underlying set

size

public int size()

Returns the number of entries in the set.

Specified by:

size in interface java.util.Set

Returns:

the set's size.

isEmpty

public boolean isEmpty()

Indicates whether set has any entries.

Specified by:

isEmpty in interface java.util.Set

Returns:

true if the set is empty

wrap

protected java.lang.Double wrap(double k)

Wraps a value

Returns:

an Object representation of the value

unwrap

protected double unwrap(java.lang.Object value)

Unwraps a value

Returns:

an unwrapped representation of the value
