public class TDoubleHashSetDecorator
extends java.util.AbstractSet<java.lang.Double>
implements java.util.Set<java.lang.Double>

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.

Field Detail

_set

protected TDoubleHashSet _set

the wrapped primitive set

Constructor Detail

TDoubleHashSetDecorator

public TDoubleHashSetDecorator(TDoubleHashSet set)

Creates a wrapper that decorates the specified primitive set.

Method Detail

getSet

public TDoubleHashSet getSet()

Returns a reference to the set wrapped by this decorator.

clone

public TDoubleHashSetDecorator 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.

Overrides:

clone in class java.lang.Object

Returns:

a copy of the receiver

add

public boolean add(java.lang.Double value)

Inserts a value into the set.

Specified by:

add in interface java.util.Collection<java.lang.Double>

Specified by:

add in interface java.util.Set<java.lang.Double>

Overrides:

add in class java.util.AbstractCollection<java.lang.Double>

Parameters:

value - true if the set was modified by the insertion

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.Collection<java.lang.Double>

Specified by:

equals in interface java.util.Set<java.lang.Double>

Overrides:

equals in class java.util.AbstractSet<java.lang.Double>

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.Collection<java.lang.Double>

Specified by:

clear in interface java.util.Set<java.lang.Double>

Overrides:

clear in class java.util.AbstractCollection<java.lang.Double>

remove

public boolean remove(java.lang.Object value)

Deletes a value from the set.

Specified by:

remove in interface java.util.Collection<java.lang.Double>

Specified by:

remove in interface java.util.Set<java.lang.Double>

Overrides:

remove in class java.util.AbstractCollection<java.lang.Double>

Parameters:

value - an Object value

Returns:

true if the set was modified

iterator

public java.util.Iterator<java.lang.Double> iterator()

Creates an iterator over the values of the set.

Specified by:

iterator in interface java.lang.Iterable<java.lang.Double>

Specified by:

iterator in interface java.util.Collection<java.lang.Double>

Specified by:

iterator in interface java.util.Set<java.lang.Double>

Specified by:

iterator in class java.util.AbstractCollection<java.lang.Double>

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.Collection<java.lang.Double>

Specified by:

size in interface java.util.Set<java.lang.Double>

Specified by:

size in class java.util.AbstractCollection<java.lang.Double>

Returns:

the set's size.

isEmpty

public boolean isEmpty()

Indicates whether set has any entries.

Specified by:

isEmpty in interface java.util.Collection<java.lang.Double>

Specified by:

isEmpty in interface java.util.Set<java.lang.Double>

Overrides:

isEmpty in class java.util.AbstractCollection<java.lang.Double>

Returns:

true if the set is empty

wrap

protected java.lang.Double wrap(double k)

Wraps a value

Parameters:

k - value in the underlying set

Returns:

an Object representation of the value

unwrap

protected double unwrap(java.lang.Object value)

Unwraps a value

Parameters:

value - wrapped value

Returns:

an unwrapped representation of the value
