Method Detail

getWrappedSet

public java.util.Set getWrappedSet()

toString

public java.lang.String toString()
Description copied from class: java.lang.Object
Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).


hashCode

public int hashCode()
Description copied from interface: java.util.Set
Returns the hash code for this set. In order to satisfy the contract of equals, this is the sum of the hashcode of all elements in the set.

Specified by:
hashCode in interface java.util.Set

equals

public boolean equals(java.lang.Object o)
Description copied from interface: java.util.Set
Compares the specified object to this for equality. For sets, the object must be a set, the two must have the same size, and every element in one must be in the other.

Specified by:
equals in interface java.util.Set

size

public int size()
Description copied from interface: java.util.Set
Returns the number of elements in the set. If there are more than Integer.MAX_VALUE mappings, return Integer.MAX_VALUE. This is the cardinality of the set.

Specified by:
size in interface java.util.Set

isEmpty

public boolean isEmpty()
Description copied from interface: java.util.Set
Returns true if the set contains no elements.

Specified by:
isEmpty in interface java.util.Set

contains

public boolean contains(java.lang.Object arg0)
Description copied from interface: java.util.Set
Returns true if the set contains the specified element. In other words, this looks for o == null ? e == null : o.equals(e).

Specified by:
contains in interface java.util.Set

iterator

public java.util.Iterator iterator()
Description copied from interface: java.util.Set
Returns an iterator over the set. The iterator has no specific order, unless further specified.

Specified by:
iterator in interface java.util.Set

toArray

public java.lang.Object[] toArray()
Description copied from interface: java.util.Set
Returns an array containing the elements of this set. If the set makes a guarantee about iteration order, the array has the same order. The array is distinct from the set; modifying one does not affect the other.

Specified by:
toArray in interface java.util.Set

toArray

public java.lang.Object[] toArray(java.lang.Object[] arg0)
Description copied from interface: java.util.Set
Returns an array containing the elements of this set, of the same runtime type of the argument. If the given set is large enough, it is reused, and null is inserted in the first unused slot. Otherwise, reflection is used to build a new array. If the set makes a guarantee about iteration order, the array has the same order. The array is distinct from the set; modifying one does not affect the other.

Specified by:
toArray in interface java.util.Set

add

public boolean add(java.lang.Object arg0)
Description copied from interface: java.util.Set
Adds the specified element to the set if it is not already present (optional operation). In particular, the comparison algorithm is o == null ? e == null : o.equals(e). Sets need not permit all values, and may document what exceptions will be thrown if a value is not permitted.

Specified by:
add in interface java.util.Set

remove

public boolean remove(java.lang.Object arg0)
Description copied from interface: java.util.Set
Removes the specified element from this set (optional operation). If an element e exists, o == null ? e == null : o.equals(e), it is removed from the set.

Specified by:
remove in interface java.util.Set

containsAll

public boolean containsAll(java.util.Collection arg0)
Description copied from interface: java.util.Set
Returns true if this set contains all elements in the specified collection. If the argument is also a set, this is the subset relationship.

Specified by:
containsAll in interface java.util.Set

addAll

public boolean addAll(java.util.Collection arg0)
Description copied from interface: java.util.Set
Adds all of the elements of the given collection to this set (optional operation). If the argument is also a Set, this returns the mathematical union of the two. The behavior is unspecified if the set is modified while this is taking place.

Specified by:
addAll in interface java.util.Set

retainAll

public boolean retainAll(java.util.Collection arg0)
Description copied from interface: java.util.Set
Retains only the elements in this set that are also in the specified collection (optional operation). If the argument is also a set, this performs the intersection of the two sets.

Specified by:
retainAll in interface java.util.Set

removeAll

public boolean removeAll(java.util.Collection arg0)
Description copied from interface: java.util.Set
Removes from this set all elements contained in the specified collection (optional operation). If the argument is a set, this returns the asymmetric set difference of the two sets.

Specified by:
removeAll in interface java.util.Set

clear

public void clear()
Description copied from interface: java.util.Set
Removes all elements from this set (optional operation). This set will be empty afterwords, unless an exception occurs.

Specified by:
clear in interface java.util.Set
