Method Detail
-
getNoEntryValue
short getNoEntryValue()
Returns the value that is used to represent null. The default value is generally zero, but can be changed during construction of the collection.- Specified by:
getNoEntryValue
in interfaceTShortCollection
- Returns:
- the value that represents null
-
size
int size()
Returns the number of elements in this set (its cardinality). If this set contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.- Specified by:
size
in interfaceTShortCollection
- Returns:
- the number of elements in this set (its cardinality)
-
isEmpty
boolean isEmpty()
Returns true if this set contains no elements.- Specified by:
isEmpty
in interfaceTShortCollection
- Returns:
- true if this set contains no elements
-
contains
boolean contains(short entry)
Returns true if this set contains the specified element.- Specified by:
contains
in interfaceTShortCollection
- Parameters:
entry
- anshort
value- Returns:
- true if the set contains the specified element.
-
iterator
TShortIterator iterator()
Creates an iterator over the values of the set. The iterator supports element deletion.- Specified by:
iterator
in interfaceTShortCollection
- Returns:
- an
TShortIterator
value
-
toArray
short[] toArray()
Returns an array containing all of the elements in this set. If this set makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.The returned array will be "safe" in that no references to it are maintained by this set. (In other words, this method must allocate a new array even if this set is backed by an array). The caller is thus free to modify the returned array.
This method acts as bridge between array-based and collection-based APIs.
- Specified by:
toArray
in interfaceTShortCollection
- Returns:
- an array containing all the elements in this set
-
toArray
short[] toArray(short[] dest)
Returns an array containing elements in this set.If this set fits in the specified array with room to spare (i.e., the array has more elements than this set), the element in the array immediately following the end of the set is set to
getNoEntryValue()
. (This is useful in determining the length of this set only if the caller knows that this set does not contain any elements representing null.)If the native array is smaller than the set size, the array will be filled with elements in Iterator order until it is full and exclude the remainder.
If this set makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.
- Specified by:
toArray
in interfaceTShortCollection
- Parameters:
dest
- the array into which the elements of this set are to be stored.- Returns:
- an short[] containing all the elements in this set
- Throws:
java.lang.NullPointerException
- if the specified array is null
-

removeAll
boolean removeAll(java.util.Collection<?> collection)
Removes all of the elements in collection from the set.- Specified by:
removeAll

collection
- aTShortCollection

boolean removeAll(short[] array)
Removes all of the elements in array from the set.- Specified by:
removeAll
in interfaceTShortCollection

array
- anarray

procedure
- aTShortProcedure
value- Returns:
- false if the loop over the set terminated because the procedure returned false for some value.

equals
boolean equals(java.lang.Object o)
Compares the specified object with this set for equality. Returns true if the specified object is also a set, the two sets have the same size, and every member of the specified set is contained in this set (or equivalently, every member of this set is contained in the specified set). This definition ensures that the equals method works properly across different implementations of the set interface.- Specified by:
equals

o
- object to be compared for equality with this set- Returns:
- true if the specified object is equal to this set
-

.- Specified by:
hashCode
in interfaceTShortCollection
- Overrides:
hashCode
