Method Detail

iterator
public TIntIterator iterator()
Creates an iterator over the values of the set. The iterator supports element deletion.- Specified by:
iterator
in interfaceTIntCollection
- Specified by:
iterator
in interfaceTIntSet
- Returns:
- an
TIntIterator
value
-
getNoEntryValue
public int 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 interfaceTIntCollection
- Specified by:
getNoEntryValue
in interfaceTIntSet
- Returns:
- the value that represents null
-
size
public 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 interfaceTIntCollection
- Specified by:
size
in interfaceTIntSet
- Returns:
- the number of elements in this set (its cardinality)
-
isEmpty
public boolean isEmpty()
Returns true if this set contains no elements.- Specified by:
isEmpty
in interfaceTIntCollection
- Specified by:
isEmpty
in interfaceTIntSet
- Returns:
- true if this set contains no elements
-
contains
public boolean contains(int entry)
Returns true if this set contains the specified element.- Specified by:
contains
in interfaceTIntCollection
- Specified by:
contains
in interfaceTIntSet
- Parameters:
entry
- anint
value- Returns:
- true if the set contains the specified element.
-
toArray
public int[] 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 interfaceTIntCollection
- Specified by:
toArray
in interfaceTIntSet
- Returns:
- an array containing all the elements in this set
-
toArray
public int[] toArray(int[] 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
TIntSet.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 interfaceTIntCollection
- Specified by:
toArray
in interfaceTIntSet
- Parameters:
dest
- the array into which the elements of this set are to be stored.- Returns:

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