- a Collection that will be duplicated.

Method Detail

iterator
public TFloatIterator iterator()
Creates an iterator over the values of the set. The iterator supports element deletion.- Specified by:
iterator
in interfaceTFloatCollection
- Specified by:
iterator
in interfaceTFloatSet
- Returns:
- an
TFloatIterator
value
-
toArray
public float[] 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 interfaceTFloatCollection
- Specified by:
toArray
in interfaceTFloatSet
- Returns:
- an array containing all the elements in this set
-
toArray
public float[] toArray(float[] 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
TFloatSet.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 interfaceTFloatCollection
