public char[] toArray()
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.
toArray
in interface TCharSet
toArray
in interface TCharCollection
public char[] toArray(char[] dest)
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
TCharSet.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.
