Method Detail

toArray

public java.lang.Object[] toArray()
Returns an array containing all of the elements in this collection.

Specified by:
toArray in interface java.util.Collection
Specified by:
toArray in interface java.util.Set
Overrides:
toArray in class AbstractKeyBasedMap.KeySet
Returns:
an array containing all of the elements in this collection

toArray

public java.lang.Object[] toArray(java.lang.Object[] ao)
Returns an array with a runtime type is that of the specified array and that contains all of the elements in this collection. If the collection fits in the specified array, it is returned therein. Otherwise, a new array is allocated with the runtime type of the specified array and the size of this collection.

If the collection fits in the specified array with room to spare (i.e. the array has more elements than the collection), the element in the array immediately following the end of the collection is set to null. This is useful in determining the length of the collection only if the caller knows that the collection does not contain any null elements.)

Specified by:
toArray in interface java.util.Collection
Specified by:
toArray in interface java.util.Set
Overrides:
toArray in class AbstractKeyBasedMap.KeySet
Parameters:
ao - the array into which the elements of the collection are to be stored, if it is big enough; otherwise, a new array of the same runtime type is allocated for this purpose
Returns:
an array containing the elements of the collection
