ReadWriteBackingMap.ValuesCollection

protected ReadWriteBackingMap.ValuesCollection()
Method Detail

iterator

public java.util.Iterator iterator()
Obtain an iterator over the values in the Map.

Specified by:
iterator in interface java.lang.Iterable
Specified by:
iterator in interface java.util.Collection
Specified by:
iterator in class java.util.AbstractCollection
Returns:
an Iterator that provides a live view of the values in the underlying Map object

size

public int size()
Determine the number of values in the Collection.

Specified by:
size in interface java.util.Collection
Specified by:
size in class java.util.AbstractCollection
Returns:
the number of values in the Collection, which is the same as the number of entries in the underlying Map

clear

public void clear()
Removes all of the elements from this Collection of values by clearing the underlying Map.

Specified by:
clear in interface java.util.Collection
Overrides:
clear in class java.util.AbstractCollection

toArray

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

Specified by:
toArray in interface java.util.Collection
Overrides:
toArray in class java.util.AbstractCollection
Returns:
an array containing all of the keys 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 keys 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
Overrides:
toArray in class java.util.AbstractCollection
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
Throws:
java.lang.ArrayStoreException - if the runtime type of the specified array is not a supertype of the runtime type of every element in this Collection of values
