Interface LongArray.Iterator

All Superinterfaces:
java.util.Iterator
All Known Implementing Classes:
AbstractSparseArray.Crawler, CopyOnWriteLongArray.UnmodifiableIterator, PrimitiveSparseArray.Iterator, SimpleLongArray.Iterator
Enclosing interface:
LongArray

public static interface LongArray.Iterator
extends java.util.Iterator

An Iterator that adds a "current element" concept, similar to the Map.Entry interface.


Method Summary
 long getIndex()
          Returns the index of the current value, which is the value returned by the most recent call to the next method.
 java.lang.Object getValue()
          Returns the current value, which is the same value returned by the most recent call to the next method, or the most recent value passed to setValue if setValue were called after the next method.
 boolean hasNext()
          Returns true if the iteration has more elements.
 java.lang.Object next()
          Returns the next element in the iteration.
 void remove()
          Removes from the underlying collection the last element returned by the iterator (optional operation).
 java.lang.Object setValue(java.lang.Object oValue)
          Stores a new value at the current value index, returning the value that was replaced.

 

Method Detail

hasNext

boolean hasNext()
Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)
Specified by:
hasNext in interface java.util.Iterator
Returns:
true if the iterator has more elements

next

java.lang.Object next()
Returns the next element in the iteration.
Specified by:
next in interface java.util.Iterator
Returns:
the next element in the iteration
Throws:
java.util.NoSuchElementException - iteration has no more elements

getIndex

long getIndex()
Returns the index of the current value, which is the value returned by the most recent call to the next method.
Throws:
java.lang.IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.

getValue

java.lang.Object getValue()
Returns the current value, which is the same value returned by the most recent call to the next method, or the most recent value passed to setValue if setValue were called after the next method.
Returns:
the current value
Throws:
java.lang.IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.

setValue

java.lang.Object setValue(java.lang.Object oValue)
Stores a new value at the current value index, returning the value that was replaced. The index of the current value is obtainable by calling the getIndex method.
Returns:
the replaced value
Throws:
java.lang.IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.

remove

void remove()
Removes from the underlying collection the last element returned by the iterator (optional operation). This method can be called only once per call to next. The behavior of an iterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method.
Specified by:
remove in interface java.util.Iterator
Throws:
java.lang.UnsupportedOperationException - if the remove operation is not supported by this Iterator
java.lang.IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.
