Interface LongArray.Iterator<V>

All Superinterfaces:
Iterator<V>
All Known Implementing Classes:
AbstractSafeLongArray.SafeIterator, AbstractSparseArray.Crawler, ConverterCollections.ConverterLongArray.ConverterLongArrayIterator, CopyOnWriteLongArray.UnmodifiableIterator, PrimitiveSparseArray.Iterator, SimpleLongArray.Iterator
Enclosing interface:
LongArray<V>
public static interface LongArray.Iterator<V> extends Iterator<V>
An Iterator that adds a "current element" concept, similar to the Map.Entry interface.

  • Method Summary

    Modifier and Type
    Method
    Description
    long
    getIndex()
    Returns the index of the current value, which is the value returned by the most recent call to the next method.
    V
    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.
    V
    next()
    Returns the next element in the iteration.
    void
    remove()
    Removes from the underlying collection the last element returned by the iterator (optional operation).
    V
    setValue(V oValue)
    Stores a new value at the current value index, returning the value that was replaced.

  • Method Details

    • 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 Iterator<V>
      Returns:
      true if the iterator has more elements

    • next

      V next()
      Returns the next element in the iteration.
      Specified by:
      next in interface Iterator<V>
      Returns:
      the next element in the iteration
      Throws:
      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.
      Returns:
      the index of the current value
      Throws:
      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

      V 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:
      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

      V setValue(V 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.
      Parameters:
      oValue - the new value to store
      Returns:
      the replaced value
      Throws:
      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 Iterator<V>
      Throws:
      UnsupportedOperationException - if the remove operation is not supported by this Iterator
      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.
