## com.tangosol.util
Interface LongArray.Iterator

All Superinterfaces:
  java.util.Iterator

All Known Implementing Classes:
  AbstractSparseArray.Crawler, 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.
