Class SimpleLongArray.Iterator

java.lang.Object
com.tangosol.util.SimpleLongArray.Iterator
All Implemented Interfaces:
LongArray.Iterator, Iterator
Enclosing class:
SimpleLongArray
public class SimpleLongArray.Iterator extends Object implements LongArray.Iterator
An Iterator that adds a "current element" concept, similar to the Map.Entry interface.

  • Constructor Summary

    Description
    Iterator(int iNext, boolean fForward)
    Construct an iterator that will iterate over the SimpleLongArray starting with the specified index.

  • 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.
    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.
    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).
    Object
    setValue(Object oValue)
    Stores a new value at the current value index, returning the value that was replaced.

  • Constructor Details

    • Iterator

      public Iterator(int iNext, boolean fForward)
      Construct an iterator that will iterate over the SimpleLongArray starting with the specified index.
      Parameters:
      iNext - the index to start iterating from

  • Method Details

    • hasNext

      public 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
      Specified by:
      hasNext in interface LongArray.Iterator
      Returns:
      true if the iterator has more elements

    • next

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

    • getIndex

      public long getIndex()
      Returns the index of the current value, which is the value returned by the most recent call to the next method.
      Specified by:
      getIndex in interface LongArray.Iterator
      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

      public 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.
      Specified by:
      getValue in interface LongArray.Iterator
      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

      public Object setValue(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.
      Specified by:
      setValue in interface LongArray.Iterator
      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

      public 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
      Specified by:
      remove in interface LongArray.Iterator
      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.
