java.lang.Objectgnu.trove.TIterator
gnu.trove.TPrimitiveIterator
Implements all iterator functions for the hashed object set. Subclasses may override objectAtIndex to vary the object returned by calls to next() (e.g. for values, and Map.Entry objects).
Note that iteration is fastest if you forego the calls to hasNext in favor of checking the size of the structure yourself and then call next() that many times:
Iterator i = collection.iterator(); for (int size = collection.size(); size-- > 0;) { Object o = i.next(); }
You may, of course, use the hasNext(), next() idiom too if you aren't in a performance critical spot.
Field Summary | |
protected int |
_expectedSize
the number of elements this iterator believes are in the data structure it accesses. |
protected TPrimitiveHash |
_hash
the collection on which this iterator operates. |
protected int |
_index
the index used for iteration. |
Constructor Summary | |
TPrimitiveIterator(TPrimitiveHash hash)
Creates a TPrimitiveIterator for the specified collection. |
Method Summary | |
boolean |
hasNext()
Returns true if the iterator can be advanced past its current location. |
protected void |
moveToNextIndex()
Sets the internal index so that the `next' object can be returned. |
protected int |
nextIndex()
Returns the index of the next value in the data structure or a negative value if the iterator is exhausted. |
void |
remove()
Removes the last entry returned by the iterator. |
