Class THashPrimitiveIterator

java.lang.Object

gnu.trove.impl.hash.THashPrimitiveIterator

All Implemented Interfaces:

TIterator, TPrimitiveIterator

public abstract class THashPrimitiveIterator
extends java.lang.Object
implements 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.

Constructor Detail

THashPrimitiveIterator

public THashPrimitiveIterator(TPrimitiveHash hash)

Creates a TPrimitiveIterator for the specified collection.

Parameters:

hash - the TPrimitiveHash we want to iterate over.

Method Detail

hasNext

public boolean hasNext()

Returns true if the iterator can be advanced past its current location.

Specified by:

hasNext in interface TIterator

Specified by:

hasNext in interface TPrimitiveIterator

Returns:

a boolean value

remove

public void remove()

Removes the last entry returned by the iterator. Invoking this method more than once for a single entry will leave the underlying data structure in a confused state.
