Direct Known Subclasses:

WrapperCollections.AbstractWrapperListIterator

Enclosing class:

WrapperCollections

public abstract static class WrapperCollections.AbstractWrapperIterator

extends java.lang.Object

implements java.util.Iterator

Iterator implementation which delegates all calls to another Iterator.

Constructor Summary

protected

WrapperCollections.AbstractWrapperIterator(java.util.Iterator iter) Create an AbstractWrapperIterator which delegates to the specified Iterator.

Method Summary

boolean	equals(java.lang.Object o)
protected java.util.Iterator	getDelegate() Return the Iterator to which all operations should be delegated to.
int	hashCode()
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.String	toString()

Constructor Detail

WrapperCollections.AbstractWrapperIterator

protected WrapperCollections.AbstractWrapperIterator(java.util.Iterator iter)

Create an AbstractWrapperIterator which delegates to the specified Iterator.

Parameters:

iter - the Iterator to delegate all calls to

Method Detail

getDelegate

protected java.util.Iterator getDelegate()

Return the Iterator to which all operations should be delegated to.

Returns:

the wrapped Iterator

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 java.util.Iterator

Returns:

true if the iterator has more elements.

next

public java.lang.Object next()

Returns the next element in the iteration. Calling this method repeatedly until the Iterator.hasNext() method returns false will return each element in the underlying collection exactly once.

Specified by:

next in interface java.util.Iterator

Returns:

the next element in the iteration.

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 java.util.Iterator

equals

public boolean equals(java.lang.Object o)

hashCode

public int hashCode()

toString

public java.lang.String toString()
