IteratorChain

public IteratorChain()

IteratorChain

public IteratorChain(java.util.Iterator[] iteratorArray)

Construct an IteratorChain with a single Iterator.

参数:

iteratorArray - iterator Array will be used in the IteratorChain

抛出:

java.lang.NullPointerException - if the iterator is null

方法详细资料

size

public int size()

Number of Iterators in the current IteratorChain.

返回:

Iterator count

hasNext

public boolean hasNext()

Return true if any Iterator in the IteratorChain has a remaining element.

指定者:

hasNext 在接口中 java.util.Iterator

返回:

true if elements remain

next

public java.lang.Object next()

Returns the next Object of the current Iterator

指定者:

next 在接口中 java.util.Iterator

返回:

Object from the current Iterator

抛出:

java.util.NoSuchElementException - if all the Iterators are exhausted

remove

public void remove()

Removes from the underlying collection the last element returned by the Iterator. As with next() and hasNext(), this method calls remove() on the underlying Iterator. Therefore, this method may throw an UnsupportedOperationException if the underlying Iterator does not support this method.

指定者:

remove 在接口中 java.util.Iterator

抛出:

java.lang.UnsupportedOperationException - if the remove operator is not supported by the underlying 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.
