Method Detail

hasNext

public boolean hasNext()

Gets whether the iterator has iterated all lines available from the reader.

Specified by:

next

public java.lang.Object next()

Gets the next uniterated line available from the reader, or the last iterated line if repeat() was invoked.

Specified by:

next in interface java.util.Iterator

repeat

public void repeat()

Repeatd the last iterated line.

Throws:

java.util.NoSuchElementException - if no line has been iterated.

getLineCount

public int getLineCount()

Gets the number of the lines iterated so far. Before the first call to next(), gets 0; after the first call to next(), gets 1, and so on. Repeated lines are not multiply counted.

remove
