LogInputFileIterator

LogInputFileIterator(Collection files,
                     LogFile baseLogFile)

Create a new LogInputFileIterator object for the given list.

Method Detail

hasNext

public boolean hasNext()

Specified by:

hasNext in interface Iterator

next

public Object next()

Return the next File object, or null. You will get null when the file existed at the time of listing, but no longer exists when the iterator gets to it. For example, if a process is consuming all completed logs, the listing might find a log, but that process may have consumed and removed it by the time you invoke next, so you will get a null.

Specified by:

next in interface Iterator

remove

public void remove()

Remove the File object returned by the iterator from the list. This does not remove the file itself.

Specified by:

remove in interface Iterator
