Method Detail

hasNext

public boolean hasNext()

Check whether a next line is available. Calling of hasNext() is usual always before next. But it is not forbidden to call next before evaluate the content. Because the returned next() is always the same instance, only with changed position, here hasNext() must not invoke thinks of the following next()!
If hasNext() is called twice without next(), it is ok.

Specified by:

hasNext in interface java.util.Iterator<StringPart>

next

public StringPart next()

Returns the next line. Here the next line is preset in the same instance of the outer class, which is returned. It uses StringPart.nextlineMaxpart().
Note: Changing the StringPart.endMax with other operations changes the spread. That is especially StringPart.setParttoMax() and StringPart.setCurrentMaxPart(). This operations should not be used in this iterator environment.
But especially all other scan Functions can be used. Especially StringPart.fromEnd() etc. can be used. The line returned here is determined with the spread from StringPart.begiMin to StringPart.endMax which are not changed by this operations.
