Constructor Detail

LineBreakIterator

public LineBreakIterator()

Default constructor.

LineBreakIterator

public LineBreakIterator(String text)

Creates a new line break iterator.

Parameters:

text - the text to be broken up.

Method Detail

nextPosition

public int nextPosition()

Returns the position of the next break.

Returns:

A position.

nextWithEnd

public int nextWithEnd()

Same like next(), but returns the End-Of-Text as if there was a linebreak added (Reader.readLine() compatible)

Returns:

The next position.

getText

public String getText()

Returns the text to be broken up.

Returns:

The text.

setText

public void setText(String text)

Sets the text to be broken up.

Parameters:

text - the text.

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 Iterator

Returns:

true if the iterator has more elements.

next

public Object next()

Returns the next element in the iteration.

Specified by:

next in interface 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 Iterator

Throws:

UnsupportedOperationException - if the remove operation is not supported by this Iterator.

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.
