Class AttrIterator


public class AttrIterator
extends Boxed

The AttrIterator object is used to represent an iterator through a List. A new iterator is created with pango_attr_list_get_iterator(). Once the iterator is created, it can be advanced through the style changes in the text using pango_attr_iterator_next(). At each style change, the range of the current style segment and the attributes currently in effect can be queried. todo: is this needed?

public AttrIterator(Handle handle)


AttrIterator

public AttrIterator(AttrIterator iter)
Create a copy of the provided iterator.

Parameters:
iter -

Method Details

finalize

protected void finalize()
            throws Throwable


get

public Attribute get(AttrType type)
Find the current attribute of a particular type at the iterator location. When multiple attributes of the same type overlap, the attribute whose range starts closest to the current location is used.


getRangeEnd

public int getRangeEnd()
Return the end of the current segment range.


getRangeStart

public int getRangeStart()
Return the beginning of the current segment range.


next

public boolean next()
Advance the iterator until the next change of style.

Returns:
false if the iterator is at the end of the list.
