public int <B>getFlowSpan</B>(int&nbsp;index)</PRE>
<DL>
<DD>Fetch the constraining span to flow against for
 the given child index.  This is called by the
 FlowStrategy while it is updating the flow.
 A flow can be shaped by providing different values
 for the row constraints.  By default, the entire
 span inside of the insets along the flow axis
 is returned.<DD><DL>
<DT><B>Parameters:</B><DD><CODE>index</CODE> - the index of the row being updated.
   This should be a value >= 0 and < getViewCount().<DT><B>See Also: </B><DD><A HREF="../../../javax/swing/text/FlowView.html#getFlowStart(int)"><CODE>getFlowStart(int)</CODE></A></DL>

public int <B>getFlowStart</B>(int&nbsp;index)</PRE>
<DL>
<DD>Fetch the location along the flow axis that the
 flow span will start at.  This is called by the
 FlowStrategy while it is updating the flow.
 A flow can be shaped by providing different values
 for the row constraints.<DD><DL>

<PRE>
protected abstract <A HREF="../../../javax/swing/text/View.html">View</A> <B>createRow</B>()</PRE>
<DL>
<DD>Create a View that should be used to hold a 
 a rows worth of children in a flow.  This is
 called by the FlowStrategy when new children
 are added or removed (i.e. rows are added or
 removed) in the process of updating the flow.</DL>

loadChildren</H3>
<PRE>
protected void <B>loadChildren</B>(<A HREF="../../../javax/swing/text/ViewFactory.html">ViewFactory</A>&nbsp;f)</PRE>
<DL>
<DD>Loads all of the children to initialize the view.
 This is called by the <code>setParent</code> method.
 This is reimplemented to not load any children directly
 (as they are created in the process of formatting).
 If the layoutPool variable is null, an instance of
 LogicalView is created to represent the logical view
 that is used in the process of formatting.<DD><DL>

layout</H3>
<PRE>
protected void <B>layout</B>(int&nbsp;width,
                      int&nbsp;height)</PRE>
<DL>
<DD>Lays out the children.  If the span along the flow
 axis has changed, layout is marked as invalid which
 which will cause the superclass behavior to recalculate
 the layout along the box axis.  If the FlowStrategy 
 reports that a layout is needed, the FlowStrategy.layout
 method will be called to rebuild the flow rows as 
 appropriate.  If the height of this view changes 
 (determined by the perferred size along the box axis),
 a preferenceChanged is messaged.  Following all of that,
 the normal box layout of the superclass is performed.<DD><DL>
