Class RepeatIndexHandler

java.lang.Object
  fi.hut.tml.xsmiles.mlfc.xforms.ui.RepeatIndexHandler

public class RepeatIndexHandler

extends java.lang.Object

The repeat index handler. Only one instance of this class exists per document in the bubbling phase, all index values are set, and traversed indexes are unshown in the UI when the event comes to the root repeat, it starts to show nested repeat indexes if some nested repeat is outside the event target, then the nested repeat's index is set to 1 * FUNCTIONAL: o Repeat element listens for DOMFocusIn o When DOMFocusIn is received, repeat calls RepeatIndexHandler, which + unsets the previous cursors in event flow + sets the new cursors for the whole repeat hierarchy

                                   RepeatHandler handler)

the repeat has caught the DOMFocusIn event

repeatChanged

public void repeatChanged(RepeatHandler handler)

call this method when new items have been inserted into repeat or old ones removed. Set index in the model before calling this!

repeatAboutToChange

public void repeatAboutToChange(RepeatHandler handler)

call this before any changes to UI, it will clear out the previous cursor

repeatInitialized

public void repeatInitialized(RepeatHandler handler)

call this method when a repeat has been initialized in the beginning. it will show the initial cursor

setRepeatIndex

public void setRepeatIndex(org.w3c.dom.Node target,
                           RepeatHandler handler,
                           int item)

setRepeatIndexRecursively

public void setRepeatIndexRecursively(org.w3c.dom.Element elem)

getRepeatItem

public RepeatItemPseudoElement getRepeatItem(RepeatHandler handler,
                                             int i)

hasAncestorRepeat

protected boolean hasAncestorRepeat(RepeatHandler handler)

goes towards the root and reports if any repeat's are found as ancestors

resolveItemNumber

protected int resolveItemNumber(org.w3c.dom.Node target,
                                RepeatHandler handler)

find out which item was focused

resolveRepeatId

protected java.lang.String resolveRepeatId(RepeatHandler handler)

find out the repeat id of this repeat handler

unsetPreviousIndex

protected void unsetPreviousIndex(RepeatHandler handler)

unset the previous cursors for all repeats in the document, leave prevCursor=-1 if you want to use the cursor value from model

setIndexValue

protected void setIndexValue(java.lang.String repeatId,
                             int item)

set the cursor value thru model

getIndex

protected int getIndex(org.w3c.dom.Node target,
                       RepeatHandler handler)

This method handles the event when the user selects a control in repeat Events are used to set the repeatcursor to whatever the user has selected

findRepeatedId

public org.w3c.dom.Element findRepeatedId(org.w3c.dom.Element elem,
                                          java.lang.String id)

Find the active instance of the given id as determined by enclosing repeat's indexes. This is called outside this class

Parameters:

elem - the element to search for

id - the elemnt's id

Returns:

the appropriate instance; if there are no enclosing repeat's then this is just elem
