If view's container is a JComponent it is returned, after casting.

  Provides a way to determine the next visually represented model location that one might place a caret.

  Provides a way to determine the next visually represented model location that one might place a caret. Some views may not be visible, they might not be in the same order found in the model, or they just might not allow access to some of the locations in the model.

This implementation assumes the views are layed out in a logical manner. That is, that the view at index x + 1 is visually after the View at index x, and that the View at index x - 1 is visually before the View at x. There is support for reversing this behavior only if the passed in View is an instance of CompositeView. The CompositeView must then override the flipEastAndWestAtEnds method.
Returns: the location within the model that best represents the next location visual position
Parameters:
- v - View to query
- pos - the position to convert >= 0
- a - the allocated region to render into
- direction - the direction from the current position that can be thought of as the arrow keys typically found on a keyboard; this may be one of the following:

• SwingConstants.WEST
• SwingConstants.EAST
• SwingConstants.NORTH
• SwingConstants.SOUTH

- biasRet - an array contain the bias that was checked
Throws:
- BadLocationException -
- IllegalArgumentException - if direction is invalid
