Remarks
Property getter documentation:
Is this Bidi object set to perform the inverse Bidi algorithm?
Note: calling this method after setting the reordering mode with setReorderingMode will return true if the reordering mode was set to REORDER_INVERSE_NUMBERS_AS_L, false for all other values.

Property setter documentation:
Modify the operation of the Bidi algorithm such that it approximates an "inverse Bidi" algorithm. This method must be called before setPara().
The normal operation of the Bidi algorithm as described in the Unicode Technical Report is to take text stored in logical (keyboard, typing) order and to determine the reordering of it for visual rendering. Some legacy systems store text in visual order, and for operations with standard, Unicode-based algorithms, the text needs to be transformed to logical order. This is effectively the inverse algorithm of the described Bidi algorithm. Note that there is no standard algorithm for this "inverse Bidi" and that the current implementation provides only an approximation of "inverse Bidi".
With isInversed set to true, this method changes the behavior of some of the subsequent methods in a way that they can be used for the inverse Bidi algorithm. Specifically, runs of text with numeric characters will be treated in a special way and may need to be surrounded with LRM characters when they are written in reordered sequence.
Output runs should be retrieved using getVisualRun(). Since the actual input for "inverse Bidi" is visually ordered text and getVisualRun() gets the reordered runs, these are actually the runs of the logically ordered output.
Calling this method with argument isInverse set to true is equivalent to calling setReorderingMode with argument reorderingMode set to REORDER_INVERSE_NUMBERS_AS_L.<br> Calling this method with argument isInverse set to false is equivalent to calling setReorderingMode with argument reorderingMode set to REORDER_DEFAULT.
