RegionBase | RoosterJs API Reference

Represents a DOM region. A region is a range under a given node, and possibly after one child and before another child e.g.

<div>
  <table>...</table>
  <span>...</span>
  <span>...</span>
  <table>...</table>
<div>

We can define a region under DIV before the second TABLE and after the first TABLE

This is used when user's selection go across different TD elements or start from TD and end after that TD (or inverse way). Some block operation should not ruin the TABLE structure, so we need to split the selection into several regions.
