All Implemented Interfaces:
Extent, InputExtent, OutputExtent, AutoCloseable
public class EditSession extends PassthroughExtent implements AutoCloseable
An Extent that handles history, BlockBags, change limits, block re-ordering, and much more. Most operations in WorldEdit use this class.

Most of the actual functionality is implemented with a number of other Extents that are chained together. For example, history is logged using the ChangeSetExtent.

      Description copied from interface: OutputExtent
      Change the block at the given location to the given block. The operation may not tie the given BlockStateHolder to the world, so future changes to the BlockStateHolder do not affect the world until this method is called again.

      The return value of this method indicates whether the change was probably successful. It may not be successful if, for example, the location is out of the bounds of the extent. It may be unsuccessful if the block passed is the same as the one in the world. However, the return value is only an estimation and it may be incorrect, but it could be used to count, for example, the approximate number of changes.
