default boolean chunkError(MinecraftCoords coords,
                           java.lang.String message)

This is called when a chunk is skipped due to a loading error, to give the visitor the opportunity to record the error or abort the process. When this is called visitChunk(Chunk) is not called for that chunk!

The default implementation just returns true so that the process continues.

Parameters:

coords - The coordinates of the problematic chunk, or null if they are not known or do not apply.

message - A message describing the problem with the chunk

Returns:

true if more chunks should be visited, or false if no more chunks should be visited.
