          jmri.configurexml.BlockManagerXml

All Implemented Interfaces:

XmlAdapter

public class BlockManagerXml
extends AbstractMemoryManagerConfigXML

Persistency implementation for BlockManager persistance.

The Block objects are not yet read in, pending a reliable write out!

Every block is written twice. First, the list of blocks is written without contents, so that we're sure they're all created on read-back. Then, they're written out again with contents, including the block references in the path elements.

Since:

2.1.2
