Examples with DatabaseFile org.neo4j.io.layout.DatabaseFile used on opensource projects

Example 1 with DatabaseFile

use of org.neo4j.io.layout.DatabaseFile in project neo4j by neo4j.

the class StoreMigratorFileOperation method fileOperation.

/**
 * Performs a file operation on a database's store files from one directory
 * to another. Remember that in the case of {@link FileOperation#MOVE moving files}, the way that's done is to
 * just rename files (the standard way of moving with JDK6) from and to must be on the same disk partition.
 *
 * @param fromLayout directory that hosts the database files.
 * @param toLayout directory to receive the database files.
 * @throws IOException if any of the operations fail for any reason.
