class	swissknife::CommandMigrate

Detailed Description

This class wraps a catalog database and provides methods to query for directory entries. It has a pointer to its parent catalog and its children, thereby creating a tree structure of nested catalogs.

Read-only catalog. A sub-class provides read-write access.

Drops the nested catalog cache. Usually this is only useful in subclasses that implement writable catalogs.

Note: this action is not secured by the catalog's mutex. If serialisation is required the subclass needs to ensure that.
