Class MultiPropertiesConfig
java.lang.Object
com.mchange.v2.cfg.MultiPropertiesConfig
- Direct Known Subclasses:
- BasicMultiPropertiesConfig
public abstract class MultiPropertiesConfig
- extends Object
MultiPropertiesConfig allows applications to accept configuration data
from a more than one property file (each of which is to be loaded from
a unique path using this class' ClassLoader's resource-loading mechanism),
and permits access to property data via the resource path from which the
properties were loaded, via the prefix of the property (where hierarchical
property names are presumed to be '.'-separated), and simply by key.
In the by-key and by-prefix indices, when two definitions conflict, the
key value pairing specified in the MOST RECENT properties file shadows
earlier definitions, and files are loaded in the order of the list of
resource paths provided a constructor.
The rescource path "/" is a special case that always refers to System
properties. No actual resource will be loaded.
The class manages a special instance called "vmConfig" which is accessable
via a static method. It's resource path is list specified by a text-file,
itself a ClassLoader managed resource, which must be located at
/com/mchange/v2/cfg/vmConfigResourcePaths.txt. This file should
be one resource path per line, with blank lines ignored and lines beginning
with '#' treated as comments.
