The FileConfig library provide a service for accessing application-specific directories.

A lot of the Polygene™ Libraries and Extensions make use of this library to locate files.

include::../../build/docs/buildinfo/artifact.txt[]

== Usage ==

[snippet,java]
----
source=libraries/fileconfig/src/main/java/org/apache/polygene/library/fileconfig/FileConfiguration.java
tag=fileconfig
----

To use it you simply need to use the FileConfigurationAssembler in your application assembly:

[snippet,java]
----
source=libraries/fileconfig/src/test/java/org/apache/polygene/library/fileconfig/FileConfigurationTest.java
tag=simple
----

These will default to the platform settings, but can be overridden manually, either one-by-one or as a whole.

You can override defaults by adding org.apache.polygene.library.fileconfig.FileConfiguration_OS.properties files to your
classpath where OS is one of win, mac or unix.

You can also override all properties definitions at assembly time by setting a FileConfigurationOverride object
as meta info of this service:

[snippet,java]
----
source=libraries/fileconfig/src/test/java/org/apache/polygene/library/fileconfig/FileConfigurationTest.java
tag=override
----


And finally, to get the FileConfiguration Service in your application code, simply use the following:

[source,java]
----
@Service FileConfiguration fileconfig;
----
