Class Poco::OSP::OSPSubsystem

Library: OSP
Package: Util
Header: Poco/OSP/OSPSubsystem.h

Description

This subsystem implementation sets up the OSP runtime environment, including BundleLoader, CodeCache and ServiceRegistry.

It also defines the "clean" command line option, which forces the code cache to be cleared, and the "bundles" command line option which allows for specification of additional bundle repositories.

The following configuration properties are used:

osp.bundleRepository: list of directories containing bundles (defaults to ${application.dir}bundles)
osp.codeCache: location of code cache directory (defaults to ${application.dir}codeCache)
osp.language: language used for localization (overrides the system default)
osp.data the directory where temporary and persistent data for bundles is stored (defaults to ${application.dir}data)

The following configuration properties are set:

osp.version: OSP Version from osp.core bundle (only if osp.core bundle is present)
osp.osname: name of operating system
osp.osarch: hardware architecture identifier
