org.apache.felix.framework.cache.BundleCache
This class, combined with BundleArchive, and concrete BundleRevision subclasses, implement the Felix bundle cache. It is possible to configure the default behavior of this class by passing properties into Felix' constructor. The configuration properties for this class are (properties starting with "felix" are specific to Felix, while those starting with "org.osgi" are standard OSGi properties):
- felix.cache.filelimit - The integer value of this string sets an upper limit on how many files the cache will open. The default value is zero, which means there is no limit.
- org.osgi.framework.storage - Sets the directory to use as the bundle cache; by default bundle cache directory is felix-cache in the current working directory. The value should be a valid directory name. The directory name can be either absolute or relative. Relative directory names are relative to the current working directory. The specified directory will be created if it does not exist.
- felix.cache.rootdir - Sets the root directory to use to calculate the bundle cache directory for relative directory names. If org.osgi.framework.storage is set to a relative name, by default it is relative to the current working directory. If this property is set, then it will be calculated as being relative to the specified root directory.
- felix.cache.locking - Enables or disables bundle cache locking, which is used to prevent concurrent access to the bundle cache. This is enabled by default, but on older/smaller JVMs file channel locking is not available; set this property to false to disable it.
- felix.cache.bufsize - Sets the buffer size to be used by the cache; the default value is 4096. The integer value of this string provides control over the size of the internal buffer of the disk cache for performance reasons.
