getOrCreate	back to summary
pack-priv JarFile getOrCreate(URL url, boolean useCaches) throws IOException Get or create a `JarFile` for the given `url`. If `useCaches` is true, this method attempts to find a jar file in the cache, and if so, returns it. If no jar file is found in the cache, or `useCaches` is false, the method creates a new jar file. If the URL points to a local file, the returned jar file will not be put in the cache yet. The caller should then call `cacheIfAbsent(URL, JarFile)` with the returned jar file, if updating the cache is desired. Parameters url:URL the jar file url useCaches:boolean whether the cache should be used Returns:JarFile a new or cached jar file. Exceptions IOException: if the jar file couldn't be created

pack-priv JarFile getOrCreate(URL url, boolean useCaches) throws IOException

If no jar file is found in the cache, or useCaches is false, the method creates a new jar file. If the URL points to a local file, the returned jar file will not be put in the cache yet. The caller should then call cacheIfAbsent(URL, JarFile) with the returned jar file, if updating the cache is desired.

Parameters

url:URL: the jar file url
useCaches:boolean: whether the cache should be used

Returns:JarFile

a new or cached jar file.
