| CachedJarsPackageManager | | abstract public class CachedJarsPackageManager extends PackageManager (Code) | | Abstract package manager that gathers info about statically known classes
from a set of jars. This info can be eventually cached. Off-the-shelf this
class offers a local file-system based cache impl.

| Inner Class :public static class JarXEntry extends Object | |
| Method Summary | |
| public void | addJarToPackages(java.net.URL jarurl)
Gathers classes info from jar specified by jarurl URL. | | public void | addJarToPackages(URL jarurl, boolean cache)
Gathers classes info from jar specified by jarurl URL. | | public void | addJarToPackages(File jarfile)
Gathers classes info from jar specified by File jarfile. | | public void | addJarToPackages(File jarfile, boolean cache)
Gathers classes info from jar specified by File jarfile. | | protected void | comment(String msg)
Comment log method - hook. | | protected void | debug(String msg)
Debug log method - hook. | | protected void | deleteCacheFile(String cachefile)
Delete (invalidated) cache file from persistent storage - hook. | | protected boolean | filterByAccess(String name, int acc)
Filter class by access perms helper method - hook. | | protected boolean | filterByName(String name, boolean pkg)
Filter class/pkg by name helper method - hook. | | protected DataInputStream | inOpenCacheFile(String cachefile)
Open cache file for reading from persistent storage - hook. | | protected DataInputStream | inOpenIndex()
Open cache index for reading from persistent storage - hook. | | protected void | initCache()
Initializes cache. | | protected void | message(String msg)
Message log method - hook. | | protected DataOutputStream | outCreateCacheFile(JarXEntry entry, boolean create)
Create/open cache file for rewriting back to persistent storage - hook.
If create is false, cache file is supposed to exist and must be opened
for rewriting, entry.cachefile is a valid cachefile id. | | protected DataOutputStream | outOpenIndex()
Open cache index for writing back to persistent storage - hook. | | public void | saveCache()
Write back cache index. | | protected boolean | useCacheDir(File aCachedir1)
Initialize off-the-shelf (default) local file-system cache impl. | | protected void | warning(String warn)
Warning log method - hook. |
| addJarToPackages | | public void addJarToPackages(java.net.URL jarurl)(Code) | | Gathers classes info from jar specified by jarurl URL. Eventually just
using previously cached info. Eventually updated info is not cached.
Persistent cache storage access goes through inOpenCacheFile() and
outCreateCacheFile().
|
| addJarToPackages | | public void addJarToPackages(URL jarurl, boolean cache)(Code) | | Gathers classes info from jar specified by jarurl URL. Eventually just
using previously cached info. Eventually updated info is (re-)cached if
param cache is true. Persistent cache storage access goes through
inOpenCacheFile() and outCreateCacheFile().
|
| addJarToPackages | | public void addJarToPackages(File jarfile)(Code) | | Gathers classes info from jar specified by File jarfile. Eventually just
using previously cached info. Eventually updated info is not cached.
Persistent cache storage access goes through inOpenCacheFile() and
outCreateCacheFile().
|
| addJarToPackages | | public void addJarToPackages(File jarfile, boolean cache)(Code) | | Gathers classes info from jar specified by File jarfile. Eventually just
using previously cached info. Eventually updated info is (re-)cached if
param cache is true. Persistent cache storage access goes through
inOpenCacheFile() and outCreateCacheFile().
|
| comment | | protected void comment(String msg)(Code) | | Comment log method - hook. This default impl does nothing.
Parameters:
msg - message text |
| debug | | protected void debug(String msg)(Code) | | Debug log method - hook. This default impl does nothing.
Parameters:
msg - message text |
| deleteCacheFile | | protected void deleteCacheFile(String cachefile)(Code) | | Delete (invalidated) cache file from persistent storage - hook. This
default impl is part of the off-the-shelf local file-system cache impl.
Can be overriden.
|
| filterByName | | protected boolean filterByName(String name, boolean pkg)(Code) | | Filter class/pkg by name helper method - hook. The default impl. is used
by
CachedJarsPackageManager.addJarToPackages in order to filter out classes whose name
contains '$' (e.g. inner classes,...). Should be used or overriden by
derived classes too. Also to be used in
CachedJarsPackageManager.doDir .
Parameters:
name - class/pkg name
Parameters:
pkg - if true, name refers to a pkg true if name must be filtered out |
| inOpenCacheFile | | protected DataInputStream inOpenCacheFile(String cachefile) throws IOException(Code) | | Open cache file for reading from persistent storage - hook. This default
impl is part of the off-the-shelf local file-system cache impl. Can be
overriden.
|
| inOpenIndex | | protected DataInputStream inOpenIndex() throws IOException(Code) | | Open cache index for reading from persistent storage - hook. Must Return
null if this is absent. This default impl is part of the off-the-shelf
local file-system cache impl. Can be overriden.
|
| initCache | | protected void initCache()(Code) | | Initializes cache. Eventually reads back cache index. Index persistent
storage is accessed through inOpenIndex().
|
| message | | protected void message(String msg)(Code) | | Message log method - hook. This default impl does nothing.
Parameters:
msg - message text |
| outCreateCacheFile | | protected DataOutputStream outCreateCacheFile(JarXEntry entry, boolean create) throws IOException(Code) | | Create/open cache file for rewriting back to persistent storage - hook.
If create is false, cache file is supposed to exist and must be opened
for rewriting, entry.cachefile is a valid cachefile id. If create is
true, cache file must be created. entry.cachefile is a flat jarname to be
used to produce a valid cachefile id (to be put back in entry.cachefile
on exit). This default impl is part of the off-the-shelf local
file-system cache impl. Can be overriden.
|
| outOpenIndex | | protected DataOutputStream outOpenIndex() throws IOException(Code) | | Open cache index for writing back to persistent storage - hook. This
default impl is part of the off-the-shelf local file-system cache impl.
Can be overriden.
|
| saveCache | | public void saveCache()(Code) | | Write back cache index. Index persistent storage is accessed through
outOpenIndex().
|
| useCacheDir | | protected boolean useCacheDir(File aCachedir1)(Code) | | Initialize off-the-shelf (default) local file-system cache impl. Must be
called before
CachedJarsPackageManager.initCache . cachedir is the cache repository
directory, this is eventually created. Returns true if dir works.
|
| warning | | protected void warning(String warn)(Code) | | Warning log method - hook. This default impl does nothing.
Parameters:
warn - warning text |
