Constructor Details
-
ClassLoaderLogContextSelector
Construct a new instance. If no matching log context is found, the provided default selector is consulted.- Parameters:
defaultSelector
- the selector to consult if no matching log context is found
-
ClassLoaderLogContextSelector
public ClassLoaderLogContextSelector(LogContextSelector defaultSelector, boolean checkParentClassLoaders) Construct a new instance. If no matching log context is found, the provided default selector is consulted. If thecheckParentClassLoaders
is set totrue
this selector recursively searches the class loader parents until a match is found or anull
parent is found.- Parameters:
defaultSelector
- the selector to consult if no matching log context is foundcheckParentClassLoaders
-true
if thelog context
could not found for the class loader and theparent class loader
should be checked
-
ClassLoaderLogContextSelector
public ClassLoaderLogContextSelector()Construct a new instance. If no matching log context is found, the system context is used. -
ClassLoaderLogContextSelector
public ClassLoaderLogContextSelector(boolean checkParentClassLoaders) Construct a new instance. If no matching log context is found, the system context is used. If thecheckParentClassLoaders
is set totrue
this selector recursively searches the class loader parents until a match is found or anull
parent is found.- Parameters:
checkParentClassLoaders
-true
if thelog context
could not found for the class loader and theparent class loader
should be checked

Method Details
-
getLogContext
Get the current log context. This instance will consult the call stack to see if any calling classloader is associated with any log context.- Specified by:
getLogContext
in interfaceLogContextSelector
- Returns:
- the current log context
-
addLogApiClassLoader
Register a class loader which is a known log API, and thus should be skipped over when searching for the log context to use for the caller class.- Parameters:
apiClassLoader
- the API class loader- Returns:
true
if this class loader was previously unknown, orfalse
if it was already registered
-
removeLogApiClassLoader
Remove a class loader from the known log APIs set.- Parameters:
apiClassLoader
- the API class loader- Returns:
true
if the class loader was removed, orfalse
if it was not known to this selector
-
registerLogContext
public void registerLogContext(ClassLoader classLoader, LogContext logContext) throws IllegalArgumentException Register a class loader with a log context. This method requires theregisterLogContext
RuntimePermission
.- Parameters:
classLoader
- the classloaderlogContext
- the log context- Throws:
IllegalArgumentException
- if the classloader is already associated with a log context
-
unregisterLogContext
Unregister a class loader/log context association. This method requires theunregisterLogContext
RuntimePermission
.- Parameters:
classLoader
- the classloaderlogContext
- the log context- Returns:
true
if the association exists and was removed,false
otherwise
