Class BundleContextSelector

java.lang.Object

org.apache.logging.log4j.core.selector.ClassLoaderContextSelector

org.apache.logging.log4j.core.osgi.BundleContextSelector

All Implemented Interfaces:

ContextSelector, LoggerContextShutdownAware

public class BundleContextSelector
extends ClassLoaderContextSelector

ContextSelector for OSGi bundles. This ContextSelector works rather similarly to the ClassLoaderContextSelector, but instead of each ClassLoader having its own LoggerContext (like in a servlet container), each OSGi bundle has its own LoggerContext.

Since:

2.1

shutdown

public void shutdown(String fqcn,
 ClassLoader loader,
 boolean currentContext,
 boolean allContexts)

Description copied from interface: ContextSelector

Shuts down the LoggerContext.

Specified by:

shutdown in interface ContextSelector

Overrides:

shutdown in class ClassLoaderContextSelector

Parameters:

fqcn - The fully qualified class name of the caller.

loader - The ClassLoader to use or null.

currentContext - If true returns the current Context, if false returns the Context appropriate

allContexts - if true all LoggerContexts that can be located will be shutdown.

getLoggerContext

private LoggerContext getLoggerContext(org.osgi.framework.Bundle bundle)

removeLoggerContext

private void removeLoggerContext(LoggerContext context)

hasContext

public boolean hasContext(String fqcn,
 ClassLoader loader,
 boolean currentContext)

Description copied from interface: ContextSelector

Checks to see if a LoggerContext is installed. The default implementation returns false.

Specified by:

hasContext in interface ContextSelector

Overrides:

hasContext in class ClassLoaderContextSelector

Parameters:

fqcn - The fully qualified class name of the caller.

loader - The ClassLoader to use or null.

currentContext - If true returns the current Context, if false returns the Context appropriate for the caller if a more appropriate Context can be determined.

Returns:

true if a LoggerContext has been installed, false otherwise.

getContext

public LoggerContext getContext(String fqcn,
 ClassLoader loader,
 boolean currentContext,
 URI configLocation)

Description copied from interface: ContextSelector

Returns the LoggerContext.

Specified by:

getContext in interface ContextSelector

Overrides:

getContext in class ClassLoaderContextSelector

Parameters:

fqcn - The fully qualified class name of the caller.

loader - ClassLoader to use or null.

currentContext - If true returns the current Context, if false returns the Context appropriate for the caller if a more appropriate Context can be determined.

configLocation - The location of the configuration for the LoggerContext.

Returns:

The LoggerContext.
