Method Detail

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

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.

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

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)

Description copied from interface: ContextSelector

Returns the LoggerContext.

Specified by:

getContext in interface ContextSelector

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.

Returns:

The LoggerContext.

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

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.

locateContext

public LoggerContext locateContext(String name,
                                   String configLocation)

removeContext

public void removeContext(LoggerContext context)

Description copied from interface: ContextSelector

Remove any references to the LoggerContext.

Specified by:

removeContext in interface ContextSelector

Parameters:

context - The context to remove.

isClassLoaderDependent

public boolean isClassLoaderDependent()

Description copied from interface: ContextSelector

Determines whether or not this ContextSelector depends on the callers classloader. This method should be overridden by implementations, however a default method is provided which always returns true to preserve the old behavior.

Specified by:

isClassLoaderDependent in interface ContextSelector

Returns:

true if the class loader is required.

getLoggerContexts

public List<LoggerContext> getLoggerContexts()

Description copied from interface: ContextSelector

Returns a List of all the available LoggerContexts.

Specified by:

getLoggerContexts in interface ContextSelector

Returns:

The List of LoggerContexts.
