Method Detail

shutdown

default void shutdown(java.lang.String fqcn,
                      java.lang.ClassLoader loader,
                      boolean currentContext,
                      boolean allContexts)

Shuts down the LoggerContext.

Parameters:

fqcn - The fully qualified class name of the caller.

loader - The ClassLoader to use or null.

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

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

Since:

2.13.0

hasContext

default boolean hasContext(java.lang.String fqcn,
                           java.lang.ClassLoader loader,
                           boolean currentContext)

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

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.

Since:

2.13.0

getContext

LoggerContext getContext(java.lang.String fqcn,
                         java.lang.ClassLoader loader,
                         java.lang.Object externalContext,
                         boolean currentContext)

Creates a LoggerContext.

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.

externalContext - An external context (such as a ServletContext) to be associated with the LoggerContext.

Returns:

The LoggerContext.

getContext

LoggerContext getContext(java.lang.String fqcn,
                         java.lang.ClassLoader loader,
                         java.lang.Object externalContext,
                         boolean currentContext,
                         java.net.URI configLocation,
                         java.lang.String name)

Creates a LoggerContext.

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.

configLocation - The location of the configuration for the LoggerContext.

externalContext - An external context (such as a ServletContext) to be associated with the LoggerContext.

name - The name of the context or null.

Returns:

The LoggerContext.

removeContext

void removeContext(LoggerContext context)

Removes knowledge of a LoggerContext.

Parameters:

context - The context to remove.
