package org.jboss.as.ejb3.remote;
A TCCLEJBClientContextSelector is backed by TCCLEJBClientContextSelectorService which returns an appropriate org.jboss.ejb.client.EJBClientContext based on the current context classloader

Author(s):
Jaikiran Pai
    private static final Logger logger = Logger.getLogger(TCCLEJBClientContextSelector.class);
    private volatile EJBClientContext defaultEJBClientContext;

    
Sets the TCCL based client context service, which will be used to query for EJB client context, and the default EJB client context which will be used when there's no EJB client context associated with the thread context classloader when getCurrent() is invoked.

Parameters:
clientContextService The TCCLEJBClientContextSelectorService
defaultEJBClientContext The default EJB client context to fallback on when the TCCLEJBClientContextSelectorService.getCurrent() returns null
    void setup(final TCCLEJBClientContextSelectorService clientContextServicefinal EJBClientContext defaultEJBClientContext) {
        this. = clientContextService;
        this. = defaultEJBClientContext;
    }

    
Cleans up any reference to a the TCCL based context service and the default EJB client context
    void destroy() {
        this. = null;
        this. = null;
    }
    @Override
    public EJBClientContext getCurrent() {
        if (this. == null) {
            return null;
        }
        final EJBClientContext ejbClientContext = this..getCurrent();
        if (ejbClientContext != null) {
            return ejbClientContext;
        }
        // explicit isDebugEnabled() check to ensure that the SecurityActions.getContextClassLoader() isn't
        // unnecessarily executed when debug logging is disabled
        if (.isDebugEnabled()) {
            .debug("Returning default EJB client context " + this. + " since no EJB client context could be found for TCCL " + SecurityActions.getContextClassLoader());
        }
        return this.;
