Method Detail

bind

public static void bind()

Binds the current thread to its thread scope. Repeated calls to bind() will erase prior contents of the thread-scope namespace, thus it is safe to use with pooled threads.

bind

public static void bind(javax.servlet.ServletContext ctx)

bind

public static void bind(javax.servlet.http.HttpServletRequest request,
                        javax.servlet.http.HttpServletResponse response,
                        javax.servlet.http.HttpSession session,
                        javax.servlet.ServletContext ctx)

unbind

public static void unbind()

Removes the scope bindings from the calling thead. The global scope is not thead-specific, so it may be accessed even after unbind() has been called.

getScopeDictionary

public static ScopeDictionary getScopeDictionary(BeanDefinition def)
                                          throws IllegalBeanDefinitionException

getScopeDictionary

public static ScopeDictionary getScopeDictionary(CurrentContext currentContext,
                                                 BeanDefinition def)
                                          throws IllegalBeanDefinitionException

Gets the proper scope for a set of BeanAttributes.

lookupScope

public static int lookupScope(java.lang.String scope)
                       throws IllegalBeanDefinitionException
