public BackingBeanScopeProvider()

Method Detail

begin

public abstract void begin(java.lang.String scopeId)

Indicates the beginning of a new scope instance. The scope identified will remain current until end() is called.

Due to the scope ID being unique per component instance, a component will get one scope. This means that inside of a forEach loop, there will be one scope per stamp of the loop. For iteration, like af:iterator, there will be one scope, shared across each stamp.

Parameters:

scopeId - identifier for the scope, unique for the duration of the request. The ID is unique per component instance.

end

public abstract void end()

Indicates the end of the current scope as identified by the scope ID of a previous call to begin(). This also makes the previous scope (if any) current again.
