* FUNCTION
* construct an ElementCollector object.
*
* INPUTS
* nSecurityId - represents which security entity the buffer node is
* related with. Either a signature or an encryption is
* a security entity.
* nBufferId - the id of the element bufferred in the document
* wrapper component. The document wrapper component
* uses this id to search the particular bufferred
* element.
* nPriority - the priority value. ElementCollector with lower
* priority value can't notify until all ElementCollectors
* with higher priority value have notified.
* bToModify - A flag representing whether this ElementCollector
* notification will cause the modification of its working
* element.
* xReferenceResolvedListener
* - the listener that this ElementCollector notifies to.
