|
* NAME

|
* ElementCollector -- constructor method
|

*
|
|
* SYNOPSIS
|
|
* ElementCollector(nSecurityId, nBufferId, nPriority, bToModify
|
|
* xReferenceResolvedListener);
|
|
*
|
|
* 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.
