PageStateList (flow-engine JavaDoc)

Class PageStateList

public class PageStateList extends Object

The ReportState list stores a report states for the beginning of every page. The list is filled on repagination and read when a report or a page of the report is printed.

Important: This list stores page start report states, not arbitary report states. These ReportStates are special: they can be reproduced by calling processPage on the report.

Internally this list is organized as a list of WeakReferenceLists, where every WeakReferenceList stores a certain number of page states. The first 20 states are stored in an ordinary list with strong-references, so these states never get GarbageCollected (and so they must never be restored by reprocessing them). The next 100 states are stored in 4-element ReferenceLists, so if a reference is lost, only 4 states have to be reprocessed. All other states are stored in 10-element lists.
