THPDFObjectLifecycleState Type

Tracks where a PDF object stands in the loaded object graph lifecycle

Declaration

THPDFObjectLifecycleState= (olsClean, olsDirty, olsReleased,
    olsMustWrite, olsRaw, olsParsed, olsFlushed);

HPDFObjs

Value	Meaning
`olsClean`	The object is stable and not scheduled to be written
`olsDirty`	The object was modified after it was last written; part of the `IsDirty` set
`olsReleased`	The object was released
`olsMustWrite`	The object is flagged so that it is always written regardless of dirty tracking; it also counts as dirty
`olsRaw`	An indexed but not yet materialised object-graph entry
`olsParsed`	An object materialised from source bytes with no modifications
`olsFlushed`	An object already serialised into the output document

The original four states keep their ordinals and the three newer states are appended, so persisted ordinals and set-based logic such as IsDirty = [olsDirty, olsMustWrite] stay valid
The THPDFObject methods MarkClean, MarkDirty, MarkReleased, MarkMustWrite, MarkRaw, MarkParsed and MarkFlushed shift objects between states
