THPDFObjectLifecycleState Type

Tracks where a PDF object sits 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 for writing
`olsDirty`	The object was modified since it was last written; part of the `IsDirty` set
`olsReleased`	The object was released
`olsMustWrite`	The object is flagged to always be written regardless of dirty tracking; also counts as dirty
`olsRaw`	An indexed but not yet materialized object-graph entry
`olsParsed`	An object materialized from source bytes without modifications
`olsFlushed`	An object already serialized to the output document

The original four states keep their ordinals and the three newer states append, 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 move objects between states
