THotPDF.ShapedRunCache Property
property ShapedRunCache: THPDFShapedRunCache;Returns the document-owned LRU cache used to reuse exact producer-side shaping runs and context-bound equal-length text slices
THPDFShapedRunKey identifies a result by stable font content when available, with pointer identity as a compatibility fallback, plus font size, an exact UInt64 feature mask, script, language, paragraph direction, vertical mode, text, and slice boundary context
TryGet performs hashed full-run lookup, while TryGetSlices can assemble a run from cached non-whitespace slices whose left and right boundary contexts match; PutSlices accepts only length-preserving results
Set MaxEntries and MaxBytes to bound memory, call Clear to invalidate all entries, and call Stats to inspect Hits, Misses, SliceHits, SliceMisses, ReusedCodeUnits, SliceEntries, Evictions, Entries, and Bytes
