| Standard 8 byte reference inside OnDiskGraphDB.
| xref:llvm/cas/ondisk/InternalRef4B.adoc[`InternalRef4B`] 
| Compact 4 byte reference inside OnDiskGraphDB for smaller references.
| xref:llvm/cas/ondisk/InternalRefArrayRef.adoc[`InternalRefArrayRef`] 
| Array of internal node references.
| xref:llvm/cas/ondisk/ObjectHandle.adoc[`ObjectHandle`] 
| Handle for a loaded node object.
| xref:llvm/cas/ondisk/ObjectID.adoc[`ObjectID`]
