void ON_Hash32TableItem::ClearHashTableSerialNumberForExperts

(

Description: Useful when copying hash tables to remove the hash table reference from a copied hash item. Never remove the hash table reference from an item that is still in a hash table.

Hash32FromId()

static ON__UINT32 ON_Hash32TableItem::Hash32FromId ( const ON_UUID &  id )

Hash32FromSHA1Hash()

static ON__UINT32 ON_Hash32TableItem::Hash32FromSHA1Hash ( const class ON_SHA1_Hash &  sha1_hash )

Returns: If this item has been added to an ON_Hash32Table.AddItem(hash32,item pointer) then the value of hash3d passed as the first argument to ON_Hash32Table.AddItem(hash32,item pointer) is returned. This is the value the ON_Hash32Table uses for this item. Othewise 0 is returned. Remarks: This function is useful when copying hash tables.
