orbiter 2c4a672fe2 bugfixes and performance hacks for tabe index
13 years ago
orbiter dad5b586a4 added a concurrent warmin-up of Table data structures. that should speed-up the start-up process but may also cause stronger CPU load at that time.

orbiter 2c595a6a47 added new methods to count the number of objects in RWIs. lots of refactoring was necessary to introduce new Rating class and to unify naming of methods

orbiter 1912d0cccc changed handling of RowSet element retrieval: until today all elements had been copied from the underlying byte[] arrays into a new Entry object that again had a copy of a portion of that byte[] in its own bye[]. There was an option to just refer to the underlying byte[] with a pointer but that was almost never used. This commit now changes an interface to the Row class where it is now necessary to tell if a copy is always required. Fortunately the copy is only needed in very rare cases. That means that this change should cause much less memory allocation; it is expected that this happens especially during search situations.

orbiter cb1f49d0f2 replaced all 'new String' with default encoding (missing) or UTF-8 encoding with a String generation method that uses a pre-defined Charset constant for UTF-8. This avoids a cache-lookup for the Charset object using String hashing of the String 'UTF-8'.
