Jan Steemann 35f2bdb9fd fixed 2015-09-28 13:31:53 +02:00
Jan Steemann f2cbaa38e0 fixed condition printing 2015-09-25 16:35:18 +02:00
Jan Steemann abc87b2d5f added IndexNode stub 2015-09-25 13:40:51 +02:00
Michael Hackstein 2ab13b81a4 The Condition will now successfully produce a list of Indexes that can be combined for the current EnumerateCollectionBlock. If this list is empty we can do nothing but a Full Collection Scan 2015-09-25 13:00:37 +02:00
Michael Hackstein 6eb23f14f4 The Condition findIndexes now tries to find an index for each AND block and fills a list of indexes, iff there is any element in the list we are able to use a CombinedIndexRangeNode, if not we still have to use the EnumerateCollectionNode 2015-09-25 11:45:31 +02:00
Michael Hackstein 6a11ad28ee Adapted all indices to the new planned interface so they tell us if they can serve for a condition and present their costs 2015-09-25 10:40:04 +02:00
Michael Hackstein 6525755cc0 Fixed memleak 2015-09-23 17:04:37 +02:00
Michael Hackstein eae6394f22 Allowed the hashIndex to modify the DNF and-block node. It now successfully removes all entries it can be responsible for 2015-09-23 16:29:15 +02:00
Michael Hackstein aefc0edae0 Added a modifyable AST node to the index can serve and block functionality of all indicies. However non of them uses it yet 2015-09-23 14:38:23 +02:00
Michael Hackstein e6e795e198 Improved dev output. Now it is easier to see where more than one index is suiteable 2015-09-22 16:14:10 +02:00
Michael Hackstein 73077a17fc Implemented the foundation to identify indicies based on DNF Conditions. Primary is implemented as an example. Right now it is only printed that it can be used. TODO: actually use it. Other indicies 2015-09-22 15:39:07 +02:00
Michael Hackstein f1b0afd9a6 Started to implement functions to find indexes for each Condition sub part 2015-09-22 11:19:52 +02:00
