<br><br>1. Get a clean 3.8 image<br>2. Load Magma1.0<br>3. Load Lava (28) and Lava testing (23) from SqueakMap<br>4. Load Magma research-brp.2.mcz.<br><br>In a workspace execute:<br> LavaTestResource current<br><br>
This creates the test Magma/Lava database.<br><br>Inspect this Lava query:<br><br> LavaTestResource current session execute: '<br> select * from people<br> where (familyName = ''Man'')
<br> or ( (familyName = ''Pinkney'') and (age <= 60) )'.<br><br><br><br>My proposed Magma client API to create a reader which can query multiple<br>indices is:<br><br>LavaTestResource current people where: [ :r |
<br> (r read: #familyName at: 'Man') |<br> ( (r read: #familyName at: 'Pinkney') & (r read: #age to: 60) )<br>].<br><br>Inspecting this returns a MagmaExpression reader with a correctly populated
<br>'expression' tree.<br><br>I think this interface is acceptably elegant and can be used to construct the<br>MaBitmapIndex for this query.<br><br>Comments welcomed<br><br>Brent<br><br><br>_______________________________________________
