Read Strategies

[Chris Muller]

No, it's only additive to the #minimumDepth.  I had to look at the server method where it checks the depth while reading an object graph to see if a negative depth could be specified.  Check out the method:

  MaObjectBuffer>>
    appendGraphUsing: aMaReadStrategy 
    into: aMaSerializedGraphBuffer 
    currentDepth: currentDepth
    minDepth: minDepth 
    with: alreadyAppendedSet 
    filer: aMaObjectFiler

  I agree it seems like that could be useful to subtract, but unfortunately it doesn't do that..

Chris,

is it possible to set the read strategy subtractively. I.e to a deep
level with the exception of  one attribute.

(MaReadStrategy new)
       forAny: Page readToDepth: 4;
       forVariableNamed: 'uselessStuff' readToDepth: 0.

many thanks in advance

Keith
