Roland Grunberg updated ERT-666:
--------------------------------
Description:
Based on discussions with Igor, various proposals were made to improve the method
reference lookup times of the JDT Indexer.
One particular suggestion, which should be possible, with least amount of friction, would
be to provide more information about the declaring type of a method in the indexer
format.
The methodRef category table currently stores :
(symbol, number of arguments) -> document numbers (classfiles)
toString/0 -> [1, 4, 5, 25]
The proposal would change this to :
(symbol, symbol's classname, classname) -> document numbers (classfiles)
toString/0/java.lang.Object -> [1, 4, 5, 25]
Doing so should reduce the number of post-processing changes needed to verify that the
declaring type of the first set of matches corresponds to the declaring type of the
selected reference.
(/) Make the patch mostly correct
(/) Basic performance test with just a JVM target platform, and lookup of
java.lang.Object.toString()
(?) Detect method references even in dead code (this is supported by existing indexer)
(?) Detect method references in comments (annotations) (this is supported by existing
indexer)
(?) More complicated performance test against the Eclipse Platform itself for
java.lang.Object.toString()
(?) A more thorough correctness test to identify any additional differences. (eg. test
every single possible method reference, not just toString() )
