> 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.
