...oncerned, I was just copying the code from FoldingSet. Since a lot of the keys that we're going to be dealing with are uniqued pointers, it makes sense to be able to calculate a hash of the bit-value of the pointer, rather than hashing the thing pointed to. That being said, renaming it to "addPointer" and adding a comment might be in order. Similarly, I can make the ArrayRef version 'addPointers' and have it take an ArrayRef<T*>. Now, as to the 4 bytes issue, I think I can solve that with some clever template methods. > Though it is more verbose, I think it would be b...

...the thoughts of the R-help community. I have a set of EventData, which I want to plot as points, and to color the points according to some criterion. It turns out that some of my points fall outside my desired plotting region. It looks like this causes the PBSmapping functions plotPoints and addPoints to incorrectly deal with the color assignments. Consider the following toy example: ### Begin Example ### library( PBSmapping ) # Define some EventData events <- as.EventData( read.table( textConnection( 'EID X Y Color 1 494 1494 red 2 497 1497 blue 3 500 1500 green 4 503 1503 yello...

hi all i am using geokit plugin/appln for my site..where i want to get the pointers reflected on my site by fetching the values from the db on pageload.. return (newmap.addpoint("52.802761415419674","6.6357421875","abc","abc") this is the code which is creating the ponters..I want to first of all fetch all the values from the db and get the latitude and longitude and then pass it dynamically in this addpont function.. Can any one t...

I've also tried to make the comments clear that this is intended for the case of "generic" key types, where you are either hashing multiple data types together, or you don't know in advance what the data type will be - for cases such as strings where a tailored algorithm
