Current Status

Currently this API is invoked using map to get the JavaScript library version and mapOCL to get the optimized version. This is a temporary situation as we undergo some reworking of the API.

Elemental function described below

Optional arguments passed unchanged to elemental function

Elemental Function

this An element from the ParallelArray

Optional arguments Same as the optional arguments passed to map

Result An element to be placed in the result at the same offset we found “this”

Elements are the results of applying the elemental function to the elements in the original ParallelArray plus any optional arguments.

pa.map(function(){return this;})
