Functions to perform multi threaded reductions and analysis of arbitrary point attribute types. Each function imposes various requirements on the point ValueType (such as expected operators) and supports arbitrary point filters. More...

Detailed Description

Functions to perform multi threaded reductions and analysis of arbitrary point attribute types. Each function imposes various requirements on the point ValueType (such as expected operators) and supports arbitrary point filters.
