  • mapping_count(orgGridUnit, destGridUnit, value type)

definition

mapping_count(orgGridUnit, destGridUnit, value type) is defined as the count of the number of cells of the orgGridUnit domain in the destGridUnit domain, expressed in the value type argument.

description

The mapping_count(orgGridUnit, destGridUnit, uint32) function is synonym for pcount(mapping(orgGridUnit, destGridUnit)). Use the mapping_count function if the number of cells in the orgGridUnit is very large (the mapping function would than also result in a large data item). The explicit configuration of the value type is also useful to limit the size of the resulting data item.

applies to

Domain units orgGridUnit and destGridUnit with a Point value type of the group CanBeDomainUnit
