Syntax

public RiakMapReduceQuery MapErlang(
	Action<RiakFluentActionPhaseErlang> setup
)

member MapErlang : 
        setup : Action<RiakFluentActionPhaseErlang> -> RiakMapReduceQuery

setup: Type: SystemActionRiakFluentActionPhaseErlang
An ActionT that accepts a RiakFluentActionPhaseJavascript, and configures the map phase with it.

Type: RiakMapReduceQuery
A reference to this updated instance, for fluent chaining.

Remarks

Configure the phase with a lambda similar to:

.MapErlang(m => m.ModFun("riak_kv_mapreduce", "map_object_value"))

The above code will run the "riak_kv_mapreduce:map_object_value" Erlang function on each input in the phase..
