공개 메소드들

메소드 설명
Dispose ( ) : void

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
Finalize ( Code function ) : MapReduce

Function to apply to all the results when finished.
KeepTemp ( bool keep ) : MapReduce

When true the generated collection is not treated as temporary. Specifying out automatically makes the collection permanent
Limit ( long limit ) : MapReduce

Number of objects to return from collection
Map ( Code function ) : MapReduce

The map function references the variable this to inspect the current object under consideration. A map function must call emit(key,value) at least once, but may be invoked any number of times, as may be appropriate.
Map ( string function ) : MapReduce

The map function references the variable this to inspect the current object under consideration. A map function must call emit(key,value) at least once, but may be invoked any number of times, as may be appropriate.
MapReduce ( IMongoDatabase database, string name, Type rootType ) : System

Initializes a new instance of the MapReduce class.
Out ( Document @out ) : MapReduce

Specifies how to handle the final collection of results
Out ( String name ) : MapReduce

Name of the final collection the results should be stored in.

A temporary collection is still used and then renamed to the target name atomically.

Query ( Document query ) : MapReduce

Query filter object
Reduce ( Code function ) : MapReduce

The reduce function receives a key and an array of values. To use, reduce the received values, and return a result.

The MapReduce engine may invoke reduce functions iteratively; thus, these functions must be idempotent. If you need to perform an operation only once, use a finalize function.

Reduce ( string function ) : MapReduce

The reduce function receives a key and an array of values. To use, reduce the received values, and return a result.

The MapReduce engine may invoke reduce functions iteratively; thus, these functions must be idempotent. If you need to perform an operation only once, use a finalize function.

Scope ( Document scope ) : MapReduce

Document where fields go into javascript global scope
Sort ( Document sort ) : MapReduce

Sort the query. Useful for optimization
Verbose ( bool val ) : MapReduce

Provides statistics on job execution time.
