Deprecated.

Adds a map phase to the job

Parameters:

function - function to run for the phase

keep - should the server keep and return the results

Returns:

current MapReduceBuilder instance. This is done so multiple calls to map, reduce, and link can be chained together a la StringBuffer

map

public MapReduceBuilder map(MapReduceFunction function,
                            boolean keep)

Deprecated.

Adds a map phase to the job

Parameters:

function - function to run for the phase

keep - should the server keep and return the results

Returns:

current MapReduceBuilder instance. This is done so multiple calls to map, reduce, and link can be chained together a la StringBuffer

map

                            Object arg,
                            boolean keep)

Deprecated.

Adds a map phase to the job

Parameters:

function - function to run for the phase

arg - Static argument to pass to the function. Should be an object easily converted to JSON

keep - should the server keep and return the results

Returns:

current MapReduceBuilder instance. This is done so multiple calls to map, reduce, and link can be chained together a la StringBuffer

Deprecated.

Adds a reduce phase to the job

Parameters:

function - function to run for the phase

keep - should the server keep and return the results

Returns:

current MapReduceBuilder instance. This is done so multiple calls to map, reduce, and link can be chained together a la StringBuffer

reduce

public MapReduceBuilder reduce(MapReduceFunction function,

                             boolean keep)

Deprecated.

Adds a link phase to the job

Parameters:

bucket - bucket to link walk

keep - should the server keep and return the results

Returns:

current MapReduceBuilder instance. This is done so multiple calls to map, reduce, and link can be chained together a la StringBuffer Pointing at a bucket without specifying a link tag will follow all links pointing to objects in the bucket

link

public MapReduceBuilder link(String bucket,
                             String tag,
                             boolean keep)

Adds a link phase to the job

Parameters:

bucket - bucket to link walk

tag - link tag to match

keep - should the server keep and return the results

Returns:

current MapReduceBuilder instance. This is done so multiple calls to map, reduce, and link can be chained together a la StringBuffer

submit

Deprecated.

Submits the job to the Riak server

Parameters:

meta - Extra metadata to attach to the request such as HTTP headers or query parameters.
