Method Detail

execute

public boolean execute(IMessage message)

This method add the received message from the DataObject Source into the data objects.

Specified by:

execute in interface ICompute

prepare

public void prepare(Config cfg,
                    TaskContext context)

Description copied from interface: INode

Prepare the task to be executed

Specified by:

prepare in interface INode

Overrides:

prepare in class BaseNode

Parameters:

cfg - the configuration

context - the task context, this has runtime information about the task

get

public DataPartition<java.util.HashMap<java.lang.String,VertexStatus>> get()

Description copied from interface: Collector

get the collected valued

Specified by:

get in interface Collector

Returns:

get the default output

getCollectibleNames

public IONames getCollectibleNames()

Description copied from interface: Collector

This method should return a set of collectible names, that can be collected from this collector. These names will be used by task plan builder to cross validate parallelism between two task graphs.

If Collector C of task graph TG1 collects variable "var1" and C's parallelism is n, If Receptor R of task graph TG2 is interested in receiving "var1", R's parallelism should be equal to n and, R should have the same distribution as C among the workers.

Specified by:

getCollectibleNames in interface Collector

Returns:

set of names of collectbles
