Method Detail

execute

public void execute()

Description copied from interface: ISource

Execute without an incoming message

Specified by:

execute in interface ISource

add

public void add(java.lang.String name,
                DataObject<?> data)

Description copied from interface: Receptor

This method is called when the data is available

Specified by:

add in interface Receptor

Parameters:

name - name of the input

data - input data

add

public void add(java.lang.String name,
                DataPartition<?> data)

Specified by:

add in interface Receptor

getReceivableNames

public IONames getReceivableNames()

Description copied from interface: Receptor

This method should return a set of receivable names, that are expected by this receptor. 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:

getReceivableNames in interface Receptor

Returns:

get the set of names

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
