Interface Scheduler

All Superinterfaces:

Listener, Model, ParsedObject

All Known Implementing Classes:

BasicScheduler

public interface Scheduler
extends ParsedObject, Model, Listener

Interface for a blackboard-style scheduler. It is created by a XML configuration language and executes the dataaquisition layer first, followed by each algorithm in order. Scheudler implementations that differ from this assumption must explicitly state so in their documentation.

Method Detail

load

void load(DataAquisition loader)

set the data-aquisition component to be executed

Parameters:

loader - acquisition method.

load

void load(Algorithm algorithm,
          java.util.regex.Pattern graphIDPattern)

set an algorithm to be executed.

Parameters:

algorithm - array of algorithms to execute against the graph

set

void set(Graph g)

Set the graph that will serve as the data structure to be executed against

Parameters:

g - graph that will be the data structure

get

Graph get()

Return the graph produced and altered by the data aquisition and algorithms.

Returns:

graph associated with this scheduler

load

void load(java.io.InputStream config)
