Constructor Detail

GraphProcessor

public GraphProcessor()

Creates a new instance og GraphProcessor.

Method Detail

getLogger

public Logger getLogger()

Gets the logger.

Returns:

the logger

setLogger

public void setLogger(Logger logger)

Sets a logger.

Parameters:

logger - a logger

addObserver

public void addObserver(GraphProcessingObserver processingObserver)

Adds an observer to this graph propcessor. GraphProcessingObservers are informed about processing steps of the currently running processing graph.

Parameters:

processingObserver - the observer

GraphProcessingObserver

getObservers

public GraphProcessingObserver[] getObservers()

Gets all observers currentyl attached to this GraphProcessor.

Returns:

the observers

executeGraph

public void executeGraph(Graph graph,
                         com.bc.ceres.core.ProgressMonitor pm)
                  throws GraphException

Executes the graph given by GraphContext. New graph context are created using the GraphContext#create(Graph) method.

Parameters:

graph - the Graph

pm - a progress monitor. Can be used to signal progress.

Throws:

GraphException - if any error occurs during execution

executeGraph

public Product[] executeGraph(GraphContext graphContext,
                              com.bc.ceres.core.ProgressMonitor pm)

Executes the graph given by GraphContext. New graph context are created using the GraphContext#create(Graph) method.

Parameters:

graphContext - the GraphContext to execute

pm - a progress monitor. Can be used to signal progress.

Returns:

the output products of the executed graph

executeGraphContext

@Deprecated
public void executeGraphContext(GraphContext graphContext,
                                           com.bc.ceres.core.ProgressMonitor pm)

Deprecated. since BEAM 4.9, use executeGraph(GraphContext, com.bc.ceres.core.ProgressMonitor) instead

Executes the given GraphContext.

Parameters:

graphContext - the GraphContext to execute

pm - a progress monitor. Can be used to signal progress.
