All Implemented Interfaces:

java.io.Serializable, Component, Algorithm, Model

public class AggregateOnActor
extends ModelShell
implements Algorithm

Class for Aggregating the properties of an actor into a single Instance object. Each property is transformed and then aggregated. Aggregation is first performed over the values of each property, then against all properties of each actor. This aggregation is repeated across all actors of a given mode.

Create a new algorithm utilizing default parameters.

Method Detail

execute

public void execute(Graph g)

Description copied from interface: Algorithm

execute the algorithm against the given graph

Specified by:

execute in interface Algorithm

Parameters:

g - graph to be modified

getInputType

public InputDescriptor[] getInputType()

Description copied from interface: Component

The input type describes all the different kinds of graph objects that are utilized (and hence required) by this object. This result is only guaranteed to be fixed if structural parameters are not modified. This is an empty array if there is no input.

Specified by:

getInputType in interface Component

Returns:

InputDescriptor array for this component

See Also:

InputDescriptor

getOutputType

public OutputDescriptor[] getOutputType()

Description copied from interface: Component

The output type describes all the different kinds of graph objects that are created during the execution of this algorithm. The result is only guaranteed to be fixed if structural parameters are not modified. This is an empty array if there is no output.

Specified by:

getOutputType in interface Component

Returns:

OutputDescriptor array for this component

See Also:

OutputDescriptor

getParameter

public Parameter[] getParameter()

Description copied from interface: Component

List of all parameters this component accepts. Each parameter also has a distinct key-name used when initializing the object using the init method. If there are no parameters, null is returned.

Specified by:

getParameter in interface Component

Returns:

read-only array of Parameters

getParameter

public Parameter getParameter(java.lang.String param)

Description copied from interface: Component

Returns the specific parameter identified by its key-name. If no parameter is found with this key-name, null is returned.

Specified by:

getParameter in interface Component

Parameters:

param - key-name of the parameter

Returns:

named parameter

getSettableParameter

public SettableParameter[] getSettableParameter()

Description copied from interface: Component

Returns settable (i.e. editable while running) parameters. If none exist, null is returned.

Specified by:

getSettableParameter in interface Component

Returns:

array of settable parameters

getSettableParameter

public SettableParameter getSettableParameter(java.lang.String param)

Description copied from interface: Component

Return the settable parameter namede by this key-name. If this parameter is not found or is not settable, null is returned.

Specified by:

getSettableParameter in interface Component

Parameters:

param - key-name of the parameter

Returns:

named settable parameter

init

public void init(java.util.Properties map)

Parameters:

• name: Name of the algorithm. Default is 'Aggregate On Actor'
• actorType: Mode of the actor to compare. Default is 'tag'
• innerAggregator: function for aggregating the values of properties on an actor. Default is 'nz.ac.waikato.mcennis.rat.graph.algorithm.reusablecores.aggregator.FirstItemAggregatorFunction'.
• outerAggregator: function for aggregating across properties of an actor. Default is 'nz.ac.waikato.mcennis.rat.graph.algorithm.reusablecores.aggregator.ConcatenationAggregator'
• actorProperty: Name of the property on each actor to store results into. Default is 'Actor Instance'.

Specified by:

init in interface Component

Parameters:

map - parameters to be loaded - may be null
