Class MutableFieldAccessPoint

java.lang.Object

desmoj.extensions.experimentation.reflect.FieldAccessPoint

desmoj.extensions.experimentation.reflect.MutableFieldAccessPoint

All Implemented Interfaces:

AccessPoint, MutableAccessPoint

public class MutableFieldAccessPoint
extends FieldAccessPoint
implements MutableAccessPoint

A mutable access point using reflection to get and set a field's value. This pattern can be found in several frameworks for agent- or component-based simulation (e.g. 'Probes' in Swarm - see www.swarm.org). The term 'access point' was adopted from the dissertation "Ein flexibler, CORBA-basierter Ansatz fuer die verteilte, komponentenorientierte Simulation" by Ralf Bachmann (2003).

Constructor Detail

MutableFieldAccessPoint

public MutableFieldAccessPoint(java.lang.reflect.Field field,
                               java.lang.Object accessed)

Creates a new MutableFieldAccessPoint for the given field. The name is equal to the field name.

Parameters:

field - the field to access

accessed - the accessed object

MutableFieldAccessPoint

public MutableFieldAccessPoint(java.lang.String name,
                               java.lang.String fieldName,
                               java.lang.Object accessed)

Creates a new MutableFieldAccessPoint for the field specified by the given field name and declaring class. The access point might have a name different from the field name.

Parameters:

fieldName - the name of the field to access

name - the name of the access point

accessed: - The inspected object

MutableFieldAccessPoint

public MutableFieldAccessPoint(java.lang.String fieldName,
                               java.lang.Object accessed)

Creates a new MutableFieldAccessPoint for the field specified by the given field name and object. The access point's name is equal to the field name.

Parameters:

fieldName - the name of the field to access

accessed: - The object possesing the field

Method Detail
