java.rmi.server.RemoteObject

org.youscope.common.measurement.SimpleMeasurementContext

All Implemented Interfaces:

java.io.Serializable, java.rmi.Remote, MeasurementContext

public class SimpleMeasurementContext
extends java.rmi.server.UnicastRemoteObject
implements MeasurementContext

A simple implementation of a measurement context. This implementation can be used to initialize and call measurement components without the need to construct an actual measurement, e.g. during a configuration of a component to show the expected outcome given the current configuration. Note, that YouScope uses a different implementation during the execution of a measurement.

Method Detail

setProperty

public void setProperty(java.lang.String identifier,
                        java.io.Serializable property)

Description copied from interface: MeasurementContext

Sets a property, such that it can be loaded by any other job in the measurement. Any property with the same identifier will be replaced.

Specified by:

setProperty in interface MeasurementContext

Parameters:

identifier - a short identifier for the property.

property - The property which should be saved.

getPropertyIdentifiers

public java.lang.String[] getPropertyIdentifiers()

Description copied from interface: MeasurementContext

Returns the identifiers of all stored properties.

Specified by:

getPropertyIdentifiers in interface MeasurementContext

Returns:

identifiers of stored properties.

getProperty

public java.io.Serializable getProperty(java.lang.String identifier)

Description copied from interface: MeasurementContext

Returns a previously-by this or another measurement component-stored property.

Specified by:

getProperty in interface MeasurementContext

Parameters:

identifier - identifier of the property.

Returns:

previously stored property, or null if yet not stored.

getProperty

public <T extends java.io.Serializable> T getProperty(java.lang.String identifier,
                                                      java.lang.Class<T> propertyType)

Description copied from interface: MeasurementContext

Returns a previously-by this or another measurement component-stored property. The property is tried to be casted to the provided class or interface. If this fails, null is returned.

Specified by:

getProperty in interface MeasurementContext

Parameters:

identifier - identifier of the property.

propertyType - type to which the property should be casted.

Returns:

previously stored property, or null if yet not stored or cast fails.

notifyMeasurementStructureChanged

public void notifyMeasurementStructureChanged()
                                       throws java.rmi.RemoteException

Description copied from interface: MeasurementContext

Should be called if the structure of the measurement changed during execution, e.g. when child jobs were added or removed or similar.

Specified by:

notifyMeasurementStructureChanged in interface MeasurementContext

Throws:

java.rmi.RemoteException

getMeasurementUUID

public java.util.UUID getMeasurementUUID()
                                  throws java.rmi.RemoteException

Description copied from interface: MeasurementContext

Returns the unique identifier of the measurement containing this component.

Specified by:

getMeasurementUUID in interface MeasurementContext

Returns:

Unique identifier of measurement.

Throws:

java.rmi.RemoteException
