DeltaTracker

public DeltaTracker(ISimulationObject object)

Method Detail

getIdentifier

public IIdentifier getIdentifier()

Specified by:

getIdentifier in interface IIdentifiable

Returns:

identifier

See Also:

IIdentifiable.getIdentifier()

get

public O get()

getDelta

public ObjectDelta getDelta()

getDelta

public ObjectDelta getDelta(boolean clearProperties)

compute the object delta for this tracker by actually iterating through the properties and comparing them to the actual object. If clearProperties is true, the changed properties will be cleared after the delta is generated. In most cases, this is what you want to do, however if you are frequently updating an object, possibly faster than common reality can reply, you will want to keep the properties (and avoid the round-trip updates).

Parameters:

clearProperties -

Returns:

hasChanged

public boolean hasChanged()

setProperty

public boolean setProperty(java.lang.String keyName,
                           java.lang.Object value)

Specified by:

setProperty in interface IMutableObject

See Also:

IMutableObject.setProperty(java.lang.String, java.lang.Object)

getProperty

public java.lang.Object getProperty(java.lang.String keyName)

Specified by:

getProperty in interface ISimulationObject

See Also:

ISimulationObject.getProperty(java.lang.String)

hasProperty

public boolean hasProperty(java.lang.String keyName)

Specified by:

hasProperty in interface ISimulationObject

See Also:

ISimulationObject.hasProperty(java.lang.String)

getProperties

public java.util.Collection<java.lang.String> getProperties()

Specified by:

getProperties in interface ISimulationObject

getPropertyMap

public java.util.Map<java.lang.String,java.lang.Object> getPropertyMap()

Specified by:

getPropertyMap in interface ISimulationObject
