public GPoint getControlPoint()

explode

public ArrayList<GPoint> explode()

decompose

public void decompose()

Specified by:

decompose in interface DecomposeWhenDrawn<Segment>

getDecomposeList

public ArrayList<RenderState<Segment,GObject>> getDecomposeList()

Specified by:

getDecomposeList in interface DecomposeWhenDrawn<Segment>

genericRenderStateList

public ArrayList genericRenderStateList()

Overrides:

genericRenderStateList in class GObject

onEvent

public void onEvent(EventType event,
 EventPayload properties)

Description copied from interface: EventListener

onEvent is called by EventEmitter via EventEmitter.broadcast(EventType, EventPayload). Allowing the emitter to call any other object that implements this.

Specified by:

onEvent in interface EventListener

Overrides:

onEvent in class GObject

Parameters:

event - The type of event

properties - The given event payload

getDupeObjectToCheck

public SamePair<Double> getDupeObjectToCheck()

Description copied from interface: IdempotentEventListener

Returns the duplicate object that events of type T will calculate/generate.

Specified by:

getDupeObjectToCheck in interface IdempotentEventListener<GPointMovedEvent,SamePair<Double>>

Returns:

The duplicate object to check against.

handlePossibleDuplicates

public void handlePossibleDuplicates(EventType type,
 GPointMovedEvent payload)

Description copied from interface: IdempotentEventListener

The handler to pass through for this specific type.

Specified by:

handlePossibleDuplicates in interface IdempotentEventListener<GPointMovedEvent,SamePair<Double>>

Parameters:

type - The type of event.

payload - The payload given.

copy

public void copy(CopyProperties props)
          throws InvalidCopyException

Description copied from interface: CanCopy

Copies the properties of this object based on the provided CopyProperties. The implementation should handle how the copying is performed, potentially creating a new instance or modifying an existing one.

Specified by:

copy in interface CanCopy

Overrides:

copy in class GObject

Parameters:

props - The properties defining how the copy operation should be performed.

Throws:

InvalidCopyException - If the copy operation cannot be completed due to invalid properties or state.

copy

protected GCurve copy(GPoint copyA,
 GPoint control,
 GPoint copyB)

getEngineObjectType

public EngineObject.Type getEngineObjectType()

Specified by:

getEngineObjectType in class GObject

toObject

public EngineObject toObject()

Overrides:

toObject in class GObject
