Method Detail

setTransformation

public void setTransformation(GraphTransformation transformation)

Description copied from interface: CanvasView

Sets the transformation. The said transformation is applied before rendering.

Specified by:

setTransformation in interface CanvasView

addTransformation

public void addTransformation(GraphTransformation transformation)

Description copied from interface: CanvasView

Adds a transformation to the chain of transformations. The transformations will be applied successively, in REVERSE order: Last added first.

Specified by:

addTransformation in interface CanvasView

getTransformations

public List getTransformations()

getName

public String getName()

Specified by:

getName in interface CanvasView

setName

public void setName(String name)

getType

public String getType()

setType

public void setType(String type)

getNewInstance

public CanvasView getNewInstance(GraphCanvas canvas)

Specified by:

getNewInstance in interface CanvasView

invalidate

public void invalidate()

Description copied from interface: CanvasView

Forces the view to reevaluate its internal state. This method is called whenever the structure of the graph changes

Specified by:

invalidate in interface CanvasView

getGraph

Specified by:

getGraph in interface CanvasView

setGraph

public void setGraph(GraphInterface graph)

Specified by:

setGraph in interface CanvasView

reLayout

public void reLayout()

Specified by:

reLayout in interface CanvasView

setViewport

public void setViewport(Rectangle rect)

Specified by:

setViewport in interface CanvasView

getViewport

public Rectangle getViewport()

Specified by:

getViewport in interface CanvasView

isSelective

public boolean isSelective()

Specified by:

isSelective in interface CanvasView

clean

public void clean()

Description copied from interface: CanvasView

Specified by:

activate in interface CanvasView

getRenderer

public CanvasRenderer getRenderer()

Specified by:

getRenderer in interface CanvasView

setRenderer

public void setRenderer(CanvasRenderer renderer)

Description copied from interface: CanvasView
