Class BumpedRenderer

Method Details

• getLeadingPixles

  public int getLeadingPixles()

• setLeadingPixles

  public void setLeadingPixles(int leading)

• getTrailingPixles

  public int getTrailingPixles()

• setTrailingPixles

  public void setTrailingPixles(int trailing)

• hasListeners

  protected boolean hasListeners()

  Description copied from class: AbstractChangeable

  Discover if we have any listeners registered.

  Overrides:

  hasListeners in class AbstractChangeable

  Returns:

  true if there is at least one listener

• getChangeSupport

  protected ChangeSupport getChangeSupport(ChangeType ct)

  Description copied from class: AbstractChangeable

  Called to retrieve the ChangeSupport for this object.

  Your implementation of this method should have the following structure:

   ChangeSupport cs = super.getChangeSupport(ct);
  
   if(someForwarder == null && ct.isMatching(SomeInterface.SomeChangeType)) {
     someForwarder = new ChangeForwarder(...
  
     this.stateVariable.addChangeListener(someForwarder, VariableInterface.AChange);
   }
  
   return cs;
   

  It is usual for the forwarding listeners (someForwarder in this example) to be transient and lazily instantiated. Be sure to register & unregister the forwarder in the code that does the ChangeEvent handling in setter methods.

  Overrides:

  getChangeSupport in class SequenceRendererWrapper

• getDepth

  public double getDepth(SequenceRenderContext src)

  Description copied from interface: SequenceRenderer

  Retrieve the depth of this renderer when rendering src.

  The depth may vary between sequence panels - for example based upon sequence length. Each line of information in the SequenceRendererContext only renders a region of the sequence. The depth for one complete line may be different from that for another due to the sequence having more or less information in that region to show. For example, a feature renderer implementation may chose to collapse down to a depth of zero pixels if there are no features to render within a region.

  Specified by:

  getDepth in interface SequenceRenderer

  Overrides:

  getDepth in class SequenceRendererWrapper

  Parameters:

  src - the SequenceRenderContext to return info for

  Returns:

  the depth of the renderer for that sequence panel

• getMinimumLeader

  public double getMinimumLeader(SequenceRenderContext src)

  Description copied from interface: SequenceRenderer

  Retrieve the minimum leading distance for this renderer when rendering src.

  The leading distance may vary between sequence panels - for example based upon sequence length.

  Specified by:

  getMinimumLeader in interface SequenceRenderer

  Overrides:

  getMinimumLeader in class SequenceRendererWrapper

  Parameters:

  src - the SequenceRenderContext to return info for

  Returns:

  the leading distance of the renderer for that sequence panel

• getMinimumTrailer

  public double getMinimumTrailer(SequenceRenderContext src)

  Description copied from interface: SequenceRenderer

  Retrieve the minimum trailing distance for this renderer when rendering src.

  The trailing distance may vary between sequence panels - for example based upon sequence length.

  Specified by:

  getMinimumTrailer in interface SequenceRenderer

  Overrides:

  getMinimumTrailer in class SequenceRendererWrapper

  Parameters:

  src - the SequenceRenderContext to return info for

  Returns:

  the trailing distance of the renderer for that sequence panel

• paint

  public void paint(Graphics2D g, SequenceRenderContext src)

  Description copied from interface: SequenceRenderer

  Render a portion (possibly all) of the information for src to g, displaying all of the data that would fall within seqBox.

  Specified by:

  paint in interface SequenceRenderer

  Overrides:

  paint in class SequenceRendererWrapper

  Parameters:

  g - the Graphics2D to render to

  src - the SequenceRenderContext that encapsulates the information to render

• processMouseEvent

  public SequenceViewerEvent processMouseEvent(SequenceRenderContext src, MouseEvent me, List path)

  Description copied from interface: SequenceRenderer

  Produce a SequenceViewerEvent in response to a mouse gesture.

  A SequenceRenderer that performs any form of coordinate remapping should ensure that it appropriately transforms the mouse event. However, in the SequenceViewerEvent returned, the MouseEvent should be in untransformed coordinates.

  The SequenceRenderer implementation should append itself to the path list before constructing the SequenceViewerEvent.

  Specified by:

  processMouseEvent in interface SequenceRenderer

  Overrides:

  processMouseEvent in class SequenceRendererWrapper

  Parameters:

  src - the SequenceRenderContext currently in scope

  me - a MouseEvent that caused this request

  path - the List of SequenceRenderer instances passed through so far

  Returns:

  a SequenceViewerEvent encapsulating the mouse gesture

• layer

  protected List layer(SequenceRenderContext src)

• doLayer

  protected List doLayer(SequenceRenderContext src, FeatureFilter filt)
