- All Implemented Interfaces:
SwingConstants
,SequenceRenderContext
public class SubSequenceRenderContext extends Object implements SequenceRenderContext
Allows a new renderer to "wrap" another one, replacing one or more values.Use this when implementing SequenceRenderer classes that modify the data that is passed on to delegate renderers e.g. filtering the features, transforming the sequence or moving the rendering co-ordinates.

Method Detail
-
getDirection
public int getDirection()
Description copied from interface:SequenceRenderContext
Gets the direction in which this context expects sequences to be rendered - HORIZONTAL or VERTICAL.- Specified by:
getDirection
in interfaceSequenceRenderContext
- Returns:
- The Direction value
-
getScale
public double getScale()
Description copied from interface:SequenceRenderContext
Gets the scale as pixels per Symbol- Specified by:
getScale
in interfaceSequenceRenderContext
- Returns:
- The scale value
-
sequenceToGraphics
public double sequenceToGraphics(int i)
Description copied from interface:SequenceRenderContext
Converts a sequence index into a graphical coordinate. You will need to use this in conjunction with getDirection to correctly lay graphics out.- Specified by:
sequenceToGraphics
in interfaceSequenceRenderContext
- Parameters:
i
- Index within the sequence- Returns:
- Equivalent graphical position in pixels
-
graphicsToSequence
public int graphicsToSequence(double d)
Description copied from interface:SequenceRenderContext
Converts a graphical position into a sequence coordinate. You will need to have used getDirection to decide whether to use the x or y coordinate.- Specified by:
graphicsToSequence
in interfaceSequenceRenderContext
- Parameters:
d
- A pixel position- Returns:
- The corresponding sequence index
-
graphicsToSequence
public int graphicsToSequence(Point2D point)
Description copied from interface:SequenceRenderContext
Converts a graphical position into a sequence coordinate. This will use getDirection to decide whether to use the x or y coordinate.- Specified by:
graphicsToSequence
in interfaceSequenceRenderContext
- Parameters:
point
- a point representing the position- Returns:
- the corresponding sequence index
-
getSymbols
public SymbolList getSymbols()
Description copied from interface:SequenceRenderContext
The SymbolList that is currently rendered by this SequenceRenderContext.- Specified by:
getSymbols
in interfaceSequenceRenderContext
- Returns:
- The Sequence value
-
getFeatures
public FeatureHolder getFeatures()
Description copied from interface:SequenceRenderContext
The features to render.- Specified by:
getFeatures
in interfaceSequenceRenderContext
- Returns:
- a FeatureHolder with the Features to render
-
getRange
public RangeLocation getRange()
Description copied from interface:SequenceRenderContext
The range of the SymbolList to render.- Specified by:
getRange
in interfaceSequenceRenderContext
- Returns:
- the RangeLocation specifying which indices (inclusive) to render
-
getLeadingBorder
public SequenceRenderContext.Border getLeadingBorder()
Description copied from interface:SequenceRenderContext
Gets the LeadingBorder attribute of the SequenceRenderContext object. This represents the space between the beginning of the rendering area and the beginning of the sequence.- Specified by:
getLeadingBorder
in interfaceSequenceRenderContext
- Returns:
- The LeadingBorder value
-
getTrailingBorder
public SequenceRenderContext.Border getTrailingBorder()
Description copied from interface:SequenceRenderContext
Gets the TrailingBorder attribute of the SequenceRenderContext object. This represents the space between the end of the sequence and the end of the rendering area.- Specified by:
getTrailingBorder
in interfaceSequenceRenderContext
- Returns:
- The TrailingBorder value
-
getFont
public Font getFont()
Description copied from interface:SequenceRenderContext
Gets the Font attribute of the SequenceRenderContext object- Specified by:
getFont
in interfaceSequenceRenderContext
- Returns:
- The Font value
