Class LineRenderAttributes

java.lang.Object
  com.davisor.graphics.RenderAttributes
      com.davisor.graphics.chart.LineRenderAttributes

All Implemented Interfaces:

com.davisor.core.Dupable, java.io.Serializable

Direct Known Subclasses:

DataRenderAttributes

public class LineRenderAttributes

extends RenderAttributes

LineRenderAttributes represents attributes for chart lines. Line attributes are inherited from RenderAttributes super-class, and they control the following line rendering aspects:

• default line width and stroke
• default draw and fill colors
• default font
• default point symbol shape

The attributes cover three sets of rendering attributes, one for default point attributes, one for default line attributes, and one for value attributes. The default attribute values will be used whenever a corresponding rendering attribute is otherwise unspecified, as described in attribute reference document.

Since:

JDK1.4

Constructor Detail

LineRenderAttributes

public LineRenderAttributes()

Default constructor.

See Also:

RenderAttributes.RenderAttributes(int)

LineRenderAttributes

public LineRenderAttributes(LineRenderAttributes lra)

Shallow copy constructor.

Parameters:

lra - render attributes to be copied (may be null)

See Also:

RenderAttributes.RenderAttributes(RenderAttributes)

LineRenderAttributes

public LineRenderAttributes(LineRenderAttributes lra,
                            LineRenderAttributes defaults)

Shallow copy constructor, with explicitly given default values.

If given defaults are null, given principal render attributes defaults are used, if available. If not, default attributes remains unset. In any case, they may be later set with RenderAttributes.setDefaults(com.davisor.graphics.RenderAttributes).

If given principal render attributes source lra is null, render attributes set size is copied from given defaults, if possible. If both arguments are null, render attribute set size and defaults remain undetermined.

Parameters:

lra - render attributes to be copied (may be null)

defaults - default render attibutes (may be null)

RenderAttributes.RenderAttributes(RenderAttributes,RenderAttributes)

LineRenderAttributes

public LineRenderAttributes(java.awt.Paint color,
                            java.awt.Paint paint,
                            java.awt.Stroke stroke,
                            java.awt.Shape shape,
                            java.awt.Font font,
                            int alignment,
                            java.awt.Composite composite,
                            RenderAttributes defaults)

Creates a render attributes set with the given initial default attribute values. All rendering attributes will be installed in slot zero. The default index is also set to zero. The result is that the attribute set will behave as if it had an equal value initially set for each slot.

Minimum and maximum shape size values, if set, will define the size range to which the sizes of dynamically scaled shapes will mapped.

Parameters:

color - initial color attribute values (may be null)

paint - initial paint attribute values (may be null)

stroke - initial stroke attribute values (may be null)

shape - initial shape attribute values (may be null)

font - initial font attribute values (may be null)

alignment - initial alignment attribute values (RenderAttributes alignment code)

composite - initial composite attribute values (may be null)

defaults - default attribute values (may be null)

LineRenderAttributes

public LineRenderAttributes(java.awt.Paint[] colors,
                            java.awt.Paint[] paints,
                            java.awt.Stroke[] strokes,
                            java.awt.Shape[] shapes,
                            java.awt.Font[] fonts,
                            int[] alignments,
                            java.awt.Composite[] composites,
                            RenderAttributes defaults)

Creates a render attributes set with the given initial attribute values. A null value array will leave all attributes values as null (or UNSET).

Minimum and maximum shape size values, if set, will define the size range to which the sizes of dynamically scaled shapes will mapped.

Parameters:

colors - initial color attribute values (may be null)

paints - initial paint attribute values (may be null)

strokes - initial stroke attribute values (may be null)

shapes - initial shape attribute values (may be null)

fonts - initial font attribute values (may be null)

alignments - initial alignment attribute values (array of RenderAttributes alignment codes, may be null)

composites - initial composite attribute values (may be null)

defaults - default attribute values (may be null)
