Enum Renderer

java.lang.Object
  java.lang.Enum<Renderer>
      org.askalon.graph.chart.Renderer

All Implemented Interfaces:

Serializable, Comparable<Renderer>

public enum Renderer
extends Enum<Renderer>

This enum should be used to create renderer-specific ChartFactories.

Enum Constant Summary

HARD
The hard renderer uses hardware rendering based on Java3D to display the charts.

SOFT
The sofware renderer uses an own rendering engine based on Java2D.

Method Summary

ChartFactory	getFactory() Call this to get an instance of a renderer specific ChartFactory.
boolean	isChartAvailable(ChartType chart) Determines the availability of a chart-type for this renderer.
abstract boolean	isChartAvailable(Class<? extends Chart> c) Determines the availability of a chart-type for this renderer.
abstract boolean	isFunctional() Determines the availability of a renderer-type.
static Renderer	valueOf(String name) Returns the enum constant of this type with the specified name.
static Renderer[]	values() Returns an array containing the constants of this enum type, in the order they're declared.

Enum Constant Detail

HARD

public static final Renderer HARD

The hard renderer uses hardware rendering based on Java3D to display the charts.

SOFT

public static final Renderer SOFT

The sofware renderer uses an own rendering engine based on Java2D.

Method Detail

values

public static final Renderer[] values()

Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:

for(Renderer c : Renderer.values())
        System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they're declared

valueOf

public static Renderer valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

isFunctional

public abstract boolean isFunctional()

Determines the availability of a renderer-type.

Returns:

true if the renderer works and is ready to use, false if this renderer type is not available

isChartAvailable

public abstract boolean isChartAvailable(Class<? extends Chart> c)

Determines the availability of a chart-type for this renderer.

Parameters:

c - the class of the chart to check

Returns:

true if the chart is available for this renderer, false otherwise

See Also:

isChartAvailable(ChartType)

isChartAvailable

public boolean isChartAvailable(ChartType chart)

Determines the availability of a chart-type for this renderer.

Parameters:

chart - the type of the chart for which the availability should be checked

Returns:

true if the chart is available for this renderer, false otherwise

See Also:

ChartType, isChartAvailable(Class)

getFactory

public ChartFactory getFactory()

Call this to get an instance of a renderer specific ChartFactory. This will usually be the same all the time, for all charts used by the application.

Returns:

an instance of a ChartFactory
