public class DisplayAll
extends ModelShell
implements Algorithm

Class that displays an entire graph inside a Prefuse display window. Each relation is assigned a color. Each actor is assigned a color. Properties are accessed via a side panel, where relation name and ID are displayed.

Method Detail

execute

public void execute(Graph g)

Description copied from interface: Algorithm

execute the algorithm against the given graph

Specified by:

execute in interface Algorithm

Parameters:

g - graph to be modified

getInputType

public java.util.List<IODescriptor> getInputType()

Description copied from interface: Component

The input type describes all the different kinds of graph objects that are utilized (and hence required) by this object. This result is only guaranteed to be fixed if structural parameters are not modified. This is an empty array if there is no input.

Specified by:

getInputType in interface Component

Returns:

IODescriptor array for this component

See Also:

IODescriptor

getOutputType

public java.util.List<IODescriptor> getOutputType()

Description copied from interface: Component

The output type describes all the different kinds of graph objects that are created during the execution of this algorithm. The result is only guaranteed to be fixed if structural parameters are not modified. This is an empty array if there is no output.

Specified by:

getOutputType in interface Component

Returns:

IODescriptor array for this component

See Also:

IODescriptor

getParameter

public Properties getParameter()

Description copied from interface: Component

List of all parameters this component accepts. Each parameter also has a distinct key-name used when initializing the object using the init method. If there are no parameters, null is returned.

Specified by:

getParameter in interface Component

Returns:

read-only array of Parameters

getParameter

public Parameter getParameter(java.lang.String param)

Description copied from interface: Component

Returns the specific parameter identified by its key-name. If no parameter is found with this key-name, null is returned.

Specified by:

getParameter in interface Component

Parameters:

param - key-name of the parameter

Returns:

named parameter

init

public void init(Properties map)

Initializes the algorithm. Only accepts the name of the algorithm as a property. 'name' key with default value 'Display Graph'.

Specified by:

init in interface Component

Parameters:

map - property set to initialize the algorithm with.

prototype

public DisplayAll prototype()

Description copied from interface: Component

All Components implement the prototype pattern. The new parameter has no common resources to the original that are not static resources o the class.

Specified by:

prototype in interface Component

Specified by:

prototype in interface Algorithm

Returns:

default-parameter version of the same class as the original.

getCategoryPalette

public static int[] getCategoryPalette(int size,
                                       float s1,
                                       float s2,
                                       float b,
                                       float a)

Stolen from BSD licensed Jung2 toolkit. Copyright authors of the original //TODO: Restore original BSD license to this procedure Returns a color palette of given size tries to provide colors appropriate as category labels. There are 12 basic color hues (red, orange, yellow, olive, green, cyan, blue, purple, magenta, and pink). If the size is greater than 12, these colors will be continually repeated, but with varying saturation levels.

Parameters:

size - the size of the color palette

s1 - the initial saturation to use

s2 - the final (most distant) saturation to use

b - the brightness value to use

a - the alpha value to use
