Constructor Detail

MandelbrotTaskImpl

public MandelbrotTaskImpl(double startX,
                          double startY,
                          double width,
                          int split,
                          int max)

Constructor accepting the arguements to create the set.

Parameters:

startX - The lower left x-coordinate of the region.

startY - The lower left y-coordinate of the region.

width - The width of the square.

split - The number of times to split the square.

max - The number of iterations ("black" regions).

Method Detail

setTaskId

public void setTaskId(TaskId value)

Description copied from class: Task

Assign the associated TaskId.

Overrides:

setTaskId in class Task

Parameters:

value - The TaskId to set.

getTaskId

public TaskId getTaskId()

Description copied from class: Task

Return the associated TaskId

Overrides:

getTaskId in class Task

Returns:

The assigned TaskId.

getStartX

public double getStartX()

getStartY

public double getStartY()

getWidth

public double getWidth()

getSplit

public int getSplit()

getMax

public int getMax()

execute

public java.lang.Object execute(java.lang.Object input)

Execute the task. The input object defines the lower bound of the split. If below the lower bound, the task computes the values. Otherwise it splits the region into four equal sections.

Overrides:

execute in class Task

Parameters:

input - The shared input set by the client

Returns:

The computed result.

runMandelbrot

public java.lang.Object runMandelbrot()

Executes the Mandelbrot set on the current values.

Returns:

Two dimensional array of integers.

abs

public static double abs(double a,
                         double bi)
