Usage in object oriented programming languages

Java
// init CLIJ and GPU
import net.haesleinhuepf.clij2.CLIJ2;
import net.haesleinhuepf.clij.clearcl.ClearCLBuffer;
CLIJ2 clij2 = CLIJ2.getInstance();

// get input parameters
ClearCLBuffer values = clij2.push(valuesImagePlus);
ClearCLBuffer touch_matrix = clij2.push(touch_matrixImagePlus);
minimum_values_destination = clij2.create(values);
// Execute operation on GPU
clij2.minimumOfTouchingNeighbors(values, touch_matrix, minimum_values_destination);
// show result
minimum_values_destinationImagePlus = clij2.pull(minimum_values_destination);
minimum_values_destinationImagePlus.show();

// cleanup memory on GPU
clij2.release(values);
clij2.release(touch_matrix);
clij2.release(minimum_values_destination);
Matlab
% init CLIJ and GPU
clij2 = init_clatlab();

% get input parameters
values = clij2.pushMat(values_matrix);
touch_matrix = clij2.pushMat(touch_matrix_matrix);
minimum_values_destination = clij2.create(values);
% Execute operation on GPU
clij2.minimumOfTouchingNeighbors(values, touch_matrix, minimum_values_destination);
% show result
minimum_values_destination = clij2.pullMat(minimum_values_destination)

% cleanup memory on GPU
clij2.release(values);
clij2.release(touch_matrix);
clij2.release(minimum_values_destination);
Icy JavaScript
// init CLIJ and GPU
importClass(net.haesleinhuepf.clicy.CLICY);
importClass(Packages.icy.main.Icy);

clij2 = CLICY.getInstance();

// get input parameters
values_sequence = getSequence();
values = clij2.pushSequence(values_sequence);
touch_matrix_sequence = getSequence();
touch_matrix = clij2.pushSequence(touch_matrix_sequence);
minimum_values_destination = clij2.create(values);
// Execute operation on GPU
clij2.minimumOfTouchingNeighbors(values, touch_matrix, minimum_values_destination);
// show result
minimum_values_destination_sequence = clij2.pullSequence(minimum_values_destination)
Icy.addSequence(minimum_values_destination_sequence);
// cleanup memory on GPU
clij2.release(values);
clij2.release(touch_matrix);
clij2.release(minimum_values_destination);
