setMode

public void setMode(TaskRegistry.PrecisionMode mode)

getInputType

public Class<NBodyTask> getInputType()

Description copied from interface: DistributedTask

Returns the expected input type class.

Used for deserialization and type checking during task dispatch.

Specified by:

getInputType in interface DistributedTask<NBodyTask, NBodyTask>

Returns:

the Class object representing the input type

getOutputType

public Class<NBodyTask> getOutputType()

Description copied from interface: DistributedTask

Returns the expected output type class.

Used for serialization and type checking during result collection.

Specified by:

getOutputType in interface DistributedTask<NBodyTask, NBodyTask>

Returns:

the Class object representing the output type

execute

public NBodyTask execute(NBodyTask input)

Description copied from interface: DistributedTask

Executes the computation for the given input chunk.

This method contains the core scientific algorithm. It receives a chunk of input data and returns the computed result. The infrastructure handles serialization, network transfer, and result aggregation.

Specified by:

execute in interface DistributedTask<NBodyTask, NBodyTask>

Parameters:

input - the input data for this computation chunk

Returns:

the computed result

getTaskType

public String getTaskType()

Description copied from interface: DistributedTask

Returns the unique task type identifier.

This identifier is used by the task registry to locate and instantiate the appropriate task implementation. Examples: "MANDELBROT", "PROTEIN_FOLDING", "N_BODY", "CLIMATE_MODEL".

Specified by:

getTaskType in interface DistributedTask<NBodyTask, NBodyTask>

Returns:

the task type identifier (non-null, uppercase with underscores)

step

public void step()

getBodies

public List<NBodyTask.Body> getBodies()
