Method Summary

Methods

Modifier and Type	Method and Description
void	execute(DynamicByteArray bytecode, RoverMachineRegister register, RoverMachineActor actor) Execute the given bytecode with a RoverMachine, storing data in the given register and sending events to the given actor.
RoverBlock	readBlock(DynamicByteArray bytes) Read a block from the given byte array.
void	writeBlock(RoverBlock block, DynamicByteArray bytes) Write a block to the given byte array.

Method Detail

readBlock

RoverBlock readBlock(DynamicByteArray bytes)
                     throws RoverFormatException

Read a block from the given byte array.

Parameters:

bytes - encoded rover bytes

Returns:

block read

Throws:

RoverFormatException

writeBlock

void writeBlock(RoverBlock block,
              DynamicByteArray bytes)
                throws RoverFormatException

Write a block to the given byte array.

Parameters:

bytes - encoded rover bytes

Throws:

RoverFormatException

execute

void execute(DynamicByteArray bytecode,
           RoverMachineRegister register,
           RoverMachineActor actor)
             throws java.io.IOException

Execute the given bytecode with a RoverMachine, storing data in the given register and sending events to the given actor.

This method should be as fast as possible. Avoid allocations, external calls, or anything else that will compromise performance. Comment out log statements rather than testing for log.isDebugEnabled(). Etc.

Throws:

java.io.IOException
