Class SyscallManager

java.lang.Object

mars.mips.instructions.SyscallManager

public class SyscallManager
extends Object

This class provides functionality to bring external Syscall definitions into MARS. This permits anyone with knowledge of the MARS public interfaces, in particular of the Memory and Register classes, to write custom MIPS syscall functions. This is adapted from the ToolManager class, which is in turn adapted from Bret Barker's GameServer class from the book "Developing Games In Java".

Returns:

An array of Syscall instances.
