Class QueuedAutomaton

  +--gecco.server.qmanager.QueuedAutomaton

All Implemented Interfaces:

Comparable

public class QueuedAutomaton

extends Object

implements Comparable

This class encapsulates data about an automaton in the queue of the server. It consists of data about which automaton it is, that is, the position on the map, and data about which place in the queue it has, that is, the time until the automaton should be taken from the queue and processed in some way.

Constructor Summary

QueuedAutomaton(int x, int y, double absoluteTimeToExecute)
Constructor for the QueuedAutomaton object

Method Summary

int	compareTo(Object a) Compares this automaton with a given automaton.
boolean	equals(Object a) Tests whether to QueuedAutomatons are equal, which is true iff they have the same coordinates and the same time for process.
double	getTimeToExecute() Gets the time when the automaton shoule be processed.
int	getX() Gets the x coordinate of the automaton
int	getY() Gets the y coordinate of the automaton
void	setTimeToExecute(double newTimeToExecute) Sets the time when the automaton should be processed.

Constructor Detail

QueuedAutomaton

public QueuedAutomaton(int x,
                       int y,
                       double absoluteTimeToExecute)

Constructor for the QueuedAutomaton object

Parameters:

x - The x-coordinate of the automaton

y - The x-coordinate of the automaton

absoluteTimeToExecute - The time when the automaton should be processed. This is absolute game time, _not_ a relative time from the current time.

Method Detail

setTimeToExecute

public void setTimeToExecute(double newTimeToExecute)

Sets the time when the automaton should be processed.

Parameters:

newTimeToExecute - The new TimeToExecute value

getX

public int getX()

Gets the x coordinate of the automaton

Returns:

The x coordinate

getY

public int getY()

Gets the y coordinate of the automaton

Returns:

The y coordinate

getTimeToExecute

public double getTimeToExecute()

Gets the time when the automaton shoule be processed.

Returns:

The time (absolute)

equals

public boolean equals(Object a)

Tests whether to QueuedAutomatons are equal, which is true iff they have the same coordinates and the same time for process. This method obeys the general contract of the Comparable interface.

Overrides:

equals in class Object

Parameters:

a - Should be a QueuedAutomaton

Returns:

true if a is equal to this automaton, false otherwise

compareTo

public int compareTo(Object a)

Compares this automaton with a given automaton. An automaton is considered less than an other automaton if at least one of the following conditions are satisfied. a) the time for process is less, that is, earlier b) the x coordinate is less c) the y coordinate is less The checks are performed in the above order. This method obeys the general contract of the Comparable interface.

Specified by:

compareTo in interface Comparable

Parameters:

a - Should be a QueuedAutomaton

Returns:

-1 if this automaton is less than a, 0 if the automatons are equal, 1 if a is greater than this automaton
