SequentialPlan
public SequentialPlan()Creates a new empty sequential plan.- See Also:
AbstractPlan()
-
SequentialPlan
Creates a new sequential plan from an other. This constructor creates a deep copy of the specified plan.- Parameters:
other
- the other plan.- See Also:
AbstractPlan(Plan)
-
-
Method Details
-
makespan
public final double makespan()Returns the makespan of the plan. The makespan of a sequential plan is its size.- Returns:
- the makespan of the plan.
- See Also:
Plan.size()
-
actions
Returns the list of actions contained in the plan ordered depending on their time specifier.- Returns:
- the ordered set of actions of the plan.
- See Also:
Plan.actions()
-
timeSpecifiers
Returns the set of time specifiers used in this plan.- Returns:
- the set of time specifiers used in this plan.
- See Also:
Plan.timeSpecifiers()
-
getActionSet
Returns the set of actions at a specified time specifier.- Parameters:
time
- the time specifier.- Returns:
- the set of actions at a specified time specifier or null if no actions are scheduled in the plan at the the time specifier.
- See Also:
Plan.getActionSet(int)
-
add
Adds an action at a specified time specifier in the plan.- Parameters:
action
- the action to add.time
- the time specifier of the action in the plan.- Returns:
true
if the action was added;false
otherwise.- See Also:
Plan.add(int, Action)
-
remove
Removes an action at a specified time specifier of the plan.- Parameters:
action
- the action to remove.time
- the time specifier of the action in the plan to remove.- Returns:
true
if the action was removed;false
otherwise.- See Also:
Plan.remove(int, Action)
-
remove
public final boolean remove(int time)Removes all the actions at a specified time specifier of the plan.- Parameters:
time
- the time specifier of the actions in the plan to remove.- Returns:
true
if the action was removed;false
otherwise.- See Also:
Plan.remove(int)
-
contains
Returns if an action is contained in the plan at a specified time specifier.- Parameters:
time
- the time specifier.action
- the action.- Returns:
true
if the specified action is contained in the plan at the specified time specifier;false
otherwise.- See Also:
Plan.contains(int, Action)
-
clear
public final void clear()Removes all the actions of the plan.- See Also:
Plan.clear()
-
equals
Returns if the plan is equal to an other object. A plan is equal to an other object if the object is an instance of the same class and have the same action at the same time specifier. The equals method uses the equal method of the class BitOp to compare actions.- Overrides:
equals
in classObject
- Parameters:
obj
- the object to be compared.- Returns:
true
if this plan is equal to the specified object;false
otherwise.- See Also:
AbstractInstantiatedOperator.equals(Object)
,Object.equals(Object)
-
hashCode
public int hashCode()Returns the hash code of this plan.- Overrides:
hashCode
in classObject
- Returns:
- the hash code of this plan.
- See Also:
Object.hashCode()
-
isTimeSpecifierOutOfBound
protected final boolean isTimeSpecifierOutOfBound(int time)Returns if a specified time specifier is invalid. Formally a time specifier is invalid if it is less than 0 or greater than the size of the plan.- Parameters:
time
- the time stamp.- Returns:
true
if the specified time specifier is out of bound;false
otherwise.
