All Implemented Interfaces:
NamedObjectOps

public class IntegerCondition extends Condition
Class for integer-valued conditions.
  • Constructor Details

    • IntegerCondition

      public IntegerCondition(DramaSimulation sim, String name, boolean intern) throws IllegalArgumentException
      Constructor.
      Parameters:
      sim - the simulation
      name - the name of the condition; null if generated
      intern - true if the object can be looked up by using the methods in Simulation; false otherwise.
      Throws:
      IllegalArgumentException - typically means a name is already in use
    • IntegerCondition

      public IntegerCondition(DramaSimulation sim, String name, boolean intern, int value) throws IllegalArgumentException
      Constructor with an initial value.
      Parameters:
      sim - the simulation
      name - the name of the condition; null for an automatically generated name
      intern - true if the object can be looked up by using the methods in Simulation; false otherwise.
      value - the initial value for the condition
      Throws:
      IllegalArgumentException - typically means a name is already in use
  • Method Details

    • getValue

      public int getValue()
      Get the value associated with this condition. Does not notify domains of a change in value.
      Returns:
      the condition's value
    • setValue

      protected void setValue(int value)
      Set the value associated with this condition Calling this method does not notify domains of the change. A subclass may have to override this method as follows:
      
            protected void setValue(int value) {
                super.setValue(value);
            }
       
      in order to make the method accessible to classes in the subclass' package.
      Parameters:
      value - the new value
    • clone

      protected Object clone() throws CloneNotSupportedException
      Creates and returns a copy of this object. This method will throw the exception CloneNotSupportedException if the object is interned.
      Overrides:
      clone in class Object
      Throws:
      CloneNotSupportedException - a clone could not be created

    • isInterned

      public boolean isInterned()
      Determine if an object is interned in a object namer's tables.
      Specified by:
      isInterned in interface NamedObjectOps
      Returns:
      true if the object is interned; false if not
    • getObjectNamer

      protected Simulation getObjectNamer()
      Get the object namer for a named object.
      Returns:
      the object namer for this named object
    • getName

      public final String getName()
      Get an object's name.
      Specified by:
      getName in interface NamedObjectOps
      Returns:
      the name of the object
    • canDelete

      public boolean canDelete()
      Determine if this named object can be deleted. A named object can be deleted if the method delete has not been called and if the object is not in a state that prevents the object from being deleted. Subclasses that override this method must call canDelete() for their superclasses and return false if the superclass' canDelete method returns false. The default method returns true if delete() has not been called and returned true.
      Specified by:
      canDelete in interface NamedObjectOps
      Returns:
      true if this object can be deleted; false otherwise
    • delete

      public final boolean delete()
      Delete an object. An object can only be deleted once. If this method returns true, the object (if interned) will have been removed from the object namer tables.

      The implementations provided by DefaultNamedObect and generated because of a @NamedObject annotation provide a protected method named onDelete. A subclass that overrides onDelete() must call the onDelete method of its superclass after it's onDelete method has been called and any cleanup actions performed. In some cases, this may happen at a later time (e.g., if a thread is used for some of the cleanup operations or if it is otherwise necessary to wait).

      Specified by:
      delete in interface NamedObjectOps
      Returns:
      true if the deletion request was accepted; false otherwise
    • isDeleted

      public final boolean isDeleted()
      Determine if an object has been deleted. An object is deleted if the method delete() has been called and returned true.
      Specified by:
      isDeleted in interface NamedObjectOps
      Returns:
      true if deleted; false otherwise
    • deletePending

      public final boolean deletePending()
      Determine if an object is being deleted. An deletion is pending if the method delete() has been called and returned true but the deletion has not been completed.
      Specified by:
      deletePending in interface NamedObjectOps
      Returns:
      true if deletion is pending; false otherwise
