Detailed Description

The class for representing a resource.

This class represents a resource. It also contains the mutex for the resource (that can be shared among resources) and the list of objects that have to be notified when the resource changes. See the ResourcesUser class and its sublcasses for more information on resources

Definition at line 189 of file resource.h.

Constructor & Destructor Documentation

ResourceHandler ( QString name )

Constructor.

This creates a non-existing resource

Parameters

name	the name of the resource. This cannot be changed once set here in the constructor

Definition at line 68 of file resource.cpp.

~ResourceHandler ( )

Destructor.

Definition at line 76 of file resource.cpp.

Member Function Documentation

void addNotifee ( ResourcesUser * n )

Adds a new observer.

Parameters

n	the object that will be notified when this resource changes

Definition at line 148 of file resource.cpp.

Referenced by ConcurrentResourcesUser::addUsableResource(), ConcurrentResourcesUser::addUsableResources(), ConcurrentResourcesUser::shareResourcesWith(), and ConcurrentResourcesUser::usableResources().

bool exists ( ) const

inline

Returns true if this holds an existing resource.

Returns: true if this holds an existing resource

Definition at line 327 of file resource.h.

Referenced by ConcurrentResourcesUser::addUsableResource(), ConcurrentResourcesUser::addUsableResources(), ConcurrentResourcesUser::declareResource(), SimpleResourcesUser::deleteResource(), ConcurrentResourcesUser::deleteResource(), SimpleResourcesUser::getResource(), ConcurrentResourcesUser::getResource(), ConcurrentResourcesUser::removeAllUsableResources(), ConcurrentResourcesUser::removeUsableResources(), ConcurrentResourcesUser::usableResources(), and ConcurrentResourcesUser::usedResourcesExist().

T* get ( ) const

inline

The function to obtain the resource.

Specialization for primitive types are implemented after the class because we cannot explitly specialize a function in a non-namespace

Returns: the resource or NULL if the type is not compatible

QMutex& getLock ( )

inline

Returns the mutex for this resource.

Returns: a reference to the mutex for this resource

Definition at line 317 of file resource.h.

bool isNotifee ( ResourcesUser * n ) const

Returns true if n is an observer for this resource.

Parameters

n	the object that will be searched in the set of observers

Returns: true if n is an observer for this resource

Definition at line 158 of file resource.cpp.

QString name ( ) const

inline

Returns the name of the resource.

Returns: the name of the resource

Definition at line 211 of file resource.h.

void removeNotifee ( ResourcesUser * n )

Removes an observer.

Parameters

n	the object that will be no longer notified when this resource changes

Definition at line 153 of file resource.cpp.

Referenced by ConcurrentResourcesUser::removeAllUsableResources(), ConcurrentResourcesUser::removeUsableResource(), and ConcurrentResourcesUser::removeUsableResources().

void set ( int * res )

The set method for an int resource.

This also notifes all observers of this resource

Parameters

res	the int resource to set

Definition at line 85 of file resource.cpp.

Referenced by SimpleResourcesUser::declareResource(), and ConcurrentResourcesUser::declareResource().

void set ( float * res )

The set method for a float resource.

This also notifes all observers of this resource

Parameters

res	the float resource to set

Definition at line 93 of file resource.cpp.

void set ( double * res )

The set method for a double resource.

This also notifes all observers of this resource

Parameters

res	the double resource to set

Definition at line 101 of file resource.cpp.

void set ( bool * res )

The set method for a bool resource.

This also notifes all observers of this resource

Parameters

res	the bool resource to set

Definition at line 109 of file resource.cpp.

void set ( Resource * res )

The set method for a Resource resource.

This also notifes all observers of this resource

Parameters

res	the Resource resource to set

Definition at line 117 of file resource.cpp.

void set ( ParameterSettable * res )

The set method for a ParameterSettable resource.

This also notifes all observers of this resource

Parameters

res	the ParameterSettable resource to set

Definition at line 125 of file resource.cpp.

void set ( QObject * res )

The set method for a QObject resource.

This also notifes all observers of this resource

Parameters

res	the QObject resource to set

Definition at line 133 of file resource.cpp.

void shareLockWith ( ResourceHandler * other )

Shares the lock with the other resource.

After a call to this function, this and "other" will share the same mutex object. This is transitive, so if "other" already shared the mutex with some other resources, this will share the mutex with those other resources as well

Parameters

other the object sharing its lock

Definition at line 80 of file resource.cpp.

Referenced by ConcurrentResourcesUser::declareResource().

void unset ( )

Marks this resource as non-existing.

This also notifes all observers of this resource

Definition at line 141 of file resource.cpp.
