Detailed Description

Base class for most itk classes.

Object is the second-highest level base class for most itk objects. It extends the base object functionality of LightObject by implementing callbacks (via object/observer), debug flags/methods, and modification time tracking. Most ITK classes should be a subclas of Object due to the need to keep track of modified time.

Member Function Documentation

unsigned long itk::Object::AddObserver ( const EventObject & event,

Command *

) const

Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

unsigned long itk::Object::AddObserver ( const EventObject & event,

Command *

)

Allow people to add/remove/invoke observers (callbacks) to any ITK object. This is an implementation of the subject/observer design pattern. An observer is added by specifying an event to respond to and an itk::Command to execute. It returns an unsigned long tag which can be used later to remove the event or retrieve the command. The memory for the Command becomes the responsibility of this object, so don't pass the same instance of a command to two different objects

virtual LightObject::Pointer itk::Object::CreateAnother ( ) const [virtual]

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.
Reimplemented from itk::LightObject.

virtual void itk::Object::DebugOff ( ) const [virtual]

Turn debugging output off.

virtual void itk::Object::DebugOn ( ) const [virtual]

Turn debugging output on.

Command* itk::Object::GetCommand ( unsigned long tag )

Get the command associated with the given tag. NOTE: This returns a pointer to a Command, but it is safe to asign this to a Command::Pointer. Since Command inherits from LightObject, at this point in the code, only a pointer or a reference to the Command can be used.

bool itk::Object::GetDebug ( ) const

Get the value of the debug flag.

bool itk::Object::GetGlobalWarningDisplay ( ) [static]

This is a global flag that controls whether any debug, warning or error messages are displayed.

const MetaDataDictionary& itk::Object::GetMetaDataDictionary ( void ) const

Returns:
A constant reference to this objects MetaDataDictionary.

MetaDataDictionary& itk::Object::GetMetaDataDictionary ( void )

Returns:
A reference to this objects MetaDataDictionary.

Warning:
This reference may be changed.

void itk::Object::GlobalWarningDisplayOff ( ) [inline, static]

This is a global flag that controls whether any debug, warning or error messages are displayed.
Definition at line 100 of file itkObject.h.

void itk::Object::GlobalWarningDisplayOn ( ) [inline, static]

This is a global flag that controls whether any debug, warning or error messages are displayed.
Definition at line 98 of file itkObject.h.

bool itk::Object::HasObserver ( const EventObject & event ) const

Return true if an observer is registered for this event.

void itk::Object::InvokeEvent ( const EventObject & ) const

Call Execute on all the Commands observing this event id. The actions triggered by this call doesn't modify this object.

void itk::Object::InvokeEvent ( const EventObject & )

Call Execute on all the Commands observing this event id.

bool itk::Object::PrintObservers ( std::ostream & os,

Indent indent

) const [protected]

virtual void itk::Object::Register ( ) const [virtual]

Increase the reference count (mark as used by another object).
Reimplemented from itk::LightObject.

void itk::Object::RemoveAllObservers ( )

Remove all observers .

void itk::Object::RemoveObserver ( unsigned long tag )

Remove the observer with this tag value.

void itk::Object::SetDebug ( bool debugFlag ) const

Set the value of the debug flag. A non-zero value turns debugging on.

void itk::Object::SetGlobalWarningDisplay ( bool flag ) [static]

This is a global flag that controls whether any debug, warning or error messages are displayed.

void itk::Object::SetMetaDataDictionary ( const MetaDataDictionary & rhs )

Returns:
Set the MetaDataDictionary

virtual void itk::Object::SetReferenceCount ( int ) [virtual]

Sets the reference count (use with care)
Reimplemented from itk::LightObject.

virtual void itk::Object::UnRegister ( ) const [virtual]

Decrease the reference count (release by another object).
Reimplemented from itk::LightObject.
