Comments:
This is an implementation or body class. As a result the handle class
RegBoundaryC should be used.
Used by RegOrderedGrowC to represent intermediate stages in the region
growing process. It stores a labelled image of the region as well as
statistics of the region and boundary. The statistics are updated
incrementally when a pixel is added to the region.
Parent Classes:
Enumerated types:
Variables:
Methods:
- RegBoundaryBC(const ImageRectangleC & rect,const NumLabelC & label)
-
Constructor
| ind | Index of types of intererest. |
- RegBoundaryBC(const RegBoundaryBC & oth)
-
Copy constructor clips label image
| ind | Index of types of intererest. |
Makes a completely new copy.
- RegBoundaryBC & Copy() const
-
Makes a deep copy
| ind | Index of types of intererest. |
- void AddReference()
-
Another reference to the object has been created.
- void RemoveReference()
-
One reference to the object was deleted.
Locking scheme
--------------
The object is possible to lock (to make constant). The scheme
assumes that the object is created, it can be locked, after that
it can only be destroyed. The locked object cannot be unlocked.
This locking scheme is very useful
during debugging, using assert() function,
when it is necassary to check that object
is treated as constant and the constancy is not violated by
any casting or passing through the copy constructor of shared
objects.
- void SetConst(void) const
-
This locks the object.
Often objects you wish to lock are already const.
- void SetConst(void)
-
This locks the object.
- BooleanT IsConst(void) const
-
Returns TRUE if the object is locked, ie. it is assumed to be constant.
- BooleanT IsNotConst(void) const
-
Returns TRUE if the object is unlocked.
ie. there is no special
information if the object is constant or not.
Counter state information
-------------------------
- BooleanT ToBeDeleted() const
-
Returns TRUE if there is only one reference to the object and the whole object or its reference counting part can be deleted.
- BooleanT ToBeDeletedRemoveIgnoreNoRemove()
-
Decrement refrence by 1 return true if this leaves no refrences to the object.
- BooleanT ToBeDeletedRemove()
-
Decrement refrence by 1 return true if this leaves no refrences to the object. This also checks the NoRemove flag.
- BooleanT BodyMightBeDeleted() const
-
Returns TRUE if the reference counted part of the object can be deleted, ie. flag NOREMOVE is false .
- BooleanT IsCountZero() const
-
Are there any refrences left ?
- BooleanT BRCPtrCanDeleteObject() const
-
Used by BRRCPtrC to establish if an object has ZERO refrences and can be deleted.
- IntT Count() const
-
Returns the current state of the counter, ie. how many references to this object exist.
- const BodyRefCounterC & operator=(const BodyRefCounterC & b)
-
It has not meaning to assign object 'b' to this object because it would destroy a history of the object which is counted. So this is a dummy function.
- BooleanT IsValidObject() const
-
Test if object is valid.
When amma check is disabled this always returns true.
- BooleanT UserBitTest(IntT x) const
-
Test user flag.
- void UserBitSet(IntT x,BooleanT setit = TRUE)
-
Test user flag.
- void UserBitZero(IntT x)
-
Set bit to zero.
- void ReportBRCError(char * Msg)
-
Report error, used in BRCPtrC.
- UIntT Hash() const
-
Hash on address of object.
- LabelT Label() const
-
Returns the label of this reference counter.
The member function
is useful mainly to recognize objects during debugging.
The value of the label is uniquely defined pointer.
