Detailed Description

Hash table to manage integral label equivalencies that are order dependent.

OneWayEquivalencyTable is a variation on itk::EquivalencyTable that preserves the order of equivalencies. For example, the entries { 5 = 4 } and {4 = 5} are not equivalent in this table, yet are the treated as the same entry in EquivalencyTable. Because of the one-way logic of the table, reflexive equivalencies will result in cycling from recursive lookups or flattening of the table. The responsibility is on the user for preventing recursive cycling.

Member Function Documentation

bool itk::OneWayEquivalencyTable::Add	(	unsigned long	a,
		unsigned long	b
	)

Insert an equivalency into the table. A return value of TRUE indicates that the equivalency did not previously exist in the table and was successfully added. A FALSE return value indicates that the equivalency was not added to the table because a conflict with an existing entry occurred (most likely, the equivalency was already recorded directly or indirectly).

Iterator itk::OneWayEquivalencyTable::Begin ( void  )

inline

Returns an iterator pointing to the first element of the (unordered) table.

Definition at line 120 of file itkOneWayEquivalencyTable.h.

void itk::OneWayEquivalencyTable::Clear ( void  )

inline

Erases all the entries in the table.

Definition at line 111 of file itkOneWayEquivalencyTable.h.

virtual

Standard typedefs and smart pointer declarations.

Reimplemented from itk::Object.

bool itk::OneWayEquivalencyTable::Empty ( ) const

inline

Returns TRUE if the table is empty, FALSE if it is not empty.

Definition at line 115 of file itkOneWayEquivalencyTable.h.

Iterator itk::OneWayEquivalencyTable::End ( )

inline

Returns and iterator pointing to one position past the last element of the (unordered) table.

Definition at line 124 of file itkOneWayEquivalencyTable.h.

void itk::OneWayEquivalencyTable::Erase ( const unsigned long  a )

inline

Erases the entry with key a.

Definition at line 107 of file itkOneWayEquivalencyTable.h.

void itk::OneWayEquivalencyTable::Flatten

(

)

"Flattens" the equivalency table by eliminating all redundant and recursive equivalencies. I.e. the set { 2=1; 3=2; 4=3 } is converted to {4=1; 3=1; 2=1}.

virtual const char* itk::OneWayEquivalencyTable::GetNameOfClass ( ) const

virtual

Standard typedefs and smart pointer declarations.

Reimplemented from itk::DataObject.

bool itk::OneWayEquivalencyTable::IsEntry ( const unsigned long  a ) const

inline

Returns TRUE if the label is found in the table and FALSE is the label is not found in the table.

Definition at line 99 of file itkOneWayEquivalencyTable.h.

unsigned long itk::OneWayEquivalencyTable::Lookup ( const unsigned long  a ) const

inline

Lookup an equivalency in the table. If no entry is found in the table, the method returns its the value of the argument. Does not recursively descent through equivalencies.

Definition at line 83 of file itkOneWayEquivalencyTable.h.

static Pointer itk::OneWayEquivalencyTable::New ( )

static

Standard typedefs and smart pointer declarations.

virtual void itk::OneWayEquivalencyTable::PrintSelf ( std::ostream &  os, Indent  indent  ) const

overrideprotectedvirtual

Methods invoked by Print() to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from itk::DataObject.

unsigned long itk::OneWayEquivalencyTable::RecursiveLookup

(

const unsigned long

a

)

const

Lookup an equivalency in the table by recursing through all successive equivalencies. For example, if the follow entries exist in the table {8=7, 7=6, 6=5}, then RecursiveLookup(8) returns 5.
