Detailed Description

Hash table to manage integral label equivalencies.

EquivalencyTable is a hash table for recording equivalencies among unsigned long integer values. EquivalencyTable can store recursive relationships (8=7, 7=6, 6=5, ...) or be ``flattened'' to eliminate recursion. The table uses an efficient algorithm for eliminating redundancy and preventing circular dependencies.

In the context of the watershed segmentation algorithm (itk::WatershedImageFilter), this table is used to store connections identified among image segments and as the input to itk::watershed::Relabeler.

Member Function Documentation

bool itk::EquivalencyTable::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).

bool itk::EquivalencyTable::AddAndFlatten ( unsigned long  a,
unsigned long  b 
)

Insert an equivalency into the table and flatten that equivalency. 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::EquivalencyTable::Begin ( )
inline

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

Definition at line 130 of file itkEquivalencyTable.h.

void itk::EquivalencyTable::Clear ( )
inline

Erases all the entries in the table.

Definition at line 117 of file itkEquivalencyTable.h.

virtual::itk::LightObject::Pointer itk::EquivalencyTable::CreateAnother ( void  ) const
virtual

Standard smart pointer declarations

Reimplemented from itk::Object.

bool itk::EquivalencyTable::Empty ( ) const
inline

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

Definition at line 121 of file itkEquivalencyTable.h.

Iterator itk::EquivalencyTable::End ( )
inline

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

Definition at line 134 of file itkEquivalencyTable.h.

void itk::EquivalencyTable::Erase ( const unsigned long  a)
inline

Erases the entry with key a.

Definition at line 113 of file itkEquivalencyTable.h.

void itk::EquivalencyTable::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::EquivalencyTable::GetNameOfClass ( ) const
virtual

Standard smart pointer declarations

Reimplemented from itk::DataObject.

bool itk::EquivalencyTable::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 105 of file itkEquivalencyTable.h.

unsigned long itk::EquivalencyTable::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 89 of file itkEquivalencyTable.h.

Standard smart pointer declarations

void itk::EquivalencyTable::operator= ( const Self )
protected
void itk::EquivalencyTable::PrintSelf ( std::ostream &  os,
Indent  indent 
) const
protectedvirtual

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::EquivalencyTable::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.

HashTableType::size_type itk::EquivalencyTable::Size ( void  ) const
inline

Returns the number of entries in the table.
