Detailed Description

A base class defining a common interface for all classes having a unique id.

Have a look at RichPeak2D for an example how to extend a class to support unique ids.

Member Enumeration Documentation

◆ anonymous enum

anonymous enum

This is the invalid unique id (cast it to a UInt64 if you like)

It is represented as an enum because static class members lead to bugs and linker errors all the time...

Constructor & Destructor Documentation

◆ UniqueIdInterface() [1/3]

UniqueIdInterface ( )
inline

Default constructor - the unique id will be invalid

◆ UniqueIdInterface() [2/3]

UniqueIdInterface ( const UniqueIdInterface rhs)
default

Copy constructor - copies the unique id.

◆ UniqueIdInterface() [3/3]

UniqueIdInterface ( UniqueIdInterface &&  rhs)
default

Move constructor.

◆ ~UniqueIdInterface()

virtual ~UniqueIdInterface ( )
virtualdefault

Destructor.

Member Function Documentation

◆ clearUniqueId()

Size clearUniqueId ( )
inline

Clear the unique id. The new unique id will be invalid. Returns 1 if the unique id was changed, 0 otherwise.

Referenced by RichPeak2D::operator=(), and RichPeak2D::RichPeak2D().

◆ ensureUniqueId()

Size ensureUniqueId ( )
inline

Assigns a valid unique id, but only if the present one is invalid. Returns 1 if the unique id was changed, 0 otherwise.

References UniqueIdGenerator::getUniqueId().

Referenced by MRMTransitionGroupPicker::createMRMFeature().

◆ getUniqueId()

UInt64 getUniqueId ( ) const
inline

Non-mutable access to unique id - returns the unique id.

Referenced by TOPPGNPSExport::main_(), FeatureHandle::IndexLess::operator()(), and ConfidenceScoring::scoreMap().

◆ hasInvalidUniqueId()

Size hasInvalidUniqueId ( ) const
inline

Returns whether the unique id is invalid. Returns 1 if the unique id is invalid, 0 otherwise.

◆ hasValidUniqueId()

Size hasValidUniqueId ( ) const
inline

Returns whether the unique id is valid. Returns 1 if the unique id is valid, 0 otherwise.

◆ isValid()

static bool isValid ( UInt64  unique_id)
inlinestatic

Returns true if the unique_id is valid, false otherwise.

Currently, an invalid unique id is represented by UInt64(0), but please prefer using this method for clarity.

Referenced by UniqueIdIndexer< RandomAccessContainer >::resolveUniqueIdConflicts(), and UniqueIdIndexer< RandomAccessContainer >::updateUniqueIdToIndex().

◆ operator=() [1/2]

UniqueIdInterface& operator= ( UniqueIdInterface &&  ) &
default

Move Assignment operator - copies the unique id.

◆ operator=() [2/2]

UniqueIdInterface& operator= ( UniqueIdInterface const &  rhs)
default

Assignment operator - copies the unique id.

◆ operator==()

bool operator== ( UniqueIdInterface const &  rhs) const
inline

Equality comparison operator - the unique ids must be equal (!)

References UniqueIdInterface::unique_id_.

Referenced by RichPeak2D::operator==().

◆ setUniqueId() [1/3]

Size setUniqueId ( )
inline

Assigns a new, valid unique id. Always returns 1.

References UniqueIdGenerator::getUniqueId().

◆ setUniqueId() [2/3]

void setUniqueId ( const String rhs)

Mutable access to unique id.

This is designed to work well with id attributes in XML, which are prefixed with letters. The portion of the String after the last underscore is extracted and parsed as a UInt64. It must consist of digits only. For example, some_feature.setUniqueId("f_12345_00067890") is equivalent to some_feature.setUniqueId(67890)

◆ setUniqueId() [3/3]

void setUniqueId ( UInt64  rhs)
inline

Assigns the given unique id.

◆ swap()

void swap ( UniqueIdInterface from)
inline
