Detailed Description

Provides unique identification for elements.

Author:

Raphael Langerhorst

Do NOT use ID 0 for elements, it represents "no ID".

Constructor & Destructor Documentation

GCS::GElementID::GElementID (   )  [inline, private]

For some reason QValueListNode requires a default constructor. to avoid instantiation without a value everywhere else this constructor is private. Todo: This is a workaround and should be removed as soon as Qt does not depend on such a constructor for QValueList anymore.

GCS::GElementID::GElementID (  unsigned long  ID  )  [inline]

Public constructor initializes to given ID.

GCS::GElementID::GElementID (  const GElementID &  original  )  [inline]

Copy constructor.

---

Member Function Documentation

unsigned long GCS::GElementID::getID (   )  const [inline]

Returns: copy of the ID.

bool GCS::GElementID::operator!= (  const GElementID &  id  )  const [inline]

This enables comparing of element IDs. Returns: true when both GElementID objects have different IDs.

bool GCS::GElementID::operator== (  const GElementID &  id  )  const [inline]

This enables comparing of element IDs. Returns: true when both GElementID objects have the same ID.

Friends And Related Function Documentation

friend class QValueListNode< GElementID > [friend]

Gives QValueListNode access to the private default constructor - see GElementID() for details.

Member Data Documentation

IDRange GCS::GElementID::FreeIDs [static, private]

The Range of free IDs Todo: as soon as the server side is split up in more processes then this must be a pointer list with many ranges as the GWE needs to add ranges.

unsigned long GCS::GElementID::ID [private]

The ID is represented by an unsigned long integer.
