Namespaces
namespace	moab
	Class representing axis-aligned bounding box.
Defines
#define	MB_TYPE_WIDTH   4
#define	MB_ID_WIDTH   ( 8 * sizeof( EntityHandle ) - MB_TYPE_WIDTH )
#define	MB_TYPE_MASK   ( (EntityHandle)0xF << MB_ID_WIDTH )
#define	MB_START_ID   ( (EntityID)1 )
	All entity id's currently start at 1.
#define	MB_END_ID   ( (EntityID)MB_ID_MASK )
	Last id is the complement of the MASK.
#define	MB_ID_MASK   ( ~MB_TYPE_MASK )
Functions
EntityHandle	moab::CREATE_HANDLE (const unsigned type, const EntityID id, int &err)
	Given a type and an id create a handle.
EntityHandle	moab::CREATE_HANDLE (const unsigned type, const EntityID id)
EntityHandle	moab::FIRST_HANDLE (unsigned type)
EntityHandle	moab::LAST_HANDLE (unsigned type)
EntityID	moab::ID_FROM_HANDLE (EntityHandle handle)
	Get the entity id out of the handle.
EntityType	moab::TYPE_FROM_HANDLE (EntityHandle handle)
	Get the type out of the handle. Can do a simple shift because handles are unsigned (therefore shifting fills with zero's)

#define MB_TYPE_MASK   ( (EntityHandle)0xF << MB_ID_WIDTH )

Definition at line 47 of file Internals.hpp.

#define MB_TYPE_WIDTH   4

Define EntityHandle for both 32 bit and 64 bit systems. The decision to use 64 bit handles must be made at compile time.

EntityHandle format: 0xXYYYYYYY (assuming a 32-bit handle. Top 4 bits reserved on a 64 bit system) X - reserved for entity type. This system can only handle 15 different types Y - Entity id space. Max id is over 200M

Note that for specialized databases (such as all hex) 16 bits are not required for the entity type and the id space can be increased to over 2B.
