Abstract

This class provides meta-information about database objects such as tables and indexes. Object subclasses model these and other database objects.

Parent class.  NdbDictionary

Child classes.  Datafile, Event, Index, LogfileGroup, Table, Tablespace, Undofile, HashMap, ForeignKey

Methods.  The following table lists the public methods of the Object class and the purpose or use of each method:

Method	Purpose / Use
getObjectId()	Gets an object's ID
getObjectStatus()	Gets an object's status
getObjectVersion()	Gets the version of an object

Note

All 3 of these methods are pure virtual methods, and are reimplemented in the Table, Index, and Event subclasses where needed.

Types.  These are the public types of the Object class:

Type	Purpose / Use
FragmentType	Fragmentation type used by the object (a table or index)
State	The object's state (whether it is usable)
Status	The object's state (whether it is available)
Store	Whether the object has been temporarily or permanently stored
Type	The object's type (what sort of table, index, or other database object the Object represents)

This diagram shows all public members of the Object class:
