Dictionary.
This protected data member holds the data dictionary reference.
DefaultOffsets() : array
Return default offsets
This method will return the list of default offsets for the current class, these are the properties known to be part of the current class: since objects may feature any defined tag, this selection provides an indication of which properties one could expect.
This selection can also be used as the minimum set of properties which an object may feature.
In this class we return an empty array.
List of default offsets.
getName(string $theLanguage) : string
Get object name
This method should return the object name, this value represents a name or label that characterises the current object.
Derived classes must overload this method.

__construct(mixed $theContainer, mixed $theIdentifier, boolean $doAssert)
Instantiate class.
Objects derived from this class share the same constructor prototype and should not overload this method.
The method accepts three parameters:
The workflow is as follows:
Any other combination will raise an exception.
This constructor sets the {@link isCommitted()} flag, derived classes should first call the parent constructor, then they should set the {@link isInited()} flag.

| mixed | $theIdentifier | Object identifier or properties. |
| boolean | $doAssert | Raise exception if not resolved. |
setAlias(boolean $doSet)
Signal object as alias
This method can be used to set or reset the object {@link isAlias()} flag, this signals that the current object is an alias of the object referenced by the {@link kTAG_MASTER} offset value: to set the status pass TRUE in the parameter and FALSE to reset it.
This method should only be called on non committed objects, once set, this status is immutable, so in that case the method will raise an exception.
When resetting the status, the method will also remove the eventual {@link kTAG_MASTER} attribute.
Note that not any object can be set as alias: objects that can take this state must feature a method that selects their master object, so you should shadow this method in derived classes that do not implement the concept of master and alias.
| boolean | $doSet | TRUE to set. |
ResolveDatabase(\OntologyWrapper\Wrapper $theWrapper, boolean $doAssert, boolean $doOpen) : \OntologyWrapper\DatabaseObject
Resolve the database
This method should return a {@link DatabaseObject} instance corresponding to the default database of the current class extracted from the provided {@link Wrapper} instance.

By default we include offsets returned by:
Note that internal offsets, {@link InternalOffsets()}, are also not managed, but since those offsets do not have a sequence number, we need to treat them separately.
Derived classes may overload this method to add custom offsets.
List of unmanaged offsets.
insert(\OntologyWrapper\Wrapper $theWrapper, \OntologyWrapper\bitfield $theOptions) : mixed
Insert the object
This method will insert the current object into the provided persistent store only if it doesn't exist already:

commit(\OntologyWrapper\Wrapper $theWrapper, \OntologyWrapper\bitfield $theOptions) : mixed
Commit the object
This method will insert or update the current object into the provided persistent store, the method expects a single parameter representing the wrapper, this can be omitted if the object was instantiated with a wrapper.
The method will call the {@link commitObject()} method if the object was not committed and the {@link updateObject()} method if it was.
The $doRelated parameter can be used to prevent the object from updating related objects. This can be useful when adding objects as batches: in that case it may be much faster to first add the objects and then at a later stage update them.
Do not overload this method, you should overload the methods called in this method.
| \OntologyWrapper\Wrapper | $theWrapper | Data wrapper. |
| \OntologyWrapper\bitfield | $theOptions | Operation options. |

The first parameter is the wrapper in which the current object is, or will be, stored: if the current object has the {@link dictionary()}, this parameter may be omitted; if the wrapper cannot be resolved, the method will raise an exception.
This method assumes that the {@link kTAG_MASTER} property is correctly set, if that is not the case, the method will return the current object, which may not be what you want.

This method will delete the object corresponding to the provided native identifier.
Deleting objects is a static matter, since, in order to ensure referential integrity, it is necessary to traverse an object which is a mirror of the persistent image. The methods which actually delete the object are declared protected, so that it should not be easy to delete an incomplete object.
This method should be called using the base class of the object one wants to delete, this means that either you know the class, or you may call this method from the object that you want to delete.
The method expects the following parameters:
The method will first load the object from the persistent store and then it will call its protected {@link deleteObject()} method, returning:
When loading the object only the {@link kTAG_NID}, {@link kTAG_OBJECT_OFFSETS} and {@link kTAG_OBJECT_REFERENCES} will be loaded, since these are the offsets that contain the necessary information for maintaining referential integrity, if you need to handle other object offsets, you should overload the static {@link DeleteFieldsSelection()} method.

insertObject(\OntologyWrapper\CollectionObject $theCollection, \OntologyWrapper\bitfield $theOptions) : mixed
Insert the object
This method will insert the current object into the provided persistent store only if not yet committed, the method will perform the following steps:
If any of the above steps fail the method must raise an exception.
Note that this method can only be called with objects that do not have native identifiers assigned by the database, oin that case all objects will appear to be new and will be inserted.
The $doRelated parameter can be used to prevent the object from updating related objects. This can be useful when adding objects as batches: in that case it may be much faster to first add the objects and then at a later stage update them.
Do not overload this method, you should overload the methods called in this method.
| \OntologyWrapper\CollectionObject | $theCollection | Data collection. |
| \OntologyWrapper\bitfield | $theOptions | Operation options. |

deleteObject() : mixed
Delete the object
This method will delete the current object from its persistent store, the method is declared protected, because it should not be called by clients: rather, the static {@link Delete()} method should be used for this purpose.
Deleting an object involves much more than simply removing the object from its container: all reference counts and tag offsets must be updated to maintain referential integrity, for this reason, this method should be called by an object which is {@link isCommitted()} and not {@link isDirty()}; if that is not the case, an exception will be raised.
The object only needs the {@link kTAG_NID}, {@link kTAG_OBJECT_OFFSETS} and {@link kTAG_OBJECT_REFERENCES} properties, these are the offsets loaded by the static {@link Delete()} method which calls this one; if derived classes need other properties, they should also modify the static {@link Delete()} method accordingly.
This method follows a workflow similar to the {@link commit()} method:
The method will return the object's native identifier if it was deleted; if the object is referenced, the method will return FALSE; if the object was not found in the container, the method will return NULL.
The $doRelated parameter can be used to prevent updating related objects.
You should overload the methods called in this method, not this method.
Native identifier, NULL or FALSE.

preCommitGraphReferences(\OntologyWrapper\DatabaseGraph $theGraph) : mixed
Load object in graph
This method is called by the {@link preCommitFinalise()} method, its duty is to load the object into the eventual graph

Derived classes should not overload this method, but rather the methods it calls; the only exception is if the object should not be stored in the graph: in that case overload the method to return FALSE.
If the method returns an integer, it means that the value represents the graph node identifier; if the method returns FALSE, it means that there will be no graph node.

The method will return TRUE if the object can be deleted, if any of the called methods do not return TRUE, the operation will be aborted.
