Detailed Description

A class each application has to implement. It is used to contain the application data. This abstract class, alongwith Label, is one of the cornerstones of Model Editor. The groundwork is to define the root of information. This information is to be attached to a Label, and could be of any of the following types:

Contents:

Each software component who'd like to attach its own information to a label has to inherit from this class and has to add its own information as fields of this new class.

Identification:

An attribute can be identified by its ID. Every attributes used with the same meaning (for example: Integer, String, Topology...) have the same worldwide unique ID.

Addition:

An attribute can be added to a label only if there is no attribute yet with the same ID. Call-back methods are offered, called automatically before and after the addition action.

Removal:

An attribute can be removed from a label only if there is an attribute yet with the same ID. Call-back methods are offered, called automatically before and after the removal action. A removed attribute cannot be found again. After a removal, only an addition of an attribute with the sane ID is possible (no backup...).

Modification & Transaction:

An attribute can be backuped before a modification. Only one backup attribute by transaction is possible. The modification can be forgotten (abort transaction) or validated (commit transaction).

BackupCopy and restore are methods used by the backup or abort transaction actions. BackupCopy is called by Backup to generate an attribute with the same contents as the current one. Restore is called when aborting a transaction to transfer the backuped contents into the current attribute. These methods must be implemented by end use inheriting classes.

A standard implementation of BackupCopy is provided, but it is not necessary a good one for any use.

Copy use methods:

Paste and NewEmpty methods are used by the copy algorithms. The goal of "Paste" is to transfer an attribute new contents into another attribute. The goal of "NewEmpty" is to create an attribute without contents, to be further filled with the new contents of another one. These 2 methods must be implemented by end use inheriting classes.

AttributeDelta:

An AttributeDelta is the difference between to attribute values states. These methods must be implemented by end use inheriting classes, to profit from the delta services.

ShortCut Methods concerning associated attributes

◆ IsNew()

Standard_Boolean TDF_Attribute::IsNew ( ) const

Returns true if the attribute has no backup.

◆ IsValid()

Standard_Boolean TDF_Attribute::IsValid ( ) const

Returns true if the attribute is valid; i.e. not a backuped or removed one.

◆ Label()

const TDF_Label TDF_Attribute::Label ( ) const

Returns the label to which the attribute is attached. If the label is not included in a DF, the label is null. See Label. Warning If the label is not included in a data framework, it is null. This function should not be redefined inline.

◆ NewEmpty()

virtual Handle< TDF_Attribute > TDF_Attribute::NewEmpty ( ) const
pure virtual

◆ operator<<()

Standard_OStream& TDF_Attribute::operator<< ( Standard_OStream anOS) const
inline

◆ Paste()

virtual void TDF_Attribute::Paste ( const Handle< TDF_Attribute > &  intoAttribute,
const Handle< TDF_RelocationTable > &  aRelocationTable 
) const
pure virtual

This method is different from the "Copy" one, because it is used when copying an attribute from a source structure into a target structure. This method may paste the contents of <me> into <intoAttribute>.

The given pasted attribute can be full or empty of its contents. But don't make a NEW! Just set the contents!

It is possible to use <aRelocationTable> to get/set the relocation value of a source attribute.
