Detailed Description

base class for objects handled by QEvent and QGlobalDataManager.

Author: Marco Vignati

Every object that is going to be handled by QEvent or QGlobalDataManager must inherit from QObject. This class only contains the validity flag (that says if the object has been assigned a value) and the write flag (that sets wheter the QObject added to a QEvent should be written in the output files or not). Base types that inherit from this class are QInt, QDouble, QFloat (templates implementations of QBaseType), QBool and QString. To store a root TObject use QTObject. Specicic QObject(s) can be found in pkg/dianadata or in the QObjects groups of this documentation.

Inheriting classes must declare the macro QObjectDef in the .hh file, that contains the declaration of the Fill() and Duplicate() functions. The .cc file must contain the declaration of the macro QObjectImp, that implements the two functions. The .cc existence is not mandatory (a QObject can be a simple data container, so the .cc is useless, QBaselineData for example has no cc), Makefiles will automatically generate a .cc with the needed declaration of QObjectImp.

Inheriting classes must implement the Clear method, and optionally can implement the methods Dump (that is called to print the object, e.g. cout<<object), WriteOnStream and ReadOnStream (to perform I/O with text files). If the two latter methods are not implemented, the default I/O, implemented in QObjectInspector, is used.

◆ anonymous enum

anonymous enum

TObject bits.

Enumerator
kIsValid	object has been assigned a value
kWrite	write this object onto output files, this and the bits below should go in the handle? no because of efficiency. They are stored in the fTemporaryBits member
kIsRequired	this object has been requested by somebody
kIsJustAdded	this object has been just added to the event
