Every shape or group has a name. However, the name is only relevant when working with Visual Basic. Names are not used or accessed in the actual PowerPoint product. If a name has not been set, then PowerPoint assigns one automatically. However this name is not reliable as it may change when shapes are cut and pasted. Therefore you should explicitly assign a name, if you want to use it later on.

To get the object name use:

java.lang.String getName()

To set the object name use:

void setName(java.lang.String name)
