creating same instance again

Former Member — Thu, 24 Apr 2014 16:16:10 GMT

Hi ,

I have the following code.

DATA: r_plane TYPE REF TO lcl_airplane,

CREATE OBJECT r_plane EXPORTING im_name = 'LH Berlin'

im_planetype = 'A321'.

CREATE OBJECT r_plane EXPORTING im_name = 'LH Frankfurt'

im_planetype = '747-400'.

Here both the object instance name is r_plane ...Does this mean that ABAP will internally create two objects with the same reference "r_plane"

Or will it just overwrite the existing instance.

Hi,

One of the nicest thing about this profession is that we can try things without killing any one in the process....

Do a test....

After second instance creation, first one will enter zombie/limbo state. It will exist for a while, without having any way to interact with us because of lack of reference, and finally it will be gobbled up by the garbage collector.

Hi Hema,

ABAP will overwrite the first reference with the second reference in r_plane, since you are using the same reference Variable. ie., r_plane contains reference to new parameters of LH-FRANKFRUT and planetype 747-400.

Old reference gets overwirted.
