Retrieving a List of All Classes Implementing an Interface

The standard abstraction provided by the XCO library for ABAP interfaces (IF_XCO_AO_INTERFACE) can be used to retrieve a list of all implementations of a given interface:

Sample Code:

DATA(lo_interface) = xco_cp_abap=>interface( 'ZMY_INTERFACE' ).
 
" From an interface handle (in this case LO_INTERFACE) we can easily obtain
" access to its implementations via the IMPLEMENTATIONS data member. Obtaining
" a list of all implementations for an interface can be accomplished like this:
DATA(lt_implementations) = lo_interface->implementations->all->get( ).
 
" Once the previous statement has been executed, LT_IMPLEMENTATIONS will be a
" table of IF_XCO_AO_CLASS objects which can then subsequently be used to e.g.
" read the content of each class. Note that only those implementations will be
" considered which are either C1-released or part of a customer software component.
" Additionally, if only the names of the classes implementing the interface
" shall be obtained the following statement can be used:
DATA(lt_implementation_names) = lo_interface->implementations->all->get_names( ).
