Method list of CL_ABAP_DBFEATURES SAP class
A method is a coding block that performs a certain procedure (i.e. ABAP functionality) on an object within the overall SAP class. In simple terms if the object is an SAP database table a method could be the procedure to add a record or to delete a record. If you are new to OO in many respects, the implementation of a method is similar to a function module and can be called in a very similar way using CALL METHOD.
Instead of "CALL FUNCTION", Methods are referenced using the following syntax: CALL METHOD =>methodname EXPORTING/IMPORTING...
