SAP CL_FDT_EXPRESSION OO Class - FDT: Abstract Expression Class
CL_FDT_EXPRESSION is a standard SAP object class available within R/3 SAP systems depending on your version and release level. You can view/maintain the class details by entering its name into the relevant SAP transactions such as SE24, SE80 or even SE84. Below is the documentation available for class CL_FDT_EXPRESSION including details of:
- Interface class implementations
- Inheritance details
- Methods defined within class ( including link to full details )
- Attributes ( including initial values )
- Class Events
Inheritance
This OO class has a superclass assigned to it, which means it will inherit its objects and methods. The superclass for CL_FDT_EXPRESSION is CL_FDT_MAINTENANCEInterface Implementation
This OO class is an Interface Implementation, which means it will implement its own version of the methods from implementation class IF_FDT_EXPRESSIONMethod list of CL_FDT_EXPRESSION 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...
