throw

Throw anything as exception

Throw any object as exception in a minimalistic way. The prototype for this class is native javascript throw.

Here is the idea

we should be able to do something like:

throw( 'Something bad happened' )

or even

message e001(zmy_message_class) with 'this` 'and' 'that' into data(lv_dummy).
throw( ).

In both cases we expect a static exception should be raised with a text message from a given text or just inherited from a system message. That's it.

Usage

Via static method

zcl_throw=>from( 'Error happenned' ).

or

message e001(zmy_message_class) with 'this` 'and' 'that' into data(lv_dummy).
zcl_throw=>from( ).

Via instance

Not sure if we even need this way, may be for extensions with inherited classes

new zcl_throw( )->throw( 'Error happenned' ).

or

message e001(zmy_message_class) with 'this` 'and' 'that' into data(lv_dummy).
new zcl_throw( )->throw( ).

Via interface

You can also implement ZIF_THROW interface in your class or just inherit from ZCL_THROW class

In short here is the pattern how you can use it:

class zcl_your_class definition.
  public section.
    interfaces zif_throw.    
  private section.
    aliases throw for zif_throw~throw.
    methods do_something raising cx_static_check.
endclass.
class zcl_your_class implementation.
  method zif_throw~throw.
    zcl_throw=>from( object ).
  endmethod.
  method do_something.
    if something_bad_happened( ).
      throw( 'Something bad happened' ).
    endif.
  endmethod.
endclass.
