object created dynamically. how to call a method or interface from it

Former Member — Wed, 25 May 2011 13:27:45 GMT

Hi Experts,

I've just created an abap proxy dynamically

FIELD-SYMBOLS <ref> TYPE any.

CREATE DATA dref TYPE REF TO

(ld_class).

ASSIGN dref->* TO <ref>.

CREATE OBJECT <ref>

TYPE

(ld_class)

EXPORTING

logical_port_name =logicalport.

This runs OK

But I can't call an Interface of the object proxy that belongs to ld_class

ld_prot ?= <ref>->if_proxy_basis~get_protocol( if_wsprotocol=>sequence ).

because the object <ref> is type any, it doesen't runs

This work' s fine

MOVE <ref> ?TO proxy1.

ld_prot ?= proxy->if_proxy_basis~get_protocol( if_wsprotocol=>sequence )

if proxy is explicity declarated like class proxy

But I don't want do it. I want do it dynamically to avoid write data declaration explicity

I think this is a problem for every data that must be declarated by the form TYPE REF TO

What must I do ?

thanks in advance.

Get the name of the method into a string - l_method, say. Then use: CALL METHOD <ref>->(l_method) EXPORTING... I'm not sure you need to use a field symbol though - consider this:

DATA: lr_proxy TYPE REF TO OBJECT, "Maybe CL_PROXY_BASIS instead of OBJECT???
      l_method TYPE string.

CREATE OBJECT lr_proxy TYPE (ld_class).
CALL METHOD lr_proxy->(l_method) EXPORTING.
