Creating a PL/SQL-Block with Boolean-Return and Check

Question

Hello folks,
I have some kind of tricky problem. Actually, I want to integrate a small Task-System on my Apex 2.2 installation. Every task is intended to have a field with a anonymous PL/SQL-block in the shape of:
Declare
Begin
return true/false;
End;
It is comparable to the condition-PL/SQL-block you can set for almost ev'ry item.
It's not the problem to write this block half-automated, but how do I check it? Is there any kind of Database-Function?
Thanks for your replies.
Matthias.

I believe Struct is basically used for SQL types , and your 'T_NACHRICHT' is a type of Objects so please pass the objects array to STRUCT.
For example if type is :
CREATE OR REPLACE TYPE T_NACHRICHT AS OBJECT
ID_Nachricht NUMBER,
ID_Vorgang NUMBER,
--datum                 TIMESTAMP(6),
Betreff VARCHAR2(400),
-- Nachricht CLOB,
ID_Antwort NUMBER,
ist_neu VARCHAR2(5),
CONSTRUCTOR FUNCTION T_NACHRICHT(
p_ID_Vorgang NUMBER,
p_Betreff VARCHAR2) RETURN SELF AS RESULT
then call the struct in below way:
STRUCT nachrichtSTRUCT = null;
StructDescriptor structDesc = StructDescriptor.createDescriptor("T_NACHRICHT", conn);
          Object [] obj = {123456,123456,"ABC",123456,"ABCD"};
nachrichtSTRUCT = new STRUCT(structDesc, conn, obj);
