58 Chapter 5. Adapter Class Reference
Generation example
The factory method corresponding to class method abs (long) of the java.lang.Math
class is generated as shown below:
METHOD-ID. JM-ABS-01 AS "abs-01". [1]
...
LINKAGE SECTION.
01 RTN-VALUE PIC S9(18) COMP-5.
01 PARA-1 PIC S9(18) COMP-5.
PROCEDURE DIVISION USING PARA-1 RETURNING RTN-VALUE.
...
END METHOD JM-ABS-01.
1. Since more than one "abs" method is declared, a method with name "abs-01" is
generated for abs (long) that is declared second.
Supplement
When a COBOL method name is generated from a Java method name, a number is
assigned to secure the uniqueness of the name. The class browser or method name
cross-reference list file can be used to check the correspondence between Java
methods and COBOL methods. In the case of class browser, it can be identified
from the parameter that appears during method selection. In the case of method
name cross-reference list file, it can be identified from the type of argument of the
constructor.
