Chapter 5. Adapter Class Reference 61
Generation example
The object method corresponding to instance method getTime() of the java.util.Date
class is generated as shown below:
METHOD-ID. JM-GETTIME AS "getTime". [1]
...
LINKAGE SECTION.
01 RTN-VALUE PIC S9(18) COMP-5.
PROCEDURE DIVISION RETURNING RTN-VALUE.
...
END METHOD JM-GETTIME.
1. Since there is only one method with name "getTime," a method with name
"getTime" is generated with no number assigned.
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.
java-lang-String class
Like other classes, the java.lang.String class is mapped to the java-lang-String class.
However, the java-lang-String class has the following methods for referencing or
setting character string data, in addition to the methods defined in the
java.lang.String class:
Method name Type Function
NEW-STRING-X Factory Generates a String object having the specified
alphanumeric data item as the initial value.
NEW-STRING-N Factory Generates a String object having the specified
national data item as the initial value.
GET-STRING-X Object Fetches the character string as an alphanumeric data
item.
GET-STRING-N Object Fetches the character string as a national data item.
GET-STRING-LENGTH-X Object Determines alphanumeric data item length.
GET-STRING-LENGTH-N Object Determines national data item length.
