Chapter 5. Adapter Class Reference 59
- If a same property name has already been assigned, the second and
subsequent property names are each suffixed with a hyphen "-" followed by
a two-digit number (01 to 99) to prevent name duplication. (See
"
Numbering names.
")
- A name exceeding 30 characters is truncated after the 30th character.
3. When FINAL is specified, no property method with the SET specification is
generated.
4. The property value is a parameter used to transfer a property value. The data
description entry expands the COBOL description entry corresponding to the Java
field attribute. See "
Data types
" for the correspondence of data types.
Generation rules
The property method corresponding to the instance variable nval of the
java.io.StreamTokenizer class is generated as shown below:
METHOD-ID. GET PROPERTY JF-NVAL. [1]
...
LINKAGE SECTION.
01 GET-VALUE COMP-2. [2]
PROCEDURE DIVISION RETURNING GET-VALUE.
...
END METHOD JF-NVAL.
METHOD-ID. SET PROPERTY JF-NVAL. [3]
...
LINKAGE SECTION.
01 SET-VALUE COMP-2.
PROCEDURE DIVISION USING SET-VALUE.
...
END METHOD JF-NVAL.
1. The property name is generated by adding "NVAL", which is the uppercase of
the Java field name, to "JF-".
2. "nval" is mapped to COMP-2 because its attribute is double.
3. Since FINAL is not specified, a property method with the SET specification is also
generated.
Supplement
When a property name is generated from a field name, a number is assigned to
secure the uniqueness of the name. The class browser can be used to check the
correspondence between fields and properties.
