Appendix C. Class Definition Statement File Reference

A class definition statement (CDS) file specifies SELECT, FETCH, and MAP

statements for all event classes supported by adapters that utilize a CDS file. This

provided file is required for most adapters and has the same format for all

adapters that use it. A CDS file has an extension of .cds; see each adapter chapter

for exact file names.

Most of the CDS file is composed of class definition statements. A CDS file has the

following format:

Comment lines begin with a number sign (#). For syntax reference information in

BNF notation, see "Class Definition Statement File Syntax Diagrams" on page 161.

Various operators are used in class definition statements, as follows:

v The PREFIX and SUFFIX operators are valid only for string attribute names,

v The CONTAINS operator is valid only on string values.

v The not equals (!=), greater than (>), greater than or equals (>=), less than (<),

The following is an example of the use of the operators. In this example, the code

is for an AS/400 message adapter:

map_default_clause

class_name

select_clause

fetch_clause

map_clause

values, or keys.

and less than or equals (<=) operators are applicable only to integer values; they

are not implemented for integer keys.
