Class FixedRecordGenerator

java.lang.Object

com.claritysys.util.FixedRecordGenerator

public class FixedRecordGenerator
extends java.lang.Object

Generates a JavaBean for parsing/encoding fixed-width format records, such as are used in legacy systems.

Run from command line, it takes as parameters:

1. The path to an input file, which describes the record format.
2. The name of the Java file to write out.

The input file has one line describing each field in the record format. Each line is composed of comma-separated values, as follows:

• The formal field name. Different from JavaBean field name because often illegal names are used. This gets written into a comment, to assist in tying fields back to the 'spec' format.
• Field description -- remember, no commas! (Because each of these fields is already comma separated).
• Field type and size, such as A25, D8, N12. All the generated fields will be of type String anyway, but the size is critical to parse the record correctly.
• Field name, as to be written in generated JavaBean.
