RecordFormat class

The RecordFormat class allows the Java™ program to describe a group of fields or parameters. A record object contains data described by a RecordFormat object. If the program is using record-level access classes, the RecordFormat class also allows the program to specify descriptions for key fields.

RecordFormat

A RecordFormat object contains a set of field descriptions. The field description can be accessed by index or by name. Methods exist on the RecordFormat class to do the following:

Add field descriptions to the record format.
Add key field descriptions to the record format.
Retrieve field descriptions from the record format by index or by name.
Retrieve key field descriptions from the record format by index or by name.
Retrieve the names of the fields that make up the record format.
Retrieve the names of the key fields that make up the record format.
Retrieve the number of fields in the record format.
Retrieve the number of key fields in the record format.
Create a Record object based on this record format.

Example: Adding field descriptions to a record format

The following example adds the field descriptions created in the field description example to a record format:

     // Create a record format object, then fill it with field descriptions.
     RecordFormat rf = new RecordFormat();
     rf.addFieldDescription(bfd);
     rf.addFieldDescription(cfd1);
     rf.addFieldDescription(cfd2);
