IndexedRecord stereotype

Use a structured record that is specialized with the indexedRecord stereotype to access an indexed file.

This type of file uses an index to associate the value of a designated field in the record with the logical position of that record in the file.

An indexed record can be either a fixed-length or a variable-length record. If it is a variable-length record, you must define the record at its maximum size and specify either the lengthItem property, or the numElementsItem property, or both (see IndexedRecord properties). You can use EGL statements to accomplish the following tasks:

At generation time, use a ResourceAssociation part to specify how you want an indexed record to be implemented for your target platform and to provide information about how the fileName property relates to a physical file. For more information, see the EGL Generation Guide.

For information about properties you can assign to an IndexedRecord definition, see IndexedRecord properties.
