Therefore Programming Interface 3.0

1

Connect to the Thereforeâ„¢ server (see "Server - Connect and Disconnect" for Details)

2

Declare and initialize a new TheDocument instance.

3

Retrieve the document from the server.

4

Get the document's IndexData.

5

Iterate and print the index data.

5A. Iterate {string fieldname, object value} pairs.

or 5B. Iterate field names only.

or 5C. Iterate values only.

Requirements and Assumptions:

Document number 42 exists in your Thereforeâ„¢ system.

If these assumptions do not apply to your system or configuration please replace them with appropriate values when copying the code samples below.
