2.3 Table Data

The actual data values in a table are considered to be a sequence of rows, each containing one value for each of the table's columns. As explained above, each such value is an Object, and information about its class (as well as semantic metadata) is available from the column's ColumnInfo object.

StarTables come in two flavours, random-access and sequential-only; you can tell which one a given table is by using its isRandom method, and how its data can be accessed is determined by this. In either case, most of the data access methods are declared to throw an IOException to signal any data access error.
