Interface PObjResultSet

All Known Implementing Classes:

JdbcQuery.PObjJdbcResultSet

public interface PObjResultSet

A result set provides an interface to process the results of a Query row by row.

It maintains a cursor pointing to its current row of data. Initially the cursor is positioned before the first row. The next() method moves the cursor to the next row, and because it returns false when there are no more rows in the result set, it can be used in a while loop to iterate through the result set.
