Rows of data

A row in PDI is comprised of one RowMetaInterface class to describe the row.  The row metadata contains everything you need to know about the rows like the names of the fields, the data types, the lengths, descriptions and much more.  The row also contains 0, 1 or more rows of data in the form of a simple Object[]: array of java.lang.Object where each value contains either null or one of the data types listed in the available data types section.
