public int getRowCount()
DataModel
Return the number of rows of data available.
If the number of rows of data available is not known then -1 is returned. This may happen for DataModels that wrap sources of data such as java.sql.ResultSet that provide an iterator to access the "next item" rather than a fixed-size collection of data.
