org.jfree.report.data.StaticDataRow
- DataRow, DataSet
This is a static datarow holding a value for each name in the datarow. This
datarow does not hold dataflags and thus does not track the changes done to
the data inside.
The StaticDataRow is a derived view and is used to provide a safe collection
of the values of the previous datarow.
Object | get(String col) - Returns the value of the function, expression or column using its specific
name.
|
Object | get(int col) - Returns the value of the expression or column in the tablemodel using the
given column number as index.
|
int | getColumnCount() - Returns the number of columns, expressions and functions and marked
ReportProperties in the report.
|
String | getColumnName(int col) - Returns the name of the column, expression or function.
|
DataFlags | getFlags(String col) - Queries lowlevel meta-data for the current value of the specified column.
|
DataFlags | getFlags(int col) - Queries lowlevel meta-data for the current value of the specified column.
