Method Detail

createDataRow

public static ReportDataRow createDataRow(ReportDataFactory dataFactory,
                                          java.lang.String query,
                                          DataSet parameters)
                                   throws DataSourceException,
                                          ReportDataFactoryException
Throws:
DataSourceException
ReportDataFactoryException

get

public java.lang.Object get(int col)
                     throws DataSourceException
Returns the value of the expression or column in the tablemodel using the given column number as index. For functions and expressions, the getValue() method is called and for columns from the tablemodel the tablemodel method getValueAt(row, column) gets called.

Specified by:
get in interface DataRow
Specified by:
get in interface DataSet
Parameters:
col - the item index.
Returns:
the value.
Throws:
java.lang.IllegalStateException - if the datarow detected a deadlock.
DataSourceException - if an error occured.

get

public java.lang.Object get(java.lang.String col)
                     throws DataSourceException
Returns the value of the function, expression or column using its specific name. The given name is translated into a valid column number and the the column is queried. For functions and expressions, the getValue() method is called and for columns from the tablemodel the tablemodel method getValueAt(row, column) gets called.

Specified by:
get in interface DataRow
Parameters:
col - the item index.
Returns:
the value.
Throws:
java.lang.IllegalStateException - if the datarow detected a deadlock.
DataSourceException - if an error occured.

getColumnName

public java.lang.String getColumnName(int col)
Returns the name of the column, expression or function. For columns from the tablemodel, the tablemodels getColumnName method is called. For functions, expressions and report properties the assigned name is returned.

Specified by:
getColumnName in interface DataRow
Specified by:
getColumnName in interface DataSet
Parameters:
col - the item index.
Returns:
the name.

getColumnCount

public int getColumnCount()
Returns the number of columns, expressions and functions and marked ReportProperties in the report.

Specified by:
getColumnCount in interface DataRow
Specified by:
getColumnCount in interface DataSet
Returns:
the item count.
