ExpressionDataRow
final public class ExpressionDataRow implements DataRow(Code)
A datarow for all expressions encountered in the report. This datarow is a stack-like structure, which allows easy adding and removing of expressions, even if these expressions have been cloned and or otherwisely modified.

Constructor Detail
ExpressionDataRow
public ExpressionDataRow(GlobalMasterRow masterRow, ReportContext reportContext, int capacity)(Code)




Method Detail
advance
public ExpressionDataRow advance(GlobalMasterRow master, boolean deepTraversing) throws DataSourceException(Code)
Advances to the next row and attaches the given master row to the objects contained in that client data row.
Parameters:
  master -
Parameters:
  deepTraversing - only advance expressions that have been marked asdeeply traversing



derive
public ExpressionDataRow derive(GlobalMasterRow master) throws DataSourceException(Code)



get
public Object get(int col) throws DataSourceException(Code)
Returns the value of the expressions 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.
Parameters:
  col - the item index. the value.
throws:
  IllegalStateException - if the datarow detected a deadlock.



get
public Object get(String col) throws DataSourceException(Code)
Returns the value of the function, expressions 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.
Parameters:
  col - the item index. the value.
throws:
  IllegalStateException - if the datarow detected a deadlock.



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



getColumnName
public String getColumnName(int col)(Code)
Returns the name of the column, expressions or function. For columns from the tablemodel, the tablemodels getColumnName method is called. For functions, expressions and report properties the assigned name is returned.
Parameters:
  col - the item index. the name.



getFlags
public DataFlags getFlags(String col)(Code)



getFlags
public DataFlags getFlags(int col)(Code)



getSlots
public ExpressionSlot[] getSlots()(Code)



popExpression
public synchronized void popExpression() throws DataSourceException(Code)



popExpressions
public synchronized void popExpressions(int counter) throws DataSourceException(Code)



pushExpression
public synchronized void pushExpression(ExpressionSlot expressionSlot) throws DataSourceException(Code)
This adds the expression to the data-row and queries the expression for the first time.
Parameters:
  ex -
Parameters:
  rd -
throws:
  DataSourceException -



pushExpressions
public synchronized void pushExpressions(ExpressionSlot[] expressionSlots) throws DataSourceException(Code)
