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. author:    Thomas Morgner Constructor Summary public   ExpressionDataRow(GlobalMasterRow masterRow, ReportContext reportContext, int capacity)      Method Summary public  ExpressionDataRow advance(GlobalMasterRow master, boolean deepTraversing)      Advances to the next row and attaches the given master row to the objects contained in that client data row. public  ExpressionDataRow derive(GlobalMasterRow master)      public  Object get(int col)      Returns the value of the expressions or column in the tablemodel using the given column number as index. public  Object get(String col)      Returns the value of the function, expressions or column using its specific name. public  int getColumnCount()      Returns the number of columns, expressions and functions and marked ReportProperties in the report. public  String getColumnName(int col)      Returns the name of the column, expressions or function. public  DataFlags getFlags(String col)      public  DataFlags getFlags(int col)      public  ExpressionSlot[] getSlots()      public synchronized  void popExpression()      public synchronized  void popExpressions(int counter)      public synchronized  void pushExpression(ExpressionSlot expressionSlot)      This adds the expression to the data-row and queries the expression for the first time. public synchronized  void pushExpressions(ExpressionSlot[] expressionSlots)      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.
