Constructor Detail


public JeksParameter(JeksExpressionSyntax syntax,
                     Interpreter interpreter,
                     javax.swing.table.TableModel tableModel)
Creates a JeksParameter.
syntax - expression syntax used to get the syntax of cells and create the key of a cell or of a cell set.
interpreter - the interpreter used to compute the value of a cell.
tableModel - the table model used to get a stored value for a given cell key.
Method Detail


public java.lang.Object getParameterKey(java.lang.String parameter)
Returns the key matching parameter or null. For a valid parameter, it returns the matching JeksCell instance if parameter is a cell or the matching JeksCellSet instance if parameter is a cell set or IllegalCellException.class if parameter is an illegal cell identifier (#REF!).
Specified by:
getParameterKey in interface ExpressionParameter
Following copied from interface: com.eteks.parser.ExpressionParameter
parameter - the identifier of a parameter. The identifier is already valid for the isValidIdentifier () method of the syntax used by the parser.
null if parameter is not valid. Otherwise the key returned will be the one passed to getParameterValue () at run time. The key may be the parameter itself.


public java.lang.Object getParameterValue(java.lang.Object parameterKey)
Returns the value of the parameter matching parameterKey. If parameterKey is an instance of JeksCell it returns the value of the cell, if parameterKey is an instance of JeksCellSet it returns the values of the cell set in an Object [][] array, and if parameterKey is IllegalCellException.class it throws an exception of IllegalCellException class.
Specified by:
getParameterValue in interface ExpressionParameter
parameterKey - a key returned by the getParameterKey () method.
IllegalCellException - if parameterKey is IllegalCellException.class meaning the cell is invalid.
