Method Detail

getName

public String getName()

getFormula

public String getFormula()

convert

public static FormulaParameter[] convert(org.pentaho.reporting.engine.classic.core.ParameterMapping[] definedVariableNames)

Maps the legacy parameter mapping into the new formula based system. ParameterMapping#getName returns the report's datarow-column name (source) and ParameterMapping#getAlias returns the target parameter in the transformation.

Parameters:

definedVariableNames -

Returns:

create

public static FormulaParameter create(String reportFieldName,
                                      String transformationParameterName)

convert
