ColumnMapping

public ColumnMapping(String[] pColumnNames,
                     String[] pReferencedColumnNames)

Constructs the ColumnMapping with the different column names and referenced column names. If the referenced column names are null, the are automatically mapped to the same name as the column names.

Parameters:

pColumnNames - source column names of the ColumnMapping.

pReferencedColumnNames - referenced column names of the ColumnMapping.

Returns:

the referenced column names of the ReferenceDefinition.

getReferencedColumnName

public String getReferencedColumnName(String pColumnName)

Gets the corresponding referenced column name to the given column name.

Parameters:

pColumnName - the column name.
