  - CsvMapReader
```
public CsvMapReader(Reader reader,
                    CsvPreference preferences)
```
    Constructs a new CsvMapReader with the supplied Reader and CSV preferences. Note that the reader will be wrapped in a BufferedReader before accessed.
    
    Parameters:
    
    reader - the reader
    
    preferences - the CSV preferences
    
    Throws:
    
    NullPointerException - if reader or preferences are null
  - CsvMapReader
```
public CsvMapReader(ITokenizer tokenizer,
                    CsvPreference preferences)
```
    Constructs a new CsvMapReader with the supplied (custom) Tokenizer and CSV preferences. The tokenizer should be set up with the Reader (CSV input) and CsvPreference beforehand.
    
    Parameters:
    
    tokenizer - the tokenizer
    
    preferences - the CSV preferences
    
    Throws:
    
    NullPointerException - if tokenizer or preferences are null
- Method Detail
  - read
```
public Map<String,String> read(String... nameMapping)
                        throws IOException
```
    Reads a row of a CSV file into a Map, using the supplied name mapping to map column values to the appropriate map entries.
    
    Specified by:
    
    read in interface ICsvMapReader
    
    Parameters:
    
    nameMapping - an array of Strings linking the CSV columns to their corresponding entry in the Map (the array length should match the number of columns). A null entry in the array indicates that the column should be ignored (e.g. not added to the Map).
    
    Returns:
    
    a Map of column names to column values (Strings, as no processing is performed), or null if EOF
    
    Throws:
    
    IOException - if an I/O error occurred
  - read
```
public Map<String,Object> read(String[] nameMapping,
                               CellProcessor[] processors)
                        throws IOException
```
    Reads a row of a CSV file into a Map, using the supplied name mapping to map column values to the appropriate map entries, and the supplied processors to process the values before adding them to the Map.
    
    Specified by:
    
    read in interface ICsvMapReader
    
    Parameters:
    
    nameMapping - an array of Strings linking the CSV columns to their corresponding entry in the Map (the array length should match the number of columns). A null entry in the array indicates that the column should be ignored (e.g. not added to the Map).
    
    processors - an array of CellProcessors used to further process data before it is added to the Map (each element in the processors array corresponds with a CSV column - the number of processors should match the number of columns). A null entry indicates no further processing is required (the unprocessed String value will added to the Map).
    
    Returns:
    
    a Map of column names to column values, or null if EOF
    
    Throws:
    
    IOException - if an I/O error occurred
