`static String`	`DEFAULT_BUNDLE_NAME` The name of the resource bundle for translations of error messages in opencsv.
`static char`	`DEFAULT_ESCAPE_CHARACTER` The default escape character to use if none is supplied to the constructor.
`static boolean`	`DEFAULT_IGNORE_LEADING_WHITESPACE` The default leading whitespace behavior to use if none is supplied to the constructor.
`static boolean`	`DEFAULT_IGNORE_QUOTATIONS` If the quote character is set to null then there is no quote character.

`static boolean`	`DEFAULT_STRICT_QUOTES` The default strict quote behavior to use if none is supplied to the constructor.
`static int`	`INITIAL_READ_SIZE` The average size of a line read by opencsv (used for setting the size of StringBuilders).

  - parseLineMulti
```
String[] parseLineMulti(String nextLine)
                 throws IOException
```
    Parses an incoming String and returns an array of elements. This method is used when the data spans multiple lines.
    
    Parameters:
    
    nextLine - Current line to be processed
    
    Returns:
    
    The comma-tokenized list of elements, or null if nextLine is null
    
    Throws:
    
    IOException - If bad things happen during the read
  - parseLine
```
String[] parseLine(String nextLine)
            throws IOException
```
    Parses an incoming String and returns an array of elements. This method is used when all data is contained in a single line.
    
    Parameters:
    
    nextLine - Line to be parsed.
    
    Returns:
    
    The list of elements, or null if nextLine is null
    
    Throws:
    
    IOException - If bad things happen during the read
  - parseToLine
```
String parseToLine(String[] values,
                   boolean applyQuotesToAll)
```
    Essentially a "Reverse parse" where an array of values are concatenating to a csv delimited string. NOTE: as of the 4.1 release this functionality is not considered production ready and has not been fully tested (and the ability to add a parser to the CSVWriter has not been implemented yet. I am adding this now because because I need to do the 4.1 release because of the number of defect fixes and I do not want to strip this out.
    
    Parameters:
    
    values - List of elements to parse.
    
    applyQuotesToAll - - If true all strings in the array will have quotes if it needs it or not. If false then it will only have quotes if it needs it (i.e. contains a quote character).
    
    Returns:
    
    CSV formatted string representing the values in the array.
    
    Since:
    
    4.1
  - nullFieldIndicator
```
CSVReaderNullFieldIndicator nullFieldIndicator()
```
    Returns:
    
    The null field indicator.
  - getPendingText
```
String getPendingText()
```
    If a parser is in the middle of parsing a multiline field, this will return the text collected so far.
    
    Returns:
    
    The incomplete text for a multiline field. If there is no pending text, this returns an empty string.
    
    Since:
    
    4.1
  - setErrorLocale
```
void setErrorLocale(Locale errorLocale)
```
    Sets the locale for all error messages.
    
    Parameters:
    
    errorLocale - Locale for error messages. If null, the default locale is used.
    
    Since:
    
    4.2
