    public static final TokenExtractor.IDelimiterFinder DF_CommonFullSymbolChars

    Delimiter= any character that is generally not legal in a symbol name, in particular:

  • any character allowed in java identifier
  • additional '/' character for java signature
  • additional '+' character for native relative signature

    • public static final TokenExtractor.IDelimiterFinder DF_CommonSymbolChars

    Public Constructors

    public TokenExtractor (TokenExtractor.IDelimiterFinder delimiterFinder)

    Create a token extractor.

    Parameters
    delimiterFinder a delimiter finder; client code may either create their own or use one of the standard finders, see DF_*

    Public Methods

    public String extract (String s, int o)

    Extract the token spanning over the provided offset of the input string.

    Parameters
    s input string
    o start offset
    Returns
    • the token as a substring of s or null if not found.

    public int[] extractCoordinates (String s, int o)

    Extract the token spanning over the provided offset of the input string.

    Parameters
    s input string
    o start offset
    Returns
    • an array with 2 indexes [start, end] of the token, or null if not found.

    public static List<TokenExtractor> getGenericTokenList ()

    Retrieve the generic list of Token Extractor, based on DF_* TokenExtractor.IDelimiterFinder. List is sorted from least to most restrictive.

    Returns
    • token extractor list

    Protected Methods

    protected boolean match (String s, int index)
