Class StrTokenizer

  • All Implemented Interfaces:

    @Deprecated
public class StrTokenizer
extends java.lang.Object
implements java.util.ListIterator<java.lang.String>, java.lang.Cloneable
    Deprecated.
    as of 3.6, use commons-text StringTokenizer instead
    Tokenizes a string based on delimiters (separators) and supporting quoting and ignored character concepts.

    This class can split a String into many smaller strings. It aims to do a similar job to StringTokenizer, however it offers much more control and flexibility including implementing the ListIterator interface. By default, it is set up like StringTokenizer.

    The input String is split into a number of tokens. Each token is separated from the next String by a delimiter. One or more delimiter characters must be specified.

    Each token may be surrounded by quotes. The quote matcher specifies the quote character(s). A quote may be escaped within a quoted section by duplicating itself.

    Between each token and the delimiter are potentially characters that need trimming. The trimmer matcher specifies these characters. One usage might be to trim whitespace characters.

    At any point outside the quotes there might potentially be invalid characters. The ignored matcher specifies these characters to be removed. One usage might be to remove new line characters.

    Empty tokens may be removed or returned as null. 

     "a,b,c"         - Three tokens "a","b","c"   (comma delimiter)
 " a, b , c "    - Three tokens "a","b","c"   (default CSV processing trims whitespace)
 "a, ", b ,", c" - Three tokens "a, " , " b ", ", c" (quoted text untouched)

      • tokenize

        protected java.util.List<java.lang.String> tokenize​(char[] srcChars,
                                                    int offset,
                                                    int count)
        Deprecated.
        Internal method to performs the tokenization.

        Most users of this class do not need to call this method. This method will be called automatically by other (public) methods when required.

        This method exists to allow subclasses to add code before or after the tokenization. For example, a subclass could alter the character array, offset or count to be parsed, or call the tokenizer multiple times on multiple strings. It is also be possible to filter the results.

        StrTokenizer will always pass a zero offset and a count equal to the length of the array to this method, however a subclass may pass other values, or even an entirely different array.

        Parameters:
        srcChars - the character array being tokenized, may be null
        offset - the start position within the character array, must be valid
        count - the number of characters to tokenize, must be valid
        Returns:
        the modifiable list of String tokens, unmodifiable if null array or zero count
