      public StreamParser(String string, String charset)
      Creates a new instance of StreamParser which will read the contents of the supplied String

    • StreamParser

      public StreamParser(Reader reader, String charset)
      Creates a new instance of StreamParser which will read the contents of the supplied Reader (the reader should handle the encoding charset)

  • Method Details

    • getCharset

      public String getCharset()

    • setParseRule

      public void setParseRule(int type, int length)
      Sets the parse rule and the length of the element to be parsed. This will be called only for Fixed Length files
      Parameters:
      type - should be StreamParser.FIXED_LENGTH
      length - the number of characters to be read

    • setParseRule

      public void setParseRule(int type, char sep)
      sets the parse rule and separator character of the element to be parsed. This is only called for simple Separated files
      Parameters:
      type - should be StreamParser.SEPARATED_STRING
      sep - the separator character

    • setParseRule

      public void setParseRule(int type, char sep, char esc)
      sets the parse rule, separator character and escape / quote character for the element to be parsed.
      e.g.
      setParseRule(ESCAPED_STRING, ',', '?') would enable parsing of [[to be?, or not to be,]]
      setParseRule(QUOTED_STRING, ',', '"') would enable parsing of [["to be, or not to be",]]

      Parameters:
      type - can be either StreamParser.ESCAPED_STRING or StreamParser.QUOTED_STRING
      sep - the separator character of this element
      esc - either the escape char of this element or the quote char

    • readElement

      public void readElement() throws Exception
      reads the next elemement from the source of this StreamParser according to the specified parse rule
      Throws:
      Exception

    • getContent

      public String getContent()
      returns the data extracted by the last readElement() call

    • rewindElement

      public void rewindElement(String string) throws IOException
      Puts the supplied String back on the source for re-reading
      Throws:
      IOException
