    • parse

      public void parse(java.lang.String string)
      Parses the given input string. The input must contain a valid JSON value, optionally padded with whitespace.
      Parameters:
      string - the input string, must be valid JSON
      Throws:
      ParseException - if the input is not valid JSON
    • parse

      public void parse(java.io.Reader reader) throws java.io.IOException
      Reads the entire input from the given reader and parses it as JSON. The input must contain a valid JSON value, optionally padded with whitespace.

      Characters are read in chunks into a default-sized input buffer. Hence, wrapping a reader in an additional BufferedReader likely won't improve reading performance.

      Parameters:
      reader - the reader to read the input from
      Throws:
      java.io.IOException - if an I/O error occurs in the reader
      ParseException - if the input is not valid JSON

      public void parse(java.io.Reader reader, int buffersize) throws java.io.IOException
      Reads the entire input from the given reader and parses it as JSON. The input must contain a valid JSON value, optionally padded with whitespace.

      Characters are read in chunks into an input buffer of the given size. Hence, wrapping a reader in an additional BufferedReader likely won't improve reading performance.

      Parameters:
      reader - the reader to read the input from
      buffersize - the size of the input buffer in chars
      Throws:
      java.io.IOException - if an I/O error occurs in the reader
