        Autodetects the encoding of the XML document supplied by the given input stream. Encoding autodetection is done according to the XML 1.0 specification, Appendix F.1: Detection Without External Encoding Information.
        Parameters:
        fname - The file name
        jar - The containing jar
        ctxt - The compilation context
        err - The error dispatcher
        Returns:
        Two-element array, where the first element (of type java.lang.String) contains the name of the (auto)detected encoding, and the second element (of type java.lang.Boolean) specifies whether the encoding was specified using the 'encoding' attribute of an XML prolog (TRUE) or autodetected (FALSE).
        Throws:
        IOException - Error reading resource
        JasperException - Other error, usually a bad encoding

        Throws:
        IOException - Thrown if i/o error occurs.

        Returns a string matching the Name production appearing immediately on the input as a symbol, or null if no Name string is present.

        Note: The Name characters are consumed.

        Note: The string returned must be a symbol. The SymbolTable can be used for this purpose.

        Returns:
        the name
        Throws:
        IOException - Thrown if i/o error occurs.

      • scanLiteral

        public int scanLiteral​(int quote,
                               XMLString content)
                        throws IOException
        Deprecated.
        Scans a range of attribute value data, setting the fields of the XMLString structure, appropriately.

        Note: The characters are consumed.

        Note: This method does not guarantee to return the longest run of attribute value data. This method may return before the quote character due to reaching the end of the input buffer or any other reason.

        Note: The fields contained in the XMLString structure are not guaranteed to remain valid upon subsequent calls to the entity scanner. Therefore, the caller is responsible for immediately using the returned character data or making a copy of the character data.

        Parameters:
        quote - The quote character that signifies the end of the attribute value data.
        content - The content structure to fill.
        Returns:
        Returns the next character on the input, if known. This value may be -1 but this does note designate end of file.
        Throws:
        IOException - Thrown if i/o error occurs.
        EOFException - Thrown on end of file.
      • scanData

        public boolean scanData​(String delimiter,
                                XMLStringBuffer buffer)
                         throws IOException
        Deprecated.
        Scans a range of character data up to the specified delimiter, setting the fields of the XMLString structure, appropriately.

        Note: The characters are consumed.

        Note: This assumes that the internal buffer is at least the same size, or bigger, than the length of the delimiter and that the delimiter contains at least one character.

        Note: This method does not guarantee to return the longest run of character data. This method may return before the delimiter due to reaching the end of the input buffer or any other reason.

        Note: The fields contained in the XMLString structure are not guaranteed to remain valid upon subsequent calls to the entity scanner. Therefore, the caller is responsible for immediately using the returned character data or making a copy of the character data.

        Parameters:
        delimiter - The string that signifies the end of the character data to be scanned.
        buffer - The data structure to fill.
        Returns:
        true if there is more data to scan, false otherwise.
        Throws:
        IOException - Thrown if i/o error occurs.
        EOFException - Thrown on end of file.

                           throws IOException
        Deprecated.
        Skips space characters appearing immediately on the input.

        Note: The characters are consumed only if they are space characters.

        Returns:
        true if at least one space character was skipped.
        Throws:
        IOException - Thrown if i/o error occurs.
