static Object[] | getEncoding(String fname, JarFile jarFile, JspCompilationContext ctxt, ErrorDispatcher err)
Autodetects the encoding of the XML document supplied by the given
input stream.
|
boolean | isExternal() Returns true if the current entity being scanned is external. |
int | peekChar()
Returns the next character on the input.
|
int | scanChar()
Returns the next character on the input.
|
boolean | scanData(String delimiter, XMLStringBuffer buffer)
Scans a range of character data up to the specified delimiter,
setting the fields of the XMLString structure, appropriately.
|
int | scanLiteral(int quote, XMLString content)
Scans a range of attribute value data, setting the fields of the
XMLString structure, appropriately.
|
String | scanName()
Returns a string matching the Name production appearing immediately
on the input as a symbol, or null if no Name string is present.
|
String | scanPseudoAttribute(boolean scanningTextDecl, XMLString value)
Scans a pseudo attribute.
|
boolean | skipChar(int c)
Skips a character appearing immediately on the input.
|
boolean | skipSpaces()
Skips space characters appearing immediately on the input.
|
boolean | skipString(String s)
Skips the specified string appearing immediately on the input.

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).
Note: The character is not consumed.
Throws: IOException Thrown if i/o error occurs. EOFException Thrown on end of file.
Note: The character is consumed.
Throws: IOException Thrown if i/o error occurs. EOFException Thrown on end of file.
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: 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.
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.
Note: The Name characters are consumed.
Note: The string returned must be a symbol. The SymbolTable can be used for this purpose.
Throws: IOException Thrown if i/o error occurs. EOFException Thrown on end of file.

Parameters: scanningTextDecl True if scanning this pseudo-attribute for a TextDecl; false if scanning XMLDecl. This flag is needed to report the correct type of error. value The string to fill in with the attribute value.
Returns: The name of the attribute Note: This method uses fStringBuffer2, anything in it at the time of calling is lost.
Note: The character is consumed only if it matches the specified character.
Parameters: c The character to skip.
Returns: Returns true if the character was skipped.
Throws: IOException Thrown if i/o error occurs. EOFException Thrown on end of file.
Note: The characters are consumed only if they are space characters.
Returns: Returns true if at least one space character was skipped.
Throws: IOException Thrown if i/o error occurs. EOFException Thrown on end of file.
See Also: XMLChar
Note: The characters are consumed only if they are space characters.
Parameters: s The string to skip.
Returns: Returns true if the string was skipped.
Throws: IOException Thrown if i/o error occurs. EOFException Thrown on end of file.
