org.exolab.castor.xml.dtd.parser.InputCharStream

An implementation of interface {@link org.exolab.castor.xml.dtd.parser.CharStream CharStream}. Implements input character stream that maintains line and column number positions of the characters. It also has the capability to backup the stream to some extent.
The object of this class is constructed using {@link java.io.Reader java.io.Reader} reader and it is left toconstructor of the reader to set up character encoding correctly. This means that method read of the reader is used to get next characters, assuming it returns appropriate values. It is recommended to use class {@link java.io.InputStreamReader java.io.InputStreamReader}as a reader, which allows to set desired character encoding. This class is an intermediate component between input character reader and the parser.
The code of this class is based on the class ASCII_CharStream - implementation of interface {@link org.exolab.castor.xml.dtd.parser.CharStream CharStream}, that JavaCC would have generated with the following options set in a JavaCC grammar file:

 JAVA_UNICODE_ESCAPE = false; UNICODE_INPUT = false; USER_CHAR_STREAM = false;

Note that this class is not fully JavaCC generated.
