Field Detail

lengthHandler

protected LengthHandler lengthHandler
The length handler used to report parse events.

eRead

protected boolean eRead
Whether the last character was a 'e' or 'E'.
Constructor Detail

LengthParser

public LengthParser()
Creates a new LengthParser.
Method Detail

setLengthHandler

public void setLengthHandler(LengthHandler handler)
Allows an application to register a length handler.

If the application does not register a handler, all events reported by the parser will be silently ignored.

Applications may register a new or different handler in the middle of a parse, and the parser must begin using the new handler immediately.

Parameters:
handler - The transform list handler.

getLengthHandler

public LengthHandler getLengthHandler()
Returns the length handler in use.

parse

public void parse(java.io.Reader r)
           throws ParseException
Parses the given reader.

parseLength

protected void parseLength()
                    throws ParseException,
                           java.lang.NumberFormatException
Parses a length value.

readNumber

protected void readNumber()
                   throws ParseException
Implements NumberParser.readNumber().
Overrides:
readNumber in class NumberParser
