REException
extends Exception
This is the regular expression exception class. An exception of this type
defines the three attributes:
- A descriptive message of the error.
- An integral type code equivalent to one of the statically
defined symbols listed below.
- The approximate position in the input string where the error
occurred.

REException(String msg, int type, int position)
public String getMessage()
Reports the descriptive message associated with this exception
as well as its index position in the string or character array
being compiled.
public int getPosition()
Returns the position, relative to the string or character array being
compiled, where the error occurred. This position is generally the point
where the error was detected, not necessarily the starting index of
a bad subexpression.
public int getType()
Returns the type of the exception, one of the constants listed above.
