public class REException
extends Exception
implements Serializable

This is the regular expression exception class. An exception of this type defines the three attributes:

1. A descriptive message of the error.
2. An integral type code equivalent to one of the statically defined symbols listed below.
3. The approximate position in the input string where the error occurred.

REG_BADRPT

     public static final int REG_BADRPT

  Error flag. Invalid use of repetition operators such as using `*' as the first character.

REG_BADBR

     public static final int REG_BADBR

  Error flag. Invalid use of back reference operator.

REG_EBRACE

     public static final int REG_EBRACE

  Error flag. Un-matched brace interval operators.

REG_EBRACK

     public static final int REG_EBRACK

  Error flag. Un-matched bracket list operators.

REG_ERANGE

     public static final int REG_ERANGE

  Error flag. Invalid use of the range operator, eg. the ending point of the range occurs prior to the starting point.

REG_ECTYPE

     public static final int REG_ECTYPE

  Error flag. Unknown character class name. Not implemented.

REG_EPAREN

     public static final int REG_EPAREN

  Error flag. Un-matched parenthesis group operators.

REG_ESUBREG

     public static final int REG_ESUBREG

  Error flag. Invalid back reference to a subexpression.

REG_EEND

     public static final int REG_EEND

  Error flag. Non specific error. Not implemented.

REG_ESCAPE

     public static final int REG_ESCAPE

  Error flag. Invalid escape sequence. Not implemented.

REG_BADPAT

     public static final int REG_BADPAT

  Error flag. Invalid use of pattern operators such as group or list.

REG_ESIZE

     public static final int REG_ESIZE

  Error flag. Compiled regular expression requires a pattern buffer larger than 64Kb. Not implemented.

REG_ESPACE

     public static final int REG_ESPACE

  Error flag. The regex routines ran out of memory. Not implemented.

##

getType

     public int getType()

  Returns the type of the exception, one of the constants listed above.

getPosition

     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.

getMessage

     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.

  Overrides:
    getMessage in class Throwable
