Field Detail

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.
Method Detail

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 java.lang.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 java.lang.Throwable
