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. 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.

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:
