Parameter

Parameter	Description
line	Line which is searched for SQL commands.
delimiter	Delimiter that ends SQL command. Used for dividing specified string (line).
bufferedCommand	Already buffered command from previous searches. If there's some buffered command, this method appends the first found delimited occurence to buffered command. If there's no buffered command and the string (line) not ends with delimiter, the last part is buffered.
extractedCommands	Results list to which are found SQL commands added.

Declaration

private static void extractCommandsFromLine(final String line, final String delimiter,
        final StringBuilder bufferedCommand, final List<String> extractedCommands)
