    HSSFListener

    public abstract class AbortableHSSFListener
    extends Object
    implements HSSFListener
    Interface for use with the HSSFRequest and HSSFEventFactory. Users should create a listener supporting this interface and register it with the HSSFRequest (associating it with Record SID's).

      • abortableProcessRecord

        public abstract short abortableProcessRecord​(Record record)
                                              throws HSSFUserException
        Process an HSSF Record. Called when a record occurs in an HSSF file. Provides two options for halting the processing of the HSSF file. The return value provides a means of non-error termination with a user-defined result code. A value of zero must be returned to continue processing, any other value will halt processing by HSSFEventFactory with the code being passed back by its abortable process events methods. Error termination can be done by throwing the HSSFUserException. Note that HSSFEventFactory will not call the inherited process
        Returns:
        result code of zero for continued processing.
        Throws:
        HSSFUserException - User code can throw this to abort file processing by HSSFEventFactory and return diagnostic information.
