John Hewson updated PDFBOX-877:
-------------------------------
Component/s: Documentation
> processOperator breaks contract - never throws IOException
> ----------------------------------------------------------
>
> Key: PDFBOX-877
> URL: https://issues.apache.org/jira/browse/PDFBOX-877
> Project: PDFBox
> Issue Type: Bug
> Components: Documentation
> Affects Versions: 1.1.0
> Reporter: Jimmy Juncker
>
> PDFStreamEngine.processOperator documents to throw IOException. However, all
> Exceptions are swallowed (in a catch Exception clause) which makes it
> impossible for us to handle:
> /**
> * This is used to handle an operation.
> *
> * @param operator The operation to perform.
> * @param arguments The list of arguments.
> *
> * @throws IOException If there is an error processing the operation.
> */
> protected void processOperator( PDFOperator operator, List arguments )
> throws IOException
> {
> try
> {
> String operation = operator.getOperation();
> OperatorProcessor processor = (OperatorProcessor)operators.get(
> operation );
> if( processor != null )
> {
> processor.setContext(this);
> processor.process( operator, arguments );
> }
> else
> {
> if (!unsupportedOperators.contains(operation))
> {
> log.info("unsupported/disabled operation: " + operation);
> unsupportedOperators.add(operation);
> }
> }
> }
> catch (Exception e)
> {
> log.warn(e, e);
> }
> }
