Examples with IResourceStream org.apache.wicket.util.resource.IResourceStream used on opensource projects

Example 1 with IResourceStream

use of org.apache.wicket.util.resource.IResourceStream in project midpoint by Evolveum.

the class AjaxDownloadBehaviorFromStream method onRequest.

public void onRequest() {
    final InputStream byteStream = initStream();
    if (byteStream == null) {
        return;
    }
    IResourceStream resourceStream = new AbstractResourceStream() {

        @Override
        public String getContentType() {
            return contentType;
        }

        @Override
        public InputStream getInputStream() throws ResourceStreamNotFoundException {
            return byteStream;
        }

        @Override
        public void close() throws IOException {
            byteStream.close();
        }
    };
    ResourceStreamRequestHandler reqHandler = new ResourceStreamRequestHandler(resourceStream) {

        @Override
        public void respond(IRequestCycle requestCycle) {
            super.respond(requestCycle);
        }
    }.setContentDisposition(ContentDisposition.ATTACHMENT).setCacheDuration(Duration.ONE_SECOND);
    if (StringUtils.isNotEmpty(getFileName())) {
        reqHandler.setFileName(getFileName());
    }
    getComponent().getRequestCycle().scheduleRequestHandlerAfterCurrent(reqHandler);
}

Example 2 with IResourceStream

the class AjaxDownloadBehaviorFromFile method onRequest.

public void onRequest() {
    final File file = initFile();
    IResourceStream resourceStream = new FileResourceStream(new File(file));
    getComponent().getRequestCycle().scheduleRequestHandlerAfterCurrent(new ResourceStreamRequestHandler(resourceStream) {

        @Override
        public void respond(IRequestCycle requestCycle) {
            try {
                super.respond(requestCycle);
            } finally {
                if (removeFile) {
                    LOGGER.debug("Removing file '{}'.", new Object[] { file.getAbsolutePath() });
                    Files.remove(file);
                }
            }
        }
