Interface InputStreamConsumer<T>

Type Parameters:
T -
public interface InputStreamConsumer<T>
Implementors consume an InputStream.

Typical usage pattern for methods that accept a consumer is to pass in an anonymous implementation of this interface: 

 
      something.withConsumer(new InputStreamConsumer<Boolean>(){
          @Override
          public Boolean withInputStream(InputStream is)  throws IOException {
              // do something with the InputStream
              return true;
          }
      });

The withConsumer method can then easily ensure that the InputStream will be closed after the consumer is done with it. 

 
   private <T> T withConsumer(final InputStreamConsumer<T> sc) {
      InputStream inputStream = new BufferedInputStream(<something something>);
      try {
          return sc.withInputStream(inputStream);
      } catch (IOException e) {
          throw new ThumbnailRenderException(e);
      } finally {
          IOUtils.closeQuietly(inputStream);
      }
  }
