  - ### Method Detail

    - #### streamResource

          public boolean streamResource(Resource resource,
                               String providedChecksum,
                               Set<ResourceStreamer.Options> options)
                                 throws IOException

      Description copied from interface: `ResourceStreamer`
      Streams the content of the resource to the client (or sends an alternative response such as `HttpServletResponse.SC_NOT_MODIFIED`). Encapsulates logic for compression and for caching.
      Specified by:
        `streamResource` in interface `ResourceStreamer`
      Parameters:
        `resource` - to stream
        `providedChecksum` - checksum from URL (or null to not validate against checksum, which is normal for modules)
        `options` - enable or disable certain features
      Throws:
        `IOException`
      See Also:
        `StreamableResourceSource`

    - #### streamResource

          public boolean streamResource(StreamableResource streamable,
                               String providedChecksum,
                               Set<ResourceStreamer.Options> options)
                                 throws IOException

      Description copied from interface: `ResourceStreamer`
      Streams a resource that has been assembled elsewhere. The StreamableResource may reflect either a normal or a compressed stream, depending on the type of resource and the capabilities of the client.
      Specified by:
        `streamResource` in interface `ResourceStreamer`
      Parameters:
        `streamable` - content to stream
        `providedChecksum` - checksum provided (in the URL) to validate against the StreamableResource.getChecksum() actual checksum} for the resource, may be blank to not validate against the checksum
        `options` - enable or disable certain features
      Returns:
        true if the request was handled (even if sending a `HttpServletResponse.SC_NOT_MODIFIED` response), or false if the request was not handled (because the provided checksum did not match the actual checksum).
      Throws:
        `IOException`

    - #### streamResource

          public boolean streamResource(Resource resource,
                               StreamableResource streamable,
                               String providedChecksum,
                               Set<ResourceStreamer.Options> options)
                                 throws IOException

      Throws:
        `IOException`
