Method Detail

streamResource

public boolean streamResource(Resource resource,
                              java.lang.String providedChecksum,
                              java.util.Set<ResourceStreamer.Options> options)
                       throws java.io.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:

java.io.IOException

streamResource

public boolean streamResource(StreamableResource streamable,
                              java.lang.String providedChecksum,
                              java.util.Set<ResourceStreamer.Options> options)
                       throws java.io.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:

java.io.IOException
