Example 1 with HttpContent

Example 2 with HttpContent

use of org.eclipse.jetty.http.HttpContent in project jetty.project by eclipse.

the class ResourceContentFactory method getContent.

/* ------------------------------------------------------------ */
@Override

    // try loading the content from our factory.
    Resource resource = _factory.getResource(pathInContext);
    HttpContent loaded = load(pathInContext, resource, maxBufferSize);

Example 3 with HttpContent

use of org.eclipse.jetty.http.HttpContent in project jetty.project by eclipse.

the class CachedContentFactory method getContent.

/* ------------------------------------------------------------ */
/** Get a Entry from the cache.
     * Get either a valid entry object or create a new one if possible.
     *
     * @param pathInContext The key into the cache
     * @param maxBufferSize The maximum buffer to allocated for this request.  For cached content, a larger buffer may have
     * previously been allocated and returned by the {@link HttpContent#getDirectBuffer()} or {@link HttpContent#getIndirectBuffer()} calls.
     * @return The entry matching <code>pathInContext</code>, or a new entry 
     * if no matching entry was found. If the content exists but is not cachable, 
     * then a {@link ResourceHttpContent} instance is return. If 
     * the resource does not exist, then null is returned.
     * @throws IOException Problem loading the resource
