    - #### ResourceCache

          public ResourceCache(ResourceCache parent,
                       ResourceFactory factory,
                       MimeTypes mimeTypes)

      Constructor.
      Parameters:
        `mimeTypes` - Mimetype to use for meta data

  - ### Method Detail

    - #### getCachedSize

          public int getCachedSize()

    - #### getCachedFiles

          public int getCachedFiles()

    - #### getMaxCachedFileSize

          public int getMaxCachedFileSize()

    - #### setMaxCachedFileSize

          public void setMaxCachedFileSize(int maxCachedFileSize)

    - #### getMaxCacheSize

          public int getMaxCacheSize()

    - #### setMaxCacheSize

          public void setMaxCacheSize(int maxCacheSize)

    - #### getMaxCachedFiles

          public int getMaxCachedFiles()

      Returns:
        Returns the maxCachedFiles.

    - #### setMaxCachedFiles

          public void setMaxCachedFiles(int maxCachedFiles)

      Parameters:
        `maxCachedFiles` - The maxCachedFiles to set.

    - #### isUseFileMappedBuffer

          public boolean isUseFileMappedBuffer()

    - #### setUseFileMappedBuffer

          public void setUseFileMappedBuffer(boolean useFileMappedBuffer)

    - #### flushCache

          public void flushCache()

    - #### lookup

          public HttpContent lookup(String pathInContext)
                             throws IOException

      Get a Entry from the cache. Get either a valid entry object or create a new one if possible.
      Parameters:
        `pathInContext` - The key into the cache
      Returns:
        The entry matching `pathInContext`, or a new entry if no matching entry was found. If the content exists but is not cachable, then a `HttpContent.ResourceAsHttpContent` instance is return. If the resource does not exist, then null is returned.
      Throws:
        `IOException` - Problem loading the resource

    - #### isCacheable

          protected boolean isCacheable(Resource resource)

      Parameters:
        `resource` -
      Returns:
        True if the resource is cacheable. The default implementation tests the cache sizes.

    - #### getIndirectBuffer

          protected Buffer getIndirectBuffer(Resource resource)

    - #### getDirectBuffer

          protected Buffer getDirectBuffer(Resource resource)

    - #### toString

          public String toString()
