  • Method Details

    • 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:
      the max number of cached files.

    • setMaxCachedFiles

      public void setMaxCachedFiles(int maxCachedFiles)
      Parameters:
      maxCachedFiles - the max number of cached files.

    • isUseFileMappedBuffer

      public boolean isUseFileMappedBuffer()

    • flushCache

      public void flushCache()

    • getContent

      public HttpContent getContent(String pathInContext, int maxBufferSize) throws IOException

      Returns an entry from the cache, or creates a new one.

      Specified by:
      getContent in interface HttpContent.ContentFactory
      Parameters:
      pathInContext - The key into the cache
      maxBufferSize - The maximum buffer size allocated for this request. For cached content, a larger buffer may have previously been allocated and returned by the HttpContent.getDirectBuffer() or HttpContent.getIndirectBuffer() calls.
      Returns:
      The entry matching pathInContext, or a new entry if no matching entry was found. If the content exists but is not cacheable, then a ResourceHttpContent instance is returned. If the resource does not exist, then null is returned.
      Throws:
      IOException - if the resource cannot be retrieved

    • isCacheable

      protected boolean isCacheable(Resource resource)
      Parameters:
      resource - the resource to test
      Returns:
      whether the resource is cacheable. The default implementation tests the cache sizes.

    • getIndirectBuffer

      protected ByteBuffer getIndirectBuffer(Resource resource)

    • getMappedBuffer

      protected ByteBuffer getMappedBuffer(Resource resource)

    • getDirectBuffer

      protected ByteBuffer getDirectBuffer(Resource resource)

    • toString

      public String toString()
      Overrides:
      toString in class Object
