- - ### Constructor Detail

    - #### AbstractArchiveResource

          protected AbstractArchiveResource(AbstractArchiveResourceSet archiveResourceSet,
                                 String webAppPath,
                                 String baseUrl,
                                 JarEntry jarEntry,
                                 String codeBaseUrl)

  - ### Method Detail

    - #### getArchiveResourceSet

          protected AbstractArchiveResourceSet getArchiveResourceSet()

    - #### getBase

          protected final String getBase()

    - #### getBaseUrl

          protected final String getBaseUrl()

    - #### getResource

          protected final JarEntry getResource()

    - #### getLastModified

          public long getLastModified()

      Returns:

    - #### isVirtual

          public boolean isVirtual()

      Description copied from interface: `WebResource`

          public long getContentLength()

      Returns:
        `File.length()`.

    - #### getCanonicalPath

          public String getCanonicalPath()

        a URL to access the resource or `null` if no such URL is available or if the resource does not exist.

    - #### getCodeBase

          public URL getCodeBase()

      Returns:
        the code base for this resource that will be used when looking up the assigned permissions for the code base in the security policy file when running under a security manager.

    - #### getContent

          public final byte[] getContent()

      Returns:
        the binary content of this resource or `null` if it is not available in a byte[] because, for example, it is too big.
