Class ZipContentItem

Method Details

• getMimeType

  public String getMimeType() throws ContentIOException

  Description copied from interface: ContentItem

  Returns the mime type for the content entity. If the repository does not store mimetypes, this call usually uses the repositories MimeRegistry to resolve the mimetype.

  Specified by:

  getMimeType in interface ContentItem

  Returns:

  the mime type.

  Throws:

  ContentIOException - if an error occured.

• getOutputStream

  public OutputStream getOutputStream() throws ContentIOException, IOException

  Description copied from interface: ContentItem

  Tries to open and return a output stream for writing into the content item. This call will fail if the item is not writeable. Whether opening multiple output streams at the same time is possible is implementation dependent, but it is generally not recommended to try this.

  Having both an input and output stream open at the same time is not guaranteed to work. Generally if you need to append data, first open the inputstream and copy the content to a temporary location and then write the content along with the appended content to the new output stream.

  Specified by:

  getOutputStream in interface ContentItem

  Returns:

  the output stream for writing the item.

  Throws:

  ContentIOException - if an repository related error prevents the creation of the output stream.

  IOException - if an IO error occurs.

• getInputStream

  public InputStream getInputStream() throws ContentIOException, IOException

  Description copied from interface: ContentItem

  Tries to open and return a input stream for reading from the content item. This call will fail if the item is not readable. Whether opening multiple input streams at the same time is possible is implementation dependent.

  Having both an input and output stream open at the same time is not guaranteed to work. Generally if you need to append data, first open the inputstream and copy the content to a temporary location and then write the content along with the appended content to the new output stream.

  Specified by:

  getInputStream in interface ContentItem

  Returns:

  the input stream for reading from the item.

  Throws:

  ContentIOException - if an repository related error prevents the creation of the input stream.

  IOException - if an IO error occurs.

• isReadable

  public boolean isReadable()

  Description copied from interface: ContentItem

  Checks, whether the content item is readable. A content item that is not readable will never return a valid inputstream and any call to getInputStream is bound to fail.

  Specified by:

  isReadable in interface ContentItem

  Returns:

  true, if the content item is readable, false otherwise.

• isWriteable

  public boolean isWriteable()

  Description copied from interface: ContentItem

  Checks, whether the content item is writable. A content item that is not writable will never return a valid outputstream and any call to getOutputStream is bound to fail.

  Specified by:

  isWriteable in interface ContentItem

  Returns:

  true, if the content item is writeable, false otherwise.

• getName

  public String getName()

  Description copied from interface: ContentEntity

  Returns the name of the entry.

  the name, never null.

• getContentId

  public Object getContentId()

  Description copied from interface: ContentEntity

  Returns a unique identifier. This can be canonical filename or a database key. It must be guaranteed that within the same repository the key will be unique.

  Specified by:

  getContentId in interface ContentEntity

  Returns:

  the unique content ID.

• getAttribute

  public Object getAttribute(String domain, String key)

  Description copied from interface: ContentEntity

  Returns:

  the value or null, if the content-entity does not have a value for this attribute.

• setAttribute

  public boolean setAttribute(String domain, String key, Object value)

  Description copied from interface: ContentEntity

  Updates the attribute value for the given attribute domain and name. If the element is not writable or the attribute could not be updated for any other reason, the method will return false. This method only returns true, if the attribute has been updated successfully.

  Specified by:

  setAttribute in interface ContentEntity

  Parameters:

  domain - the attribute domain.

  key - the attribute name

  value - the new attribute value.
