Class Content

java.lang.Object
  extended by yarfraw.core.datamodel.Content
All Implemented Interfaces:
Serializable
public class Content
extends Object

  • Rss 2.0 - This is not officially supported, but if there's a <content:encoded /> element under <Item>, the content of the encoded element will be mapped to this class. The type will always be 'text' in this case.
  • Rss 1.0 - This is not officially supported, but if there's a <content:encoded /> element under <Item>, the content of the encoded element will be mapped to this class. The type will always be 'text' in this case.
  • Atom 1.0 - Data model of the 'atom:content' element in Atom 1.0 specs.
    http://atompub.org/2005/07/11/draft-ietf-atompub-format-10.html#atomContent
    If the content is XHTML, the xhtml elements can be found at the 'otherElements' list.

    Content

    public Content(String contentText)
    Method Detail

    addContentText

    public Content addContentText(String contentText)
    Any text content.

    getContentText

    public List<String> getContentText()
    Any text content.

    setContentText

    public Content setContentText(List<String> contentText)
    Any text content.

    getSrc

    public String getSrc()
    Atom 1.0 only
    atom:content MAY have a "src" attribute, whose value MUST be an IRI reference [RFC3987]. If the "src" attribute is present, atom:content MUST be empty. Atom Processors MAY use the IRI to retrieve the content, and MAY chose to ignore remote content or present it in a different manner than local content.

    If the "src" attribute is present, the "type" attribute SHOULD be provided and MUST be a MIME media type [MIMEREG], rather than "text", "html", or "xhtml". The value is advisory; that is to say, when the corresponding URI (mapped from an IRI, if necessary), is dereferenced, if the server providing that content also provides a media type, the server-provided media type is authoritative.

    setSrc

    public Content setSrc(String src)
    Atom 1.0 only
    atom:content MAY have a "src" attribute, whose value MUST be an IRI reference [RFC3987]. If the "src" attribute is present, atom:content MUST be empty. Atom Processors MAY use the IRI to retrieve the content, and MAY chose to ignore remote content or present it in a different manner than local content.

    If the "src" attribute is present, the "type" attribute SHOULD be provided and MUST be a MIME media type [MIMEREG], rather than "text", "html", or "xhtml". The value is advisory; that is to say, when the corresponding URI (mapped from an IRI, if necessary), is dereferenced, if the server providing that content also provides a media type, the server-provided media type is authoritative.

    getType

    public String getType()
    Atom 1.0 only
    On the atom:content element, the value of the "type" attribute MAY be one of "text", "html", or "xhtml". Failing that, it MUST conform to the syntax of a MIME media type, but MUST NOT be a composite type (see Section 4.2.6 of [MIMEREG]). If the type attribute is not provided, Atom Processors MUST behave as though it were present with a value of "text".

    setType

    public Content setType(String type)
    Atom 1.0 only
    On the atom:content element, the value of the "type" attribute MAY be one of "text", "html", or "xhtml". Failing that, it MUST conform to the syntax of a MIME media type, but MUST NOT be a composite type (see Section 4.2.6 of [MIMEREG]). If the type attribute is not provided, Atom Processors MUST behave as though it were present with a value of "text".

    setOtherElements

    public Content addOtherElement(String xmlString)
                        throws SAXException,
                               IOException,
                               ParserConfigurationException

    setBase

    public Content setBase(String base)
    Atom 1.0 only
    Any element defined by this specification MAY have an xml:base attribute [W3C.REC-xmlbase-20010627].
