createDocument

public static CmsXmlGroupContainer createDocument(CmsObject cms,
                                                  java.util.Locale locale,

locale - the locale to generate the default content for

modelUri - the absolute path to the group container file acting as model

Returns:

the created group container

Throws:

CmsException - in case the model file is not found or not valid

createDocument

public static CmsXmlGroupContainer createDocument(CmsObject cms,
                                                  java.util.Locale locale,

unmarshal

public static CmsXmlGroupContainer unmarshal(CmsObject cms,
                                             byte[] xmlData,
                                             java.lang.String encoding,

                                      throws CmsXmlException

Factory method to unmarshal (generate) a group container instance from a byte array that contains XML data.

When unmarshalling, the encoding is read directly from the XML header of the byte array. The given encoding is used only when marshalling the XML again later.

Warning:
This method does not support requested historic versions, it always loads the most recent version. Use unmarshal(CmsObject, CmsResource, ServletRequest) for history support.

Parameters:

cms - the cms context

xmlData - the XML data in a byte array

encoding - the encoding to use when marshalling the XML content later

resolver - the XML entitiy resolver to use

Returns:

a group container instance unmarshalled from the byte array

Throws:

CmsXmlException - if something goes wrong

unmarshal

public static CmsXmlGroupContainer unmarshal(CmsObject cms,
                                             CmsFile file)
                                      throws CmsXmlException

Factory method to unmarshal (read) a group container instance from a OpenCms VFS file that contains XML data.

Warning:
This method does not support requested historic versions, it always loads the most recent version. Use unmarshal(CmsObject, CmsResource, ServletRequest) for history support.

Parameters:

cms - the current cms object

file - the file with the XML data to unmarshal

Returns:

a group container instance unmarshalled from the provided file

Throws:

CmsXmlException - if something goes wrong

unmarshal

                                      throws CmsXmlException

Factory method to unmarshal (read) a group container instance from a OpenCms VFS file that contains XML data, using wither the encoding set in the XML file header, or the encoding set in the VFS file property.

If you are not sure about the implications of the encoding issues, use unmarshal(CmsObject, CmsFile) instead.

Warning:
This method does not support requested historic versions, it always loads the most recent version. Use unmarshal(CmsObject, CmsResource, ServletRequest) for history support.

Parameters:
