Interface ContentVariation

All Superinterfaces:

Versionable

@ProviderType
public interface ContentVariation
extends Versionable

Implementations of this interface allow to access a variation of a content element through a stable API, agnostic to the underlying content structure.

Variations can be synchronized with some other element. If the implementation does not provide enhances synchronization capabilities (which it is free to do), it should synchronize with the element content.

The synchronization works by using the synchronization source, taking their content, optionally applying some rules and then updating the variation with that content.

How the synchronization source is defined and how the source content is processed is implementation specific. This API only provides means to manage the synchronization state and triggering the synchronization.

The synchronization state is represented by the SyncStatus enumeration.

Transactional behavior: The caller is responsible for committing the respective ResourceResolver after calling one or more methods that change a content fragment unless specified otherwise.

Method Summary

Modifier and Type	Method and Description
java.lang.String	getContent() Gets the content of the variation in a suitable text representation.
java.lang.String	getContentType() Gets the MIME type of the variation.
java.lang.String	getDescription() Gets a description for the variation.
java.lang.String	getName() Gets the (technical) name of the variation.
SyncStatus	getSyncStatus() Gets the synchronization status of the variation.
java.lang.String	getTitle() Gets the (human-readable) title of the variation.
FragmentData	getValue() Gets the current value of the variation in a suitable object representation.
void	setContent(java.lang.String content, java.lang.String contentType) Sets the content of the variation from the provided text value.
void	setDescription(java.lang.String description) Sets the current description of the variation in the provided object representation.
void	setTitle(java.lang.String title) Sets the current title of the variation in the provided object representation.
void	setValue(FragmentData object) Sets the current value of the variation in the provided object representation.
void	synchronize() Synchronizes the variation.

Method Detail

getName

java.lang.String getName()

Gets the (technical) name of the variation.

Returns:

The name of the variation

getTitle

java.lang.String getTitle()

Gets the (human-readable) title of the variation.

Returns:

The title of the variation

setTitle

void setTitle(java.lang.String title)
       throws ContentFragmentException

Sets the current title of the variation in the provided object representation.

Parameters:

title - The new title of the variation

Throws:

ContentFragmentException - if the provided value couldn't be persisted

getDescription

java.lang.String getDescription()

Gets a description for the variation.

Returns:

The description

setDescription

void setDescription(java.lang.String description)
             throws ContentFragmentException

Sets the current description of the variation in the provided object representation.

Parameters:

description - The new description of the variation

Throws:

ContentFragmentException - if the provided value couldn't be persisted

getValue

FragmentData getValue()

Gets the current value of the variation in a suitable object representation.

Note that if you change the returned FragmentData, you will have to call setValue(FragmentData) explicitly after manipulating the value.

DataType provides additional information about how values are handled by the system.

Returns:

The value

Since:

1.1

setValue

void setValue(FragmentData object)
       throws ContentFragmentException

Sets the current value of the variation in the provided object representation.

Please see DataType for more information about what "object representation" means.

Parameters:

object - The value

Throws:

ContentFragmentException - if the provided value couldn't be persisted or doesn't match the data type of the variation

Since:

1.1

getContentType

java.lang.String getContentType()

Gets the MIME type of the variation.

Returns:

The MIME type; refers to some text format

getContent

java.lang.String getContent()

Gets the content of the variation in a suitable text representation.

Returns:

The content of the variation (in a text representation)

setContent

void setContent(java.lang.String content,
                java.lang.String contentType)
         throws ContentFragmentException

Sets the content of the variation from the provided text value.

The specified content & its MIME type must be textual. What MIME types are eventually supported is left to the implementation.

For non-textual data types (added in 1.1), a MIME type of text/plain should be specified. The implementation is then responsible for translating the provided text value into a suitable object representation (or throw a ContentFragmentException if this is not possible). How the text value is converted into a suitable object value is left to the implementation. But it is required that a value returned by getContent() can successfully be converted by setContent(String, String). In other words, el.setContent(el.getContent(), el.getContentType() must not throw a ContentFragmentException because of type conversion problems.

Parameters:

content - The content

contentType - The MIME type of the content

Throws:

ContentFragmentException - if the content could not be written or the provided text could not be converted to the data type of the underlying element correctly

java.lang.IllegalArgumentException - if the specified MIME type is not supported or not a textual MIME type

getSyncStatus

SyncStatus getSyncStatus()

Gets the synchronization status of the variation.

Returns:

The synchronization state of the provided variation

synchronize

void synchronize()
          throws ContentFragmentException

Synchronizes the variation.

Throws:

ContentFragmentException - if the synchronization failed
