Method Detail

getState

protected AbstractEmbeddedState getState()

Description copied from class: AbstractComponent

Returns the shared state bean with information to be sent from the server to the client. Subclasses should override this method and set any relevant fields of the state returned by super.getState().

Overrides:

getState in class AbstractComponent

Returns:

updated component shared state

getState

protected AbstractEmbeddedState getState(boolean markAsDirty)

Description copied from class: AbstractClientConnector

Returns the shared state for this connector.

Overrides:

getState in class AbstractComponent

Parameters:

markAsDirty - true if the connector should automatically be marked dirty, false otherwise

Returns:

The shared state for this connector. Never null.

See Also:

AbstractClientConnector.getState()

setSource

public void setSource(Resource source)

Sets the object source resource. The dimensions are assumed if possible. The type is guessed from resource.

Parameters:

source - the source to set.

getSource

public Resource getSource()

Get the object source resource.

Returns:

the source

setAlternateText

public void setAlternateText(String altText)

Sets this component's alternate text that can be presented instead of the component's normal content for accessibility purposes.

Parameters:

altText - A short, human-readable description of this component's content.

getAlternateText

public String getAlternateText()

Gets this component's alternate text that can be presented instead of the component's normal content for accessibility purposes.

readDesign

public void readDesign(org.jsoup.nodes.Element design,
                       DesignContext designContext)

Description copied from interface: Component

Reads the component state from the given design.

The component is responsible not only for updating its own state but also for ensuring that its children update their state based on the design.

It is assumed that the component is in its default state when this method is called. Reading should only take into consideration attributes specified in the design and not reset any unspecified attributes to their defaults.

This method must not modify the design.

Specified by:

readDesign in interface Component

Overrides:

readDesign in class AbstractComponent

Parameters:

design - The element to obtain the state from

designContext - The DesignContext instance used for parsing the design

writeDesign

public void writeDesign(org.jsoup.nodes.Element design,
                        DesignContext designContext)

Description copied from interface: Component

Writes the component state to the given design.

The component is responsible not only for writing its own state but also for ensuring that its children write their state to the design.

This method must not modify the component state.

Specified by:

writeDesign in interface Component

Overrides:

writeDesign in class AbstractComponent

Parameters:

design - The element to write the component state to. Any previous attributes or child nodes are not cleared.

designContext - The DesignContext instance used for writing the design

getCustomAttributes

protected Collection<String> getCustomAttributes()

Description copied from class: AbstractComponent

Returns a collection of attributes that should not be handled by the basic implementation of the readDesign and writeDesign methods. Typically these are handled in a custom way in the overridden versions of the above methods

Overrides:

getCustomAttributes in class AbstractComponent

Returns:

the collection of attributes that are not handled by the basic implementation
