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 AbstractTextField

Parameters:

design - The design as HTML 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 AbstractTextField

Parameters:

design - The design as HTML to update with the current state
