Examples of AbstractImagePrototype

com.google.gwt.user.client.ui.AbstractImagePrototype
An opaque representation of a particular image such that the image can be accessed either as an HTML fragment or as an {@link Image} object. An imageprotype can be thought of as an abstract image factory with additional capabilities.
The {@link #applyTo(Image)} method provides an efficient way to replace thecontents of an existing Image. This is useful in cases where an image changes its appearance based on a user's action. Instead of creating two Image objects then alternately hiding/showing them, one can use the {@link #applyTo(Image)} method of twoAbstractImagePrototype objects to transform a single Image object between two (or more) visual representations. The use of AbstractImagePrototypes results in an cleaner and more efficient implementation.

This class is also a useful way to encapsulate complex HTML that represents an image without actually instantiating Image objects. When constructing large HTML fragments, especially those that contain many images, {@link #getHTML()} can be much more efficient.

        String actualMessage = message.getConciseMessage().length()>30 ? message.getConciseMessage().substring(0, 30)+" ..." : message.getConciseMessage();
