Class GuiMappingContext

java.lang.Object
org.autogui.base.mapping.GuiMappingContext
public class GuiMappingContext extends Object
a tree node describing a mapping between GuiTypeElement and GuiRepresentation. The tree constructs an abstract GUI representation of an object tree (like HTML DOM tree).

First, an instance of this class is created with a GuiTypeElement tree of a target object: GuiMappingContext(GuiTypeElement). The type-element tree can be obtained by GuiTypeBuilder.

Second, GuiReprSet receives the unmapped context object, and constructs subtrees. The subtrees are created by using createChildCandidates() and matched with GuiReprSet.match(GuiMappingContext). The only matched sub-context becomes an actual child of a context by addToParent(). Also, if matched, the context becomes to have a GuiRepresentation. The entry point of construction can be the match method of GuiRepresentation.getDefaultSet().

Third, concrete entities of GuiRepresentations, like GuiSwingView, can create concrete GUI components. Then the components can compute updating of their displays by using retained mapped objects and listeners, which can be obtained by getSource() and getListeners().

  1. a GUI component can call updateSourceFromRoot(GuiMappingContext) with passing an associated context. Note, updateSourceFromRoot()) is the no-source version and can be used for obtaining initial values.
  2. The method obtains the root context by getRoot(),
  3. and traverses the tree and collects updated contexts, by collectUpdatedSource(GuiMappingContext, List).
  4. GuiRepresentation.checkAndUpdateSource(GuiMappingContext) do the actual computation of checking the update.
  5. After that, GuiMappingContext.SourceUpdateListener.update(GuiMappingContext, Object, GuiTaskClock) of each updated context will be called.

getType...(), isType...() check and obtain typeElement as a specified type. isParent...() check the type of the parent.
