| <h6 class=CaptionFigColumn id=header>Description: </h6>The context symbol factory allows a symbol factory with a specific id to be registered to create symbols in a particular context. Clients wishing to delegate symbol construction in a particular context may then request the symbol factory based on its id. |
| |
| To get a map of registered symbol factories keyed by id, call SymbolsPlugin.getSymbolFactories(). |
| |
| The most common use of this extension point is by the JSPModelProcessor. By decorating a tag attribute with meta-data pointing to a context symbol factory with a particular id, the JSP model processor will call that symbol factory to create a symbol for that tag. |
| |
| See developer docs on decorating variable contributing tags for more information.</p> |

| <ul class=ConfigMarkup id=attlistDesc> |
| <li><b>factory</b> - An instance of AbstractContextSymbolFactory that implements the context symbol factory.</li> |
| <li><b>factoryId</b> - The id that will be used to uniquely identify this factory in meta-data or elsewhere.</li> |
| </ul> |
| <br><h6 class=CaptionFigColumn id=header>Examples: </h6><p>The following example creates a symbol factory for creating symbols.</p> |
| |
| <p> |
| <pre> |
| <p class=code id=tag><extension |
| point=<p class=code id=cstring>"org.eclipse.jst.jsf.context.symbol.contextSymbolFactory"</p><p class=code id=tag>></p> |
| <p class=code id=tag><contextSymbolFactory |

| <p class=code id=tag></extension></p> |
| </pre> |
| </p> |
| |
| <p>When the symbol factory <i>org.eclipse.jst.jsf.designtime.core.loadBundle</i> is requested, an instance of JSPDefaultSymbolFactory will be constructed.</p> |
