Example 26 with IModelHandler

use of org.eclipse.wst.sse.core.internal.ltk.modelhandler.IModelHandler in project webtools.sourceediting by eclipse.

the class ModelManagerImpl method reloadModel.

/**
 * This is similar to the getModel method, except this method does not use
 * the cached version, but forces the cached version to be replaced with a
 * fresh, unchanged version. Note: this method does not change any
 * reference counts. Also, if there is not already a cached version of the
 * model, then this call is essentially ignored (that is, it does not put
 * a model in the cache) and returns null.
 *
 * @deprecated - will become protected, use reload directly on model

use of org.eclipse.wst.sse.core.internal.ltk.modelhandler.IModelHandler in project webtools.sourceediting by eclipse.

the class ModelManagerImpl method createStructuredDocumentFor.

/**

 * @deprecated - TODO: to be removed by C4 do we really need this? I
 *             recommend to - use createStructuredDocumentFor(filename,
 *             null, null) - the filename does not need to represent a
 *             real - file, but can take for form of dummy.jsp, test.xml,
 *             etc. - That way we don't hard code the handler, but specify
 *             we - want the handler that "goes with" a certain type of -
 *             file.
