Example 1 with StructuredTextPartitionerForJSP

use of org.eclipse.jst.jsp.core.internal.text.StructuredTextPartitionerForJSP in project webtools.sourceediting by eclipse.

the class JSPModelLoader method reInitializeEmbeddedType.

 * default one assigned, before we start checking the stream

    // once we know the embedded content type, we need to set it in the
    // PageDirectiveAdapter ... the order of initialization is
    // critical here, the doc must have been created, but its contents not
    // set yet,
    // and all factories must have been set up also.

    // reinit path, we need to remove all adapters,
    // except for the propagated adapters (including page
    // directive adapter, and model query adapter).
    // to accomplish this, we'll just remove all, then
    // add back with a call to pre-load adapt.

    }
    // adding language here, in this convienent central
    // location, but some obvious renaming or refactoring
    // wouldn't hurt, in future.

    // the model has an ID, so we can look up IFile, etc.
