Example 2 with BasicStructuredDocument

use of org.eclipse.wst.sse.core.internal.text.BasicStructuredDocument in project webtools.sourceediting by eclipse.

Example 3 with BasicStructuredDocument

use of org.eclipse.wst.sse.core.internal.text.BasicStructuredDocument in project webtools.sourceediting by eclipse.

Example 4 with BasicStructuredDocument

use of org.eclipse.wst.sse.core.internal.text.BasicStructuredDocument in project webtools.sourceediting by eclipse.

the class JSPDocumentLoader method newEncodedDocument.

/**
 * This method must return a new instance of IStructuredDocument, that has
 * been initialized with appropriate parser. For many loaders, the
 * (default) parser used is known for any input. For others, the correct
 * parser (and its initialization) is normall dependent on the content of
 * the file. This no-argument method should assume "empty input" and would
 * therefore return the default parser for the default contentType. If the
 * parser is to handle tag libraries, it must have a TaglibSupport object
 * with a valid URIResolver and this IStructuredDocument attached to it
 * before the contents are set on the IStructuredDocument.

    ((BasicStructuredDocument) structuredDocument).setReParser(new JSPReParser());

    // default embeddeded content type handler
