This extension point is used to customize the initialization process of a document for a text file buffer manager by this plug-in's default text file buffer manager. It allows to specify which document setup participant should be involved in the initialization process for a text file buffer created for a certain file content type, file extension, or file name. <p> <strong>Note:</strong> Participants have to be aware of the existence of other participants i.e. they should always setup a document in a way that does not interfere with others. E.g., when a participant wants to install partitioning on the document, it must use the <code>org.eclipse.jface.text.IDocumentExtension3</code> API and choose a unique partitioning id. As of 3.2, a warning is written to the log file if this isn't followed. </p> The specification of a document setup participant. In order find all participants for a given file the attributes of each participant specification are consulted in the following sequence: contentTypeId, fileNames, extensions. If multiple participants are found, the sequence in which they are called is not specified. The fully qualified name of the participant implementation class. This class must implement the org.eclipse.core.filebuffers.IDocumentSetupParticipant interface. A comma separated list of file extensions for which this participant should be used. A comma separated list of file names for which this participant should be used. The id of a content type as defined by the org.eclipse.core.runtime.contentTypes extension point for which this participant should be used. 3.0 <pre> <extension id="JavaDocumentSetupParticipant" name="%javaDocumentSetupParticipant" point="org.eclipse.core.filebuffers.documentSetup"> <participant extensions="java" class="org.eclipse.jdt.internal.ui.javaeditor.JavaDocumentSetupParticipant"> </participant> </extension> </pre> Document setup participants have to implement org.eclipse.core.filebuffers.IDocumentSetupParticipant.
