Interface IContentDescriber

  • All Known Subinterfaces:
    ITextContentDescriber
    All Known Implementing Classes:
    BinarySignatureDescriber, org.eclipse.core.internal.content.TextContentDescriber, XMLContentDescriber, XMLRootElementContentDescriber, XMLRootElementContentDescriber2

    public interface IContentDescriber
    Content describers know how to retrieve metadata from contents.

    Note: It is expected that content describer implementations be declared in a package that is exempt from plug-in activation (using the Eclipse-AutoStart bundle manifest header). Since all describers are instantiated when the content type framework is initialized, failure in complying with this requirement causes premature activation, which must be avoided. Future implementations of the framework might refuse to instantiate describers if doing so would trigger activation of the corresponding plug-in.

    Describers for text-based content types should implement ITextContentDescriber instead.

    Clients may implement this interface.
