Interface AttributeResolver

  • All Known Implementing Classes:
    StandardAttributeResolver
    public interface AttributeResolver
    In XML, an application may or may not know how to find the ID and/or class and/or attribute defaults of an element.

    To enable matching of identity conditions, class conditions, language, and attribute defaults you need to provide an AttributeResolver to the StyleMap.

    NOTE: The application is required to look in a document's internal subset for default attribute values, but the application is not required to use its built-in knowledge of a namespace or look in the external subset.
