    • isSpecializationOf

      public boolean isSpecializationOf(MediaType a, MediaType b)
      Deprecated.
      Checks whether the given media type a is a specialization of a more generic type b. Both types should be already normalised.
      Parameters:
      a - media type, normalised
      b - suspected supertype, normalised
      Returns:
      true if b is a supertype of a, false otherwise

    • isInstanceOf

      public boolean isInstanceOf(MediaType a, MediaType b)
      Deprecated.
      Checks whether the given media type equals the given base type or is a specialization of it. Both types should be already normalised.
      Parameters:
      a - media type, normalised
      b - base type, normalised
      Returns:
      true if b equals a or is a specialization of it, false otherwise
      Since:
      Apache Tika 1.2

    • isInstanceOf

      public boolean isInstanceOf(String a, MediaType b)
      Deprecated.
      Parses and normalises the given media type string and checks whether the result equals the given base type or is a specialization of it. The given base type should already be normalised.
      Parameters:
      a - media type
      b - base type, normalised
      Returns:
      true if b equals a or is a specialization of it, false otherwise
      Since:
      Apache Tika 1.2

    • getSupertype

      public MediaType getSupertype(MediaType type)
      Deprecated.
      Returns the supertype of the given type. If the media type database has an explicit inheritance rule for the type, then that is used. Next, if the given type has any parameters, then the respective base type (parameter-less) is returned. Otherwise built-in heuristics like text/... -> text/plain and .../...+xml -> application/xml are used. Finally application/octet-stream is returned for all types for which no other supertype is known, and the return value for application/octet-stream is null.
      Parameters:
      type - media type
      Returns:
      supertype, or null for application/octet-stream
      Since:
      Apache Tika 0.8
