Interface UnitValue

  • All Superinterfaces:

    public interface UnitValue
    extends GroupedAvp
    Defines an interface representing the Unit-Value grouped AVP type. From the Diameter Credit-Control Application (rfc4006.txt) specification:
     8.8.  Unit-Value AVP
     
        Unit-Value AVP is of type Grouped (AVP Code 445) and specifies the
        units as decimal value.  The Unit-Value is a value with an exponent;
        i.e., Unit-Value = Value-Digits AVP * 10^Exponent.  This
        representation avoids unwanted rounding off.  For example, the value
        of 2,3 is represented as Value-Digits = 23 and Exponent = -1.  The
        absence of the exponent part MUST be interpreted as an exponent equal
        to zero.
     
        It is defined as follows (per the grouped-avp-def of
        RFC 3588 [DIAMBASE]):
     
                         Unit-Value ::= < AVP Header: 445 >
                                        { Value-Digits }
                                        [ Exponent ]
     
    Note:
    The support for extension AVPs is present even thou the ABNF grammar for this AVP does not contain the "* [ AVP ]" line. Be aware that adding any extension AVPs may result in interoperability problems with products that strongly validate the incoming diameter message for it's adherence to the specification.
    • Method Detail

      • hasValueDigits

        boolean hasValueDigits()
        Returns true if the Value-Digits AVP is present in the Unit-Value AVP.
      • getValueDigits

        long getValueDigits()
        Returns the value of the Value-Digits AVP, of type Integer64. Use hasValueDigits() to check the existence of this AVP.
        Returns:
        the value of the Value-Digits AVP
        Throws:
        IllegalStateException - if the Value-Digits AVP has not been set.
      • setValueDigits

        void setValueDigits​(long valueDigits)
        Sets the value of the Value-Digits AVP, of type Integer64.
      • removeValueDigits

        void removeValueDigits()
        Removes the Value-Digits AVP from the Unit-Value AVP. If the Value-Digits AVP is not present, this method returns silently.
      • hasExponent

        boolean hasExponent()
        Returns true if the Exponent AVP is present in the Unit-Value AVP.
      • getExponent

        int getExponent()
        Returns the value of the Exponent AVP, of type Integer32. Use hasExponent() to check the existence of this AVP.
        Returns:
        the value of the Exponent AVP
        Throws:
        IllegalStateException - if the Exponent AVP has not been set.
      • setExponent

        void setExponent​(int exponent)
        Sets the value of the Exponent AVP, of type Integer32.
      • removeExponent

        void removeExponent()
        Removes the Exponent AVP from the Unit-Value AVP. If the Exponent AVP is not present, this method returns silently.
      • getExtensionAvps

        DiameterAvp[] getExtensionAvps()
        Returns the set of extension AVPs. The returned array contains the extension AVPs in the order they appear in the Unit-Value AVP. A return value of null implies that no extensions AVPs have been set.
      • setExtensionAvps

        void setExtensionAvps​(DiameterAvp[] avps)
                       throws AvpNotAllowedException
        Sets the set of extension AVPs with all the values in the given array. The AVPs will be added to Unit-Value AVP in the order in which they appear in the array. Note: the array must not be altered by the caller following this call, and getExtensionAvps() is not guaranteed to return the same array instance, e.g. an "==" check would fail.
        Throws:
        AvpNotAllowedException - if an AVP is encountered of a type already known to this class (i.e. an AVP for which get/set methods already appear in this class)
        NullPointerException - if avps is null.
      • removeExtensionAvps

        void removeExtensionAvps()
        Removes all extension AVPs from the Unit-Value AVP. If no extension AVPs are present, this method returns silently.
