      • Counter32

        public Counter32​(long value)
    • Method Detail

      • getSyntax

        public int getSyntax()
        Description copied from class: AbstractVariable
        Gets the ASN.1 syntax identifier value of this SNMP variable.
        Specified by:
        getSyntax in interface Variable
        Overrides:
        getSyntax in class UnsignedInteger32
        Returns:
        an integer value less than 128 for regular SMI objects and a value greater or equal than 128 for exception values like noSuchObject, noSuchInstance, and endOfMibView.
      • encodeBER

        public void encodeBER​(java.io.OutputStream outputStream)
                       throws java.io.IOException
        Description copied from class: AbstractVariable
        Encodes a Variable to an OutputStream.
        Specified by:
        encodeBER in interface BERSerializable
        Overrides:
        encodeBER in class UnsignedInteger32
        Parameters:
        outputStream - an OutputStream.
        Throws:
        java.io.IOException - if an error occurs while writing to the stream.
      • clone

        public java.lang.Object clone()
        Description copied from interface: Variable
        Clones this variable. Cloning can be used by the SNMP4J API to better support concurrency by creating a clone for internal processing. The content of this object is independent to the content of the clone. Thus, changes to the clone will have no effect to this object.
        Specified by:
        clone in interface Variable
        Overrides:
        clone in class UnsignedInteger32
        Returns:
        a new instance of this Variable with the same value.
      • increment

        public void increment()
        Increment the value of the counter by one. If the current value is 2^32-1 (4294967295) then value will be set to zero.
      • increment

        public long increment​(long increment)
        Increment the value by more than one in one step.
        Parameters:
        increment - an increment value greater than zero.
        Returns:
        the current value of the counter.
        Since:
        2.4.2
      • toSubIndex

        public OID toSubIndex​(boolean impliedLength)
        Description copied from class: AbstractVariable
        Converts the value of this Variable to a (sub-)index value.
        Specified by:
        toSubIndex in interface Variable
        Overrides:
        toSubIndex in class UnsignedInteger32
        Parameters:
        impliedLength - specifies if the sub-index has an implied length. This parameter applies to variable length variables only (e.g. OctetString and OID). For other variables it has no effect.
        Returns:
        an OID that represents this value as an (sub-)index.
      • fromSubIndex

        public void fromSubIndex​(OID subIndex,
                                 boolean impliedLength)
        Description copied from class: AbstractVariable
        Sets the value of this Variable from the supplied (sub-)index.
        Specified by:
        fromSubIndex in interface Variable
        Overrides:
        fromSubIndex in class UnsignedInteger32
        Parameters:
        subIndex - the sub-index OID.
        impliedLength - specifies if the sub-index has an implied length. This parameter applies to variable length variables only (e.g. OctetString and OID). For other variables it has no effect.
