    • hashCode

      public int hashCode()
      Specified by:
      hashCode in interface Variable

      public int getBERLength()
      Description copied from class: AbstractVariable
      Returns the length of this Variable in bytes when encoded according to the Basic Encoding Rules (BER).
      Specified by:
      getBERLength in interface BERSerializable
      Specified by:

      Returns:
      the BER encoded length of this variable.

    • equals

      public boolean equals(Object o)
      Specified by:
      equals in interface Variable
      Specified by:
      equals in class AbstractVariable

    • compareTo

      public int compareTo(Variable o)
      Specified by:
      compareTo in interface Comparable<Variable>
      Specified by:
      compareTo in interface Variable
      Specified by:
      compareTo in class AbstractVariable

    • toString

      public String toString()
      Description copied from class: AbstractVariable
      Gets a string representation of the variable.
      Specified by:
      toString in interface Variable
      Specified by:
      toString in class AbstractVariable
      Returns:

    • setValue

      public final void setValue(String value)
      Specified by:
      setValue in interface AssignableFromString

    • setValue

      public final void setValue(int value)
      Sets the value of this integer.

      setValue in interface AssignableFromInteger
      Parameters:
      value - an integer value.

    • getValue

      public final int getValue()
      Gets the value.
      Returns:
      an integer.

    • clone

      public 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
      Specified by:
      clone in class AbstractVariable
      Returns:
      a new instance of this Variable with the same value.

    • toInt

      public final int toInt()
      Description copied from class: AbstractVariable
      Returns an integer representation of this variable if such a representation exists.
      Specified by:
      toInt in interface AssignableFromInteger
      Specified by:
      toInt in interface Variable
      Specified by:
      toInt in class AbstractVariable
      Returns:
      an integer value (if the native representation of this variable would be a long, then the long value will be casted to int).

    • toLong

      public final long toLong()
      Description copied from class: AbstractVariable
      Returns a long representation of this variable if such a representation exists.
      Specified by:
      toLong in interface Variable
      Specified by:
      toLong in class AbstractVariable
      Returns:
      a long value.

    • 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
      Specified by:
      toSubIndex in class AbstractVariable
      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
      Specified by:
      fromSubIndex in class AbstractVariable
      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.
