Package org.snmp4j.smi

Class GenericAddress

java.lang.Object
org.snmp4j.smi.AbstractVariable
org.snmp4j.smi.SMIAddress
org.snmp4j.smi.GenericAddress
All Implemented Interfaces:
Serializable, Cloneable, Comparable<Variable>, BERSerializable, Address, AssignableFromByteArray, AssignableFromString, Variable
public class GenericAddress extends SMIAddress
The GenericAddress implements the decorator and factory design pattern to provide a generic address type.

To register address types other than the default, set the system property ADDRESS_TYPES_PROPERTIES before calling the parse(java.lang.String) method for the first time.

    • setAddress

      public void setAddress(SMIAddress address)

    • getAddress

      public Address getAddress()

    • parse

      public static Address parse(String address)
      Parses a given transport protocol dependent address string into an Address instance that is subsumed by this GenericAddress object.
      Parameters:
      address - an address string with a leading type specifier as defined in the "address.properties". The format is "type:address" where the format of address depends on type. Valid values for type are, for example, "udp" and "tcp".
      Returns:
      a Address instance of the address classes specified in "address.properties" whose type ID matched the specified ID in address. If address cannot be parsed, null is returned.
      Throws:
      IllegalArgumentException - if the address type indicator supplied is not know.

    • parseAddress

      public boolean parseAddress(String address)
      Parse an address form the supplied string.
      Parameters:
      address - an address string known by the GenericAddress.
      Returns:
      boolean

    • setValue

      public void setValue(byte[] rawAddress)
      Description copied from interface: AssignableFromByteArray
      Sets the value of this object from the supplied byte array.
      Parameters:
      rawAddress - a byte array.

    • 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 int toInt()
      Description copied from class: AbstractVariable
      Returns an integer representation of this variable if such a representation exists.
      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 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.

    • toByteArray

      public byte[] toByteArray()
      Description copied from interface: AssignableFromByteArray
      Returns the value of this object as a byte array.
      Returns:
      a byte array.

    • setValue

      public void setValue(String value)
      Description copied from interface: Address
      Sets the address value from the supplied String. The string must match the format required for the Address instance implementing this interface. Otherwise an IllegalArgumentException runtime exception is thrown.
      Parameters:
      value - an address String.

    • getTDomainPrefix

      public static String getTDomainPrefix(Class<? extends Address> addressClass)
      Gets the transport domain prefix string (lowercase) for a supplied Address class.
      Parameters:
      addressClass - an implementation class of Address.
      Returns:
      the corresponding transport domain prefix as defined by the IANA registry "SNMP Transport Domains" if the addressClass has been registered with a domain prefix, null otherwise.
