,Comparable<Variable>
,BERSerializable
,Address
,AssignableFromByteArray
,AssignableFromString
,Variable
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.

decodeBER
Description copied from class:AbstractVariable
Decodes aVariable
from anBERInputStream
.- Specified by:
decodeBER
in interfaceBERSerializable
- Specified by:
decodeBER
in classAbstractVariable
- Parameters:
inputStream
- anBERInputStream
containing a BER encoded byte stream.- Throws:
IOException
- if the stream could not be decoded by using BER rules.
-
encodeBER
Description copied from class:AbstractVariable
Encodes aVariable
to anOutputStream
.- Specified by:
encodeBER
in interfaceBERSerializable
- Specified by:
encodeBER
in classAbstractVariable
- Parameters:
outputStream
- anOutputStream
.- Throws:
IOException
- if an error occurs while writing to the stream.
-
getBERLength
public int getBERLength()Description copied from class:AbstractVariable
Returns the length of thisVariable
in bytes when encoded according to the Basic Encoding Rules (BER).- Specified by:
getBERLength
in interfaceBERSerializable
- Specified by:
getBERLength
in classAbstractVariable
- Returns:

-
setAddress
-
getAddress
-
parse
Parses a given transport protocol dependent address string into anAddress
instance that is subsumed by thisGenericAddress
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 ofaddress
depends ontype
. Valid values fortype
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 inaddress
. Ifaddress
cannot be parsed,null
is returned. - Throws:
IllegalArgumentException
- if the address type indicator supplied is not know.
-
parseAddress
Parse an address form the supplied string.- Parameters:
address
- an address string known by the GenericAddress.- Returns:
- boolean
- See Also:
-
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
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 interfaceVariable
- Specified by:
clone
in classAbstractVariable
- 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 interfaceVariable
- Specified by:
toInt
in classAbstractVariable
- 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 interfaceVariable
- Specified by:
toLong
in classAbstractVariable
- Returns:
- a long value.
-
toSubIndex
Description copied from class:AbstractVariable
Converts the value of thisVariable
to a (sub-)index value.- Specified by:
toSubIndex
in interfaceVariable
- Specified by:
toSubIndex
in classAbstractVariable
- Parameters:
impliedLength
- specifies if the sub-index has an implied length. This parameter applies to variable length variables only (e.g.OctetString
andOID
). For other variables it has no effect.- Returns:
- an OID that represents this value as an (sub-)index.
-
fromSubIndex
Description copied from class:AbstractVariable
Sets the value of thisVariable
from the supplied (sub-)index.- Specified by:
fromSubIndex
in interfaceVariable
- Specified by:
fromSubIndex
in classAbstractVariable
- 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
andOID
). 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
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 anIllegalArgumentException
runtime exception is thrown.- Parameters:
value
- an address String.
-
getFamily
Description copied from interface:Address
Gets the protocol family of this address.- Returns:
- a protocol family.
-
getSocketAddress
Description copied from interface:Address
Gets the socket address of this address.- Returns:
- the socket address representation (if available) of this address or
null
if that does not exist (yet).
-
getTDomainPrefix
Gets the transport domain prefix string (lowercase) for a suppliedAddress
class.- Parameters:
addressClass
- an implementation class ofAddress
.- 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. - Since:
- 2.0
-
newLocalAddress
Creates a new instance of the specified address type string (seeTYPE_UDP
for example) using its default constructor which creates an address usable as local address of an communication endpoint.- Parameters:
transportDomainPrefix
- a address type string like "udp", "tcp", "tls, "dtls", or "unix".- Returns:
- a new local address or
null
if the address type is unknown. - Throws:
RuntimeException
- if the address type is known but does not support local addresses (i.e., has no default constructor) or if it cannot be accessed.- Since:
- 3.7.1
-
