Method Details
-
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.
-
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.
-
getSyntax
public int getSyntax()Description copied from class:AbstractVariable
Gets the ASN.1 syntax identifier value of this SNMP variable.- Specified by:
getSyntax
in interfaceVariable
- Specified by:
getSyntax
in classAbstractVariable
- 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.
-
hashCode
public int hashCode()- Specified by:
hashCode
in interfaceVariable
- Specified by:
hashCode
in classAbstractVariable
-
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:
- the BER encoded length of this variable.
-
equals
- Specified by:
equals
in interfaceVariable
- Specified by:
equals
in classAbstractVariable
-
compareTo
- Specified by:
compareTo
in interfaceComparable<Variable>
- Specified by:
compareTo
in interfaceVariable
- Specified by:
compareTo
in classAbstractVariable
-
toString
Description copied from class:AbstractVariable
Gets a string representation of the variable.- Specified by:
toString
in interfaceVariable
- Specified by:
toString
in classAbstractVariable
- Returns:
- a string representation of the variable's value.
-
setValue
- Specified by:
setValue
in interfaceAssignableFromString
-
setValue
public final void setValue(int value) Sets the value of this integer.- Specified by:
setValue
in interfaceAssignableFromInteger
- Parameters:
value
- an integer value.
-
getValue
public final int getValue()Gets the value.- Returns:
- an integer.
-
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 final int toInt()Description copied from class:AbstractVariable
Returns an integer representation of this variable if such a representation exists.- Specified by:
toInt
in interfaceAssignableFromInteger
- 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 final 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.
