Method Detail

getSecurityParametersPosition

public int getSecurityParametersPosition()

Description copied from interface: SecurityParameters

Gets the byte position of the first byte (counted from zero) of the security parameters in the whole message.

Specified by:

getSecurityParametersPosition in interface SecurityParameters

Returns:

the position of the first byte (counted from zero) of the security parameters in the whole SNMP message. -1 is returned, when the position is unknown (not set).

setSecurityParametersPosition

public void setSecurityParametersPosition(int pos)

Description copied from interface: SecurityParameters

Sets the position of the first byte (counted from zero) of the security parameters in the whole SNMP message.

Specified by:

setSecurityParametersPosition in interface SecurityParameters

Parameters:

pos - an integer value greater or equal than zero.

getBERMaxLength

public int getBERMaxLength(int securityLevel)

Description copied from interface: SecurityParameters

Gets the maximum length of the BER encoded representation of this SecurityParameters instance.

Specified by:

getBERMaxLength in interface SecurityParameters

Parameters:

securityLevel - the security level to be used.

Returns:

the maximum BER encoded length in bytes.

decodeBER

public void decodeBER(BERInputStream inputStream)
               throws java.io.IOException

Description copied from class: AbstractVariable

Decodes a Variable from an BERInputStream.

Specified by:

decodeBER in interface BERSerializable

Overrides:

decodeBER in class OctetString

Parameters:

inputStream - an BERInputStream containing a BER encoded byte stream.

Throws:

java.io.IOException - if the stream could not be decoded by using BER rules.

getScopedPduPosition

public int getScopedPduPosition()

Gets the position of the ScopedPDU.

Returns:

the start position in the BERInputStream.
