Field Details

debug

public static int debug

Indicates the level of debug printed. By default this is none (0).

See Also:

• setDebug(int)

Constructor Details

AsnObject

public AsnObject()

Method Details

toString

public abstract String toString()

Returns a string representation of the object.

Overrides:

toString in class Object

Returns:

The string

setDebug

public static void setDebug(int newDebug)

Sets the new, global level of debug information for the stack package. The default value is zero, i.e. no debug info at all. All debug messages are printed to System.out.

The following messages will appear when debug is > (greater than):

• 0 - IOExceptions that won't be thrown to the user
• 1 - DecodingExceptions that won't be thrown to the user (received message with wrong SNMP version)
• 2 - DecodingExceptions when trying to decode traps
• 3 - processIncomingResponse errors: (corresponding Pdu cannot be found)
• 4 - Discovery of EngineId, Timeline
• 5 - Receiving traps, version/host do not correspond
• 6 - Pdu messages, sending etc
• 10 - Asn decoding of incoming messages
• 12 - Transmitter messages, Socket messages
• 15 - Not so important IOExceptions, like InterruptedIOException

Parameters:

newDebug - the new debug value

getRespType

public byte getRespType()

Returns the type of this Asn object, such as ASN_INTEGER or IPADDRESS. Note, the name of this method is deceiving; It has nothing (more) to do with a response.

Returns:

The AsnObject type.

See Also:

• getRespTypeString()
• SnmpConstants

getRespTypeString

public String getRespTypeString()

Returns the object type as string, such as "ASN_INTEGER" or "IPADDRESS". Note, the name of this method is deceiving; It has nothing (more) to do with a response.

Returns:

The AsnObject type.

• getRespType()
