Method Detail

LengthBytes

public int LengthBytes(int length)

Returns length field size for a packet length

Parameters:

length - Length of data to see if it fits in packet.

AsnBuildHeader

public void AsnBuildHeader(java.io.OutputStream out,
                           byte type,
                           int length)
                    throws java.io.IOException

Encode ASN header

Parameters:

out - Output stream

type - Type

length - Length

AsnMakeMe

public AsnObject AsnMakeMe(java.io.InputStream in,
                           byte type)
                    throws java.io.IOException

Build an ASN.1 PDU.

Parameters:

in - Input stream

type - SNMP Pdu or data type

AsnReadHeader

public AsnObject AsnReadHeader(java.io.InputStream in)
                        throws java.io.IOException

Retrieve the ASN header from the input stream.

Parameters:

in - Input stream

Returns:

Header ASN object

write

public abstract void write(java.io.OutputStream out)
                    throws java.io.IOException

size

public int size()

add

public AsnObject add(AsnObject child)

Add a child to the sequence

Parameters:

child - An ASN object to the child

Returns:

The child

findPdu

public AsnObject findPdu()

Recursively look for a pduSequence object. If not overridden - then not a sequence -

Returns:

A PduSequence object.
