Class DefaultAsnOctetsPrintable

java.lang.Object

uk.co.westhawk.snmp.stack.DefaultAsnOctetsPrintable

All Implemented Interfaces:

AsnOctetsPrintableFace

public class DefaultAsnOctetsPrintable
extends Object
implements AsnOctetsPrintableFace

Default implementation of AsnOctetsPrintableFace. This class has no effect on the way AsnOctets with type IPADDRESS or OPAQUE are printed.

When the type is ASN_OCTET_STR, the method tries to guess whether or not the string is printable; without the knowledge of the MIB it cannot distinguish between OctetString and any textual conventions, like DisplayString, InternationalDisplayString or DateAndTime.

Since:

4_14

Method Details

isPrintable

public boolean isPrintable(byte[] value)

Returns whether or not the AsnOctets' byte array represent a printable string or not.

This method can only make a rough guess. There is no way it always gets it right. It is much better to embed MIB knowledge in your implementation, and use toCalendar() or toDisplayString(), than calling toString().
