uk.co.westhawk.examplev2c.DisplayString

All Implemented Interfaces:

java.awt.event.ActionListener, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, java.util.EventListener, java.util.Observer, AsnOctetsPrintableFace

public class DisplayString
extends javax.swing.JComponent
implements java.util.Observer, java.awt.event.ActionListener, AsnOctetsPrintableFace

The DisplayString application tests the display (print) of DisplayString. It will display the parameters, as configured in the properties file. It will show the (unicode) value as specified in the properties file in the UI. The UI will enable you to do a set with this value. The returned value should be exactly the same as original unicode one.

The name of the properties file can be passed as first argument to this application. If there is no such argument, it will look for DisplayString.properties. If this file does not exist, the application will use default parameters.

The user can set the required OID and perform a Get or GetNext request.

The user can also set a MIB variable by performing a Set request. By default the value is set as a String type (using AsnOctets), unless the value is a number (AsnInteger will then be used).

Method Detail

init

public void init()

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent evt)

isPrintable

public boolean isPrintable(byte[] value)

See Also:

AsnOctets.toCalendar(), AsnOctets.toDisplayString(), AsnOctets.toHex(), AsnOctets.toString()

toInternationalDisplayString

public java.lang.String toInternationalDisplayString(byte[] value)

Description copied from interface: AsnOctetsPrintableFace

This method provides the implemantation of the InternationalDisplayString text-convention. See HOST-RESOURCES-MIB.

"This data type is used to model textual information in some character set. A network management station should use a local algorithm to determine which character set is in use and how it should be displayed. Note that this character set may be encoded with more than one octet per symbol, but will most often be NVT ASCII. When a size clause is specified for an object of this type, the size refers to the length in octets, not the number of symbols."

Specified by:

toInternationalDisplayString in interface AsnOctetsPrintableFace

update
