All Implemented Interfaces:

public class LSPProxyInvalidate

extends ASN1OctetString

Represents a LSP_ProxyInvalidate structure of the Location Service Protocol (LSP). Encapsulated in a LSPRequest it is sent to the Location Service Proxy (LSProxy) to invalidate an existing entry with the given implicit name. If successful, the LSPReply message has the reply state ACKNOWLEDGE. This class is used by the Location Server Client (LSClient) to inform the LSProxy of mobile objects, which leave the current LAN.

The ASN.1 structure of this request is as follows

 LSP_ProxyInvalidate ::= ImplicitName
 ImplicitName        ::= OCTET STRING
 

The implicit name is the unique identifier of an mobile object for instance the hashcode of its static part.

Parameters:

code - The encoded request.

Returns:

The decoded request.

Throws:

CorruptedCodeException - if the code is bad.

IllegalStateException - if an error occurs while decoding with DERDecoder (RuntimeException).

NullPointerException - if code is null (RuntimeException).

Returns the DER encoded request.

Returns:

The encoded request.

Throws:

IllegalStateException - if an exception occures during ASN1 encoding (RuntimeException).

toString

public String toString()

Returns the string representation of this request. This is done in following manner

 ASN1StructureName {
 Property  : Value
 }
 

Returns:

The string representation.
