All Implemented Interfaces:

ASN1Type, Cloneable

public class LSPLookup

extends ASN1OctetString

Represents a LSP_Lookup structure of the Location Service Protocol (LSP). Encapsulated in a LSPRequest it is sent to the Location Service Server (LSServer) or the Location Service Proxy (LSProxy) to request the contact address to a given implicit name. If successful, the LSPReply message transports a LSPLookupResult. This class is used by the Location Server Client (LSClient).

The ASN.1 structure of this request is as follows

 LSP_Lookup   ::= ImplicitName
 ImplicitName ::= OCTET STRING
 

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

Parameters:

implicitName - The implicit name.

Method Detail

createRequest

public static LSPLookup createRequest(byte[] code)
                               throws CorruptedCodeException,
                                      IllegalStateException,
                                      NullPointerException

Creates a new request from the given encoded request.

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).

getImplicitName

public byte[] getImplicitName()

Returns the implicit name.

Returns:

The implicit name.

getEncoded

public byte[] getEncoded()
                  throws IllegalStateException

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.
