All Implemented Interfaces:

ASN1Type, Cloneable

public class LSPList

extends ASN1Integer

Represents a LSP_List 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 all modified entries since a specified time. If successful, the LSPReply message transports a LSPListResult structure. This class can be used by an adminisration GUI to represent the current state of the LSServer and LSProxy.

The ASN.1 structure of this request is as follows

 LSP_List  ::= Timestamp
 Timestamp ::= INTEGER
 

The timestamp represents the time in milliseconds since since January 1, 1970, 00:00:00 GMT.

Constructor Detail

LSPList

public LSPList()

Creates an instance ready for decoding.

LSPList

public LSPList(long timestamp)

Parameters:

timestamp - The time in milliseconds.

Method Detail

createRequest

public static LSPList 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).

getTimestamp

public long getTimestamp()

Returns the timestamp in milliseconds since January 1, 1970, 00:00:00 GMT.

Returns:

The timestamp.

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.
