```
public class ServiceLocator
extends V3Extension
```
This class implements the OCSP ServiceLocator (CRL References) extension.
As with all OCSP extensions, support of the ServiceLocator extension is optional for client and servers. The critical flag should not be set.
Each OCSP extension is associated with a specific ocsp extension object identifier, derived from RFC 2560:
```
 id-pkix  OBJECT IDENTIFIER  ::=
        { iso(1) identified-organization(3) dod(6) internet(1)
          security(5) mechanisms(5) pkix(7) }

 id-ad OBJECT IDENTIFIER ::= { id-pkix 48 }       
        -- arc for access descriptors

 id-ad-ocsp      OBJECT IDENTIFIER ::= { id-ad 1 }
 
 id-pkix-ocsp    OBJECT IDENTIFIER ::= { id-ad-ocsp }
 
```
The object identifier for the ServiceLocator extension is defined as:
```
 id-pkix-ocsp-service-locator  OBJECT IDENTIFIER ::= { id-pkix-ocsp 7 }
 
```
which corresponds to the OID string "1.3.6.1.5.5.7.48.1.7".
The Online Certificate Status Protocol (RFC 2560) specifies the ServiceLocator extension for allowing a server to support forwarding of received request to the OCSP server which is known to be authoritative for the identified certificate. For this purpose the ServiceLocator extension my be included as one of the singleRequestExtensions in requests.
ASN.1 definition:
```
 ServiceLocator ::= SEQUENCE {
     issuer    Name,
     locator   AuthorityInfoAccessSyntax OPTIONAL }
 
```
Values for these fields are obtained from the corresponding fields in the subject certificate.
For adding a ServiceLocator extension object to a Request, use the addExtension method, e.g.:
```
 Name issuer = cert.getIssuerDN();
 AuthorityInfoAccess locator = (AuthorityInfoAccess)cert.getExtension(AuthorityInfoAccess.oid);
 ServiceLocator serviceLocator = new ServiceLocator(issuer);
 serviceLocator.setLocator(locator);
 request.addExtension(serviceLocator);
 
```

- Field Detail
  - oid
```
public static final ObjectID oid

- Constructor Detail
  - ServiceLocator
```
public ServiceLocator()
```
    Default constructor. Used for dynamic object creation.
  - ServiceLocator
```
public ServiceLocator(Name issuer)
```
    Creates a ServiceLocator extension from the given issuer name.
    
    Parameters:
    
    issuer - the name of the issuer
- Method Detail
  - setIssuer
```
public void setIssuer(Name issuer)
```
    Sets the issuer name of this ServiceLocator extension.
    
    Parameters:
    
    issuer - the name of the issuer
  - getIssuer
```
public Name getIssuer()
```
    Gets the issuer name of this ServiceLocator extension.
    
    Returns:
    
    the name of the issuer
  - setLocator
```
public void setLocator(AuthorityInfoAccess locator)
```
    Stets the locator.
    
    Parameters:
    
    locator - the locator AuthorityInfoAccess specifying the authorized responder of the certificate in mind
  - getLocator
```
public AuthorityInfoAccess getLocator()
```
    Gets the locator.
    
    Returns:
    
    the locator AuthorityInfoAccess specifying the authorized responder of the certificate in mind
  - getObjectID
```
public ObjectID getObjectID()
```
    Returns the object ID of this ServiceLocator extension
    
    Specified by:
    
    getObjectID in class V3Extension
    
    Returns:
    
    the object ID
  - init
```
public void init(ASN1Object obj)
          throws X509ExtensionException
```
    Inits this ServiceLocator implementation with an ASN1object representing the value of this extension.
    The given ASN1Object is the one created by toASN1Object().
    This method is used by the X509Extensions class when parsing the ASN.1 representation of a OCSP object for properly initializing an included ServiceLocator extension. This method initializes the extension only with its value, but not with its critical specification. For that reason, this method shall not be explicitly called by an application.
    The ASN1Object supplied to this method will reflect the ASN.1 representation of the ServiceLocator extension value:
```
 ServiceLocator ::= SEQUENCE {
     issuer    Name,
     locator   AuthorityInfoAccessSyntax OPTIONAL }
 
```
    Specified by:
    
    init in class V3Extension
    
    Parameters:
    
    obj - the ServiceLocator as ASN1Object (SEQUENCE)
    
    Throws:
    
    X509ExtensionException - if the extension cannot be initialized from its ASN1 representation
  - toASN1Object
```
public ASN1Object toASN1Object()
                        throws X509ExtensionException
```
    Returns an ASN1Object representing the value of this ServiceLocator extension.
    The ASN1Object returned by this method will reflect the ASN.1 representation of the ServiceLocator extension value:
```
 ServiceLocator ::= SEQUENCE {
     issuer    Name,
     locator   AuthorityInfoAccessSyntax OPTIONAL }
 
```
    Specified by:
    
    toASN1Object in class V3Extension
    
    Returns:
    
    the value of this ServiceLocator as ASN1Object (SEQUENCE)
    
    Throws:
    
    X509ExtensionException - if the extension could not be created
  - hashCode
```
public int hashCode()
```
    Returns a hashcode for this identity.
    
    Specified by:
    
    hashCode in class V3Extension
    
    Returns:
    
    a hash code for this identity
  - toString
```
public java.lang.String toString()
```
    Returns a string that represents the contents of this ServiceLocator extension.
    
    Overrides:
    
    toString in class java.lang.Object
    
    Returns:
    
    the string representation
