All Implemented Interfaces:

Serializable, Cloneable, Iterable<ResponseType.Value>, Collection<ResponseType.Value>, Set<ResponseType.Value>

@NotThreadSafe
public class ResponseType
extends HashSet<ResponseType.Value>

Authorisation response type. Can be single-valued or multiple-valued.

The following helper methods can be used to find out the OAuth 2.0 protocol flow that a particular response type implies:

• impliesImplicitFlow()
• impliesCodeFlow()

Example response type implying an authorisation code flow:

 ResponseType() rt = new ResponseType();
 rt.add(ResponseType.Value.CODE);
 

Example response type from OpenID Connect specifying an ID token and an access token (implies implicit flow):

 ResponseType() rt = new ResponseType();
 rt.add(OIDCResponseTypeValue.ID_TOKEN);
 rt.add(ResponseType.Value.TOKEN);
 

Related specifications:

• OAuth 2.0 (RFC 6749), sections 3.1.1 and 4.1.1.
• OAuth 2.0 Multiple Response Type Encoding Practices.

Constructor Detail

ResponseType

public ResponseType()

Creates a new empty response type.

ResponseType

public ResponseType(String... values)

Creates a new response type with the specified string values.

Parameters:

values - The string values. Must not be null.

ResponseType

public ResponseType(ResponseType.Value... values)

Creates a new response type with the specified values.

Parameters:

values - The values. Must not be null.

Method Detail

getDefault

public static ResponseType getDefault()

Gets the default response type.

Returns:

The default response type, consisting of the value ResponseType.Value.CODE.

parse

public static ResponseType parse(String s)
                          throws ParseException

Parses a set of authorisation response types.

Example serialised response type sets:

 code
 token
 id_token
 id_token token
 code token
 code id_token
 code id_token token
 

Parameters:

s - Space-delimited list of one or more authorisation response types.

Returns:

The authorisation response types set.

Throws:

ParseException - If the parsed string is null or empty.

impliesCodeFlow

public boolean impliesCodeFlow()

Returns true if this response type implies a code flow. This is determined by the presence of a code value.

Returns:

true if a code flow is implied, else false.

impliesImplicitFlow

public boolean impliesImplicitFlow()

Returns true if this response type implies an implicit flow. This is determined by the absence of a code value.

Returns:

true if an implicit flow is implied, else false.

contains

public boolean contains(String value)

Checks if this response type contains the specified string value.

Parameters:

value - The string value. Must not be null.

Returns:

true if the value is contained, else false.

toString

public String toString()

Returns the string representation of this authorisation response type.

Example serialised response types:

 code
 token
 id_token
 id_token token
 code token
 code id_token
 code id_token token
 

Overrides:

toString in class AbstractCollection<ResponseType.Value>

Returns:

Space delimited string representing the authorisation response type.
