Interface CredentialsAgent

All Known Implementing Classes:

AbstractCredentialsAgent, CredentialsManager, JosmPreferencesCredentialAgent

public interface CredentialsAgent

A CredentialsAgent manages two credentials:

• the credential for Authenticator.RequestorType.SERVER which is equal to the OSM API credentials in JOSM
• the credential for Authenticator.RequestorType.PROXY which is equal to the credentials for an optional HTTP proxy server a user may use

In addition, it manages an OAuth Access Token for accessing the OSM server.

Method Summary

Modifier and Type	Method and Description
CredentialsAgentResponse	getCredentials(java.net.Authenticator.RequestorType requestorType, java.lang.String host, boolean noSuccessWithLastResponse)
java.awt.Component	getPreferencesDecorationPanel() Provide a Panel that is shown below the API password / username fields in the JOSM Preferences.
java.net.PasswordAuthentication	lookup(java.net.Authenticator.RequestorType requestorType, java.lang.String host) Looks up the credentials for a given type.
OAuthToken	lookupOAuthAccessToken() Lookup the current OAuth Access Token to access the OSM server.
void	store(java.net.Authenticator.RequestorType requestorType, java.lang.String host, java.net.PasswordAuthentication credentials) Saves the credentials in credentials for the given service type.
void	storeOAuthAccessToken(OAuthToken accessToken) Stores the OAuth Access Token accessToken.

Method Detail

lookup

java.net.PasswordAuthentication lookup(java.net.Authenticator.RequestorType requestorType,
                                       java.lang.String host)
                                throws CredentialsAgentException

Looks up the credentials for a given type.

Parameters:

requestorType - the type of service. Authenticator.RequestorType.SERVER for the OSM API server, Authenticator.RequestorType.PROXY for a proxy server

host - the hostname for these credentials

Returns:

the credentials

Throws:

CredentialsAgentException - thrown if a problem occurs in a implementation of this interface

store

void store(java.net.Authenticator.RequestorType requestorType,
           java.lang.String host,
           java.net.PasswordAuthentication credentials)
    throws CredentialsAgentException

Saves the credentials in credentials for the given service type.

Parameters:

requestorType - the type of service. Authenticator.RequestorType.SERVER for the OSM API server, Authenticator.RequestorType.PROXY for a proxy server

host - the hostname for these credentials

credentials - the credentials

Throws:

CredentialsAgentException - thrown if a problem occurs in a implementation of this interface

getCredentials

CredentialsAgentResponse getCredentials(java.net.Authenticator.RequestorType requestorType,
                                        java.lang.String host,
                                        boolean noSuccessWithLastResponse)
                                 throws CredentialsAgentException

Parameters:

requestorType - the type of service. Authenticator.RequestorType.SERVER for the OSM API server, Authenticator.RequestorType.PROXY for a proxy server

host - the hostname for these credentials

noSuccessWithLastResponse - true, if the last request with the supplied credentials failed; false otherwise. If true, implementations of this interface are advised to prompt the user for new credentials.

Throws:

CredentialsAgentException - thrown if a problem occurs in a implementation of this interface

lookupOAuthAccessToken

OAuthToken lookupOAuthAccessToken()
                           throws CredentialsAgentException

Lookup the current OAuth Access Token to access the OSM server. Replies null, if no Access Token is currently managed by this CredentialAgent.

Returns:

the current OAuth Access Token to access the OSM server.

Throws:

CredentialsAgentException - thrown if something goes wrong

storeOAuthAccessToken

void storeOAuthAccessToken(OAuthToken accessToken)
                    throws CredentialsAgentException

Stores the OAuth Access Token accessToken.

Parameters:

accessToken - the access Token. null, to remove the Access Token.

Throws:

CredentialsAgentException - thrown if something goes wrong

getPreferencesDecorationPanel

java.awt.Component getPreferencesDecorationPanel()

Provide a Panel that is shown below the API password / username fields in the JOSM Preferences. (E.g. a warning that password is saved unencrypted.)
