Credentials have three different roles within JXTA: <ul> <li>Authentication credentials are associated with authentication methods and are used to provide information required for authentication. Each <A HREF="../../../net/jxta/credential/AuthenticationCredential.html" title="class in net.jxta.credential"><CODE>AuthenticationCredential</CODE></A> implementation is specific to its associated <A HREF="../../../net/jxta/membership/Authenticator.html" title="interface in net.jxta.membership"><CODE>Authenticator</CODE></A>. Authentication Credentials are normally created by constructing a document which follows a schema provided by the authentication method.</li> <li>Identity credentials associate an identity with a peer. The peer may request operations to be performed using that identity. Identity Credentials are created by successfully completing authentication with a Membership Service.</li> <li>Privledged operations associate an operation with an identity. To request a remote peer to perform some operation an application or service provides a <A HREF="../../../net/jxta/credential/PrivledgedOperation.html" title="interface in net.jxta.credential"><CODE>PrivledgedOperation</CODE></A> and an identity credential along with the request. The remote peer determines if the operation is permitted for the specified identity and if it is permitted, completes the operation.</li> </ul> <p/>The XML representation of a Credential uses the following very simple schema. Credential implementations extend this schema as needed. <p/><pre> <xs:complexType name="Cred"> <xs:all> </xs:all> </xs:complexType> </pre><P><P><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../net/jxta/document/StructuredDocument.html" title="interface in net.jxta.document">StructuredDocument</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../net/jxta/credential/Credential.html#getDocument(net.jxta.document.MimeMediaType)">getDocument</A></B>(<A HREF="../../../net/jxta/document/MimeMediaType.html" title="class in net.jxta.document">MimeMediaType</A> asMimeType)</CODE><BR> Write credential into a document. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../net/jxta/id/ID.html" title="class in net.jxta.id">ID</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../net/jxta/credential/Credential.html#getPeerGroupID()">getPeerGroupID</A></B>()</CODE><BR> Returns the peerGroupID associated with this credential</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../net/jxta/id/ID.html" title="class in net.jxta.id">ID</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../net/jxta/credential/Credential.html#getPeerID()">getPeerID</A></B>()</CODE><BR> Returns the peerID associated with this credential</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../net/jxta/service/Service.html" title="interface in net.jxta.service">Service</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../net/jxta/credential/Credential.html#getSourceService()">getSourceService</A></B>()</CODE><BR> Returns the service which generated this credential.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> java.lang.Object</CODE></FONT></TD><TD><CODE><B><A HREF="../../../net/jxta/credential/Credential.html#getSubject()">getSubject</A></B>()</CODE><BR> Returns the subject of this credential. </TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> boolean</CODE></FONT></TD><TD><CODE><B><A HREF="../../../net/jxta/credential/Credential.html#isExpired()">isExpired</A></B>()</CODE><BR> If true then the credential is expired. </TD>⌨️ 快捷键说明
