Examples of net.jini.security.ProxyPreparer

net.jini.security.ProxyPreparer
Performs operations on a newly unmarshalled remote proxy to prepare it for use. Typical operations include verifying trust in the proxy by calling {@link Security#verifyObjectTrust Security.verifyObjectTrust}, specifying constraints by calling {@link RemoteMethodControl#setConstraints RemoteMethodControl.setConstraints}, and granting the proxy permissions by calling {@link Security#grant Security.grant}.
Applications are expected to use instances of this class retrieved from a {@link Configuration} to prepare all remote proxies that they receive inorder to permit configuring how applications handle proxies. @author Sun Microsystems, Inc. @since 2.0
