.\" way too many mistakes in technical documents.

.SH "NAME"
"Net::Async::Tangence::Server" \- serve "Tangence" clients using "IO::Async"
.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This subclass of IO::Async::Listener accepts Tangence client
connections.
.SH "PARAMETERS"
.IX Header "PARAMETERS"
The following named parameters may be passed to \f(CW\*(C`new\*(C'\fR or \f(CW\*(C`configure\*(C'\fR:
.IP "registry => Tangence::Registry" 8
.IX Item "registry => Tangence::Registry"
The Tangence::Registry for the server's objects.
.SH "OVERRIDEABLE METHODS"
.IX Header "OVERRIDEABLE METHODS"
The following methods are provided but intended to be overridden if the
implementing class wishes to provide different behaviour from the default.
.SS "conn_rootobj"
.IX Subsection "conn_rootobj"
.Vb 1
\&   $rootobj = $server\->conn_rootobj( $conn, $identity )
.Ve
.PP
Invoked when a \f(CW\*(C`GETROOT\*(C'\fR message is received from the client, this method
should return a Tangence::Object as root object for the connection.
.PP
The default implementation will return the object with \s-1ID 1\s0; i.e. the first
object created in the registry.
.SS "conn_permits_registry"
.IX Subsection "conn_permits_registry"
.Vb 1
\&   $allow = $server\->conn_permits_registry( $conn )
.Ve
.PP
Invoked when a \f(CW\*(C`GETREGISTRY\*(C'\fR message is received from the client on the given
connection object. This method should return a boolean to indicate whether the
client is allowed to access the object registry.
.PP
The default implementation always permits this, but an overridden method may
decide to disallow it in some situations. When disabled, a client will not be
able to gain access to any serverside objects other than the root object, and
(recursively) any other objects returned by methods, events or properties on
objects already known. This can be used as a security mechanism.
