Detailed Description

This class manages the access of local Expression Corba Servants and Servers.

Especially, it also takes care of the copy/clone semantics and informs the servants when a DataSource copy() operation changed the location of a DataSource it was using.

Member Function Documentation

static void RTT::Corba::ExpressionServer::CleanupExpressions

(

)

[static]

Removes all cached Expression servers.

Any future client call to such a server will result in a CORBA exception.

static void RTT::Corba::ExpressionServer::copy

(

std::map< const DataSourceBase *, DataSourceBase * > &

alreadyCloned

)

[static]

This method informs the servants that a new DataSource needs to be used because of a copy operation.

It also updates the internal maps such that each new lookup will resolve to the new DataSource instead of the old. The old DataSource becomes 'unserved' and may thus become available for clean-up.

static Corba::Expression_ptr RTT::Corba::ExpressionServer::CreateAssignableExpression	(	DataSourceBase::shared_ptr	expr,
		PortableServer::POA_ptr	p
	)			[static]

Factory method: create a CORBA server to an assignable expression.

Parameters:

expr

The expression to serve

Returns:

A new or previously created CORBA server for expr.

static Corba::Expression_ptr RTT::Corba::ExpressionServer::CreateExpression	(	DataSourceBase::shared_ptr	expr,
		PortableServer::POA_ptr	p
	)			[static]

Factory method: create a CORBA server to an expression.

Parameters:

expr

The expression to serve

Returns:

A new or previously created CORBA server for expr.

static Corba::Method_ptr RTT::Corba::ExpressionServer::CreateMethod	(	DataSourceBase::shared_ptr	expr,
		MethodC *	orig,
		PortableServer::POA_ptr	p
	)			[static]

Factory method: create a CORBA server to a method.

Parameters:

expr

The expression to serve

Returns:

A new or previously created CORBA server for expr.
