Contents
Feature
A free reference, ensuring that the managing environment has always been entered when calling an object.
API
cppu/FreeReference.hxx template<class T> FreeReference FreeReference() {} FreeReference(cssuno::Reference<T> const & xRef) FreeReference(EnvAwareReference<T> const & rOther) cssuno::Reference<T> get() const throw (cssuno::RuntimeException) operator cssuno::Reference<T> () const throw (cssuno::RuntimeException) T * operator -> () const throw (cssuno::RuntimeException) bool is() const throw (cssuno::RuntimeException) void clear() FreeReference<T> & operator = (FreeReference<T> const & rOther) void set(cssuno::Reference<T> const & xRef) bool operator == (FreeReference const & rOther) const bool operator != (FreeReference const & rOther) const
Usage Example
#include <cppu/EnvGuards.hxx> ... { com::sun::star::uno::Reference<XFoo> ref(...) ... cppu::FreeReference<XFoo> free_xFoo(xFoo); cppu::EnvGuard otherEnv(cppu::Environment("just another env")); free_xFoo->doSomething(); // the free reference ensures that the correct environment etc. gets activated before invokation ... }
