Detailed Description

template<typename T>
class PSEvt::Proxy< T >

Interface class for type-safe proxy classes.

Proxy dictionary stores proxies of type ProxyI which are not type-safe (they work with void pointers). To make code safer this class implements ProxyI interface and introduces type-safe method to generate typed data. User-level interface should use this type instead of ProxyI.

This software was developed for the LCLS project. If you use all or part of it, please give an appropriate acknowledgment.

Member Function Documentation

template<typename T>

virtual boost::shared_ptr<void> PSEvt::Proxy< T >::getImpl	(	ProxyDictI *	dict,
		const Pds::Src &	source,
		const std::string &	key
	)			`[inline, protected, virtual]`

Get untyped object from the proxy.

The parameters passed to the proxy can be used by the proxy to find additional information from the same (or different) detector.

This is implementation of ProxyI interface which forwards call to the type-safe method getTypedImpl().

Parameters:

`[in]`	dict	Proxy dictionary containing this proxy.
`[in]`	source	Detector address information
`[in]`	key	String key, additional key supplied by user.

Returns:: Shared pointer of void type.

Implements PSEvt::ProxyI.
