Member Function Documentation

◆ __call()

XML_RPC2_CachedClient::__call	(	$methodName,
		$parameters
	)

__call Catchall

Encapsulate all the class logic :

determine if the cache has to be used (or not) for the called method
see if a cache is available for this call
if no cache available, really do the call and store the result for next time

Parameters

string	Method name
array	Parameters

Returns: mixed The call result, already decoded into native types
