Class cApiCecRegistry

CEC registry class. Used to register chains and chain functions to invoke.

Following 3 types of CEC functions/callbacks are supported at the moment: - Callbacks, which should only be invoked. They don't return a value and have no break conditions, @see cApiCecHook::execute() - Callbacks, which should return a value and/or should modify a passed parameter,

Methods summary
`protected`	# `__construct( )` Constructor Constructor
`private`	# `__clone( )` Prevent cloning Prevent cloning
`public static cApiCecRegistry`	# `getInstance( )` Returns a instance of cApiCecRegistry Returns a instance of cApiCecRegistry Returns `cApiCecRegistry`
`public boolean`	# `addChainFunction( string $sChainName, string $sFunctionName )` Adds a chain function which is to invoke. Adds a chain function which is to invoke. Parameters `$sChainName` Chain name `$sFunctionName` Name of function/callback to invoke. Feasible values are: - "ClassName->methodName" to invoke a method of a ClassName instance. A instance of the clas will be created here. - "ClassName::methodName" to invoke a static method of ClassName. - "FunctionName" to invoke a function. NOTE: Necessary files must be manually included before or by defined autoloader. Returns boolean True on success, otherwhise false Throws `cInvalidArgumentException` if the given chain is not registered or the given callback is not callable
`public boolean`	# `chainFunctionExists( string $sChainName, string $sFunctionName )` Checks if a chain function exists. Checks if a chain function exists. Parameters `$sChainName` Chain name `$sFunctionName` Name of function to check Returns boolean
`public`	# `removeChainFunction( string $sChainName, string $sFunctionName )` Removes a chain function. Removes a chain function. Parameters `$sChainName` Chain name `$sFunctionName` Name of function to remove from chain.
`public cIterator`	# `getIterator( string $sChainName )` Returns the iterator for a desired chain. Returns the iterator for a desired chain. Parameters `$sChainName` Chain name Returns `cIterator` Todo : cIterator should be replaced by ArrayIterator (@see http://www.php.net/spl) but ArrayIterator uses rewind() instead of reset()...
`protected`	# `_resetIterator( string $sChainName )` Resets the chain iterator. Resets the chain iterator. Parameters `$sChainName`
`public`	# `flushAddedChains( )` Flushs added chains Flushs added chains
