	getRewindOffset ()
	Retrieves rewind offset, and then unsets it. More...

	prepare ($config, $context)
	Prepares the injector by giving it the config and context objects: this allows references to important variables to be made within the injector. More...

	checkNeeded ($config)
	This function checks if the HTML environment will work with the Injector: if p tags are not allowed, the Auto-Paragraphing injector should not be enabled. More...

	allowsElement ($name)
	Tests if the context node allows a certain element. More...

	handleText (&$token)
	Handler that is called when a text token is processed. More...

	handleElement (&$token)
	Handler that is called when a start or empty token is processed. More...

	handleEnd (&$token)
	Handler that is called when an end token is processed. More...

Protected Member Functions inherited from HTMLPurifier_Injector
	forward (&$i, &$current)
	Iterator function, which starts with the next token and continues until you reach the end of the input tokens. More...

	forwardUntilEndToken (&$i, &$current, &$nesting)
	Similar to _forward, but accepts a third parameter $nesting (which should be initialized at 0) and stops when we hit the end tag for the node $this->inputIndex starts in. More...
