Prefilter and postfilter plugins are very similar in concept; where they differ is in the execution -- more precisely the time of their execution.In terms of concept, both the prefilter and the postfilter plug-in are simple. The difference lies in their execution, more specifically their execution time (not a time period, but a time period ).

indices are decoded, then the decoder constructs the LPC synthesis filter. for every subframe, both the adaptive codebook excitation and fixed codebook excitation are decoded and input to the synthesis filter. the adaptive postfilter consists of A Formant and a forward-backward pitch postfilter. the excitation signal is input to the pitch postfilter, which in tu
This article describes the two annotations @PreFilter and @PostFilter . @PreFilter@PreFilter is used to filter the parameters of the method. In this case, the parameter is usually a collection type, and the qualifying value is persisted in the collection, and is removed from the collection that does not meet the criteria. If you have more than one parameter for the collection type, you need to use A property of the @PreFilter filtertarget to specify

C for the Pseudo class selector, an executive function is generated via the Setmatcher function, and the call to Setmatcher is followed by 6 parameters, namely Prefilter, selector, Matcher, Postfilter, Postfinder, Postselector.
Prefilter is the final function that was processed by the Elementmatcher function of the matchers array that was generated before the Setmatcher function was executed, Elementmatcher (matchers) Returns a new function that e

To apply a filter to an action, we need to overwrite the CController: filters () method. This method should return an array of filter configurations. For example:
class PostController extends CController{ ...... public function filters() { return array( 'postOnly + edit, create',
.
Custom filter instance:
"; return true; } /** * Performs the post-action filtering. * @param CFilterChain $filterChain the filter chain that the filter is on. */ protected function postFilter($filterChain) { echo "--->TestFilter.postFilter."; } }
Register the binding relationship between the custom filter and the action in the controller:

with filter. For example, an existing Filteraccesscontrol method defines a filter named AccessControl. The filter method must be of the following structure:
Public Function Filteraccesscontrol ($filterChain) { //calls $filterChain->run () to continue the execution of subsequent filters and actions. }
The $filterChain (filter chain) is an instance of Cfilterchain that represents the list of filters associated with the requested action. In the filter method, we can call $filterChain->run () to c

To customize the filter class, you must write a filter class separately, inherit from the CFilter class, and override some methods in the CFilter class. You can take a look at the CFilter class code, which is easy to understand.
Custom filter instance:
