The filtering requirements in actual production are summarized in the following aspects:

The purpose of this article is to build a general filtering framework. This framework:

Process

Next, we will design an example to show you how to use it and provide a valuable role.

Assume there is a string: "123", "246", "B", "15", "16", "a32 ", we need to take out a group of substrings in this group of strings, which must meet the following requirements:

• If the original string list exists, take an integer of no less than 3.
• If the original string list exists, take two integers that contain 1.

According to the above requirements, the running result of our framework should be: "123", "15"

To analyze the above requirements, we need to build a custom filter using the following steps:

Gains

Abstract The common part, so that developers only focus on the business is a necessary factor in the existence of the framework. The filtering scheme proposed in this article is highly scalable. If you are interested, you can download the demo study.
