* A specific filter implementation tailored for MyMemory services. |

15
|
|
|
* This class extends the base `AbstractFilter` to provide custom, client-specific |

16

|
|
* filtering logic by dynamically modifying the transformation pipeline. It is designed |

17

|
|
|
* clients (such as Airbnb, Roblox, etc.). |

19
|
|
|
* |
|
20
|
|
|
* It uses a Client ID (`cid`) passed during the transformation to adjust the |
|
21
|
|
|
* pipeline on the fly, ensuring the correct set of handlers is used for each case. |
