| PredictionService interface provides only one function GetPredictionList |
| which takes infos about previous words and current word (format details in |
| mojo/services/prediction/interfaces/prediction.mojom). |
| Connect to "mojo:prediction_service" to use the service. |
| |
| Description of each class: |
| res/main_en.dict.sha1 is the sha1 of main_en.dict (from Android |
| packages/inputmethods/LatinIME/java/res/raw/main_en.dict). |
| main_en.dict is the binary form of English dictionary |
| packages/inputmethods/LatinIME/dictionaries/en_wordlist.combined.gz |
| of the form |
| packages/inputmethods/LatinIME/java/src/com/android/inputmethod |
| /latin/makedict/FormatSpec.java. |
| |
| DictionaryService creates a latinime::DictionaryStructureWithBufferPolicy |
| from our dictionary file and prepares parameters (current word processed by |
| InputInfo) for getSuggestions if current word is not empty or getPredictions if |
| current word is empty (currently not working due to lack of ngram binary |
| dictionary) from latinime::DictionaryStructureWithBufferPolicy. After it |
| processes the prediction words array, it returns that to PredictionServiceImpl |
| which then returns back to the client. |
| |
| ProximityInfoFactory, TouchPositionCorrection and KeySet provide proximity |
| info of the keys. TouchPositionCorrection and KeySet are hardcoded English |
| QWERTY keyboard values because PredictionService can't get these keyboard |
| values from anywhere for now. |
| |
| TODO: |
| Add a bigram/ngram binary dictionary. Shouldn't need to change any other code |
| if the dictionary is of the same format as main_en.dict. If not, might need to |
| update third_party/android_prediction to the latest version. |
