Yes, also like any `Map`. 47 | 48 | Key is the same you put this file into cache 49 | 50 | This method will return `File` you put into cache or `null`, if file was evicted from cache. 51 | 52 | ```java 53 | String key = "some-key"; 54 | File file = cache.get(key); 55 | ``` 56 | 57 | ### Delete file from cache 58 | To delete file from cache, just invoke `delete` method. 59 | 60 | Key is the same you put this file into cache 61 | 62 | File will be deleted from cache and from journal. 63 | 64 | ```java 65 | String key = "some-key"; 66 | cache.delete(key); 67 | ``` 68 | 69 | ### Clear cache 70 | Sometime you may need to clear whole cache and drop all stored files. 71 | 72 | ```java 73 | cache().clearCache(); 74 | ``` 75 | 76 | ### List keys in cache 77 | To get all keys, managed by cache, invoke `keySet()` method. 78 | 79 | This will return `Set`. 80 | 81 | List all keys in cache may be useful to check all files, stored in cache. 82 | 83 | ```java 84 | Set keys = cache.keySet(); 85 | ``` 86 | 87 | 88 | ### Get cache status information 89 | There are some useful cache status information, that you can request. 90 | 91 | ```java 92 | cache.getCacheSize(); // Cache size in bytes, that you set up on cache creation. 93 | cache.getUsedSpace(); // Size of all files, stored in cache. 94 | cache.getFreeSpace(); // Free size in cache. 95 | cache.getJournalSize(); // Internal cache journal size in bytes. 96 | ``` 97 | 98 | 99 | ### License 100 | MIT License 101 | 102 | Copyright (c) 2022 Igor Solkin 103 | 104 | Permission is hereby granted, free of charge, to any person obtaining a copy 105 | of this software and associated documentation files (the "Software"), to deal 106 | in the Software without restriction, including without limitation the rights 107 | to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 108 | copies of the Software, and to permit persons to whom the Software is 109 | furnished to do so, subject to the following conditions: 110 | 111 | The above copyright notice and this permission notice shall be included in all 112 | copies or substantial portions of the Software. 113 | 114 | THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 115 | IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 116 | FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
