:
val fifoCache: Kache<Int, String> = Builder.build {
policy = FIFO
capacity = 32
}
Create a LRU cache with capacity 1024
val lruCache: Kache<Int, String> = Builder.build {
policy = LRU
capacity = 1024
}
Supported parameters
NAME | TYPE | VALUE |
---|---|---|
policy | Policy | FIFO for first in first out cache, or LRU for least recently used cache. |
capacity | Int | The maximum size of the cache. |
Cache operations
Put an entry in the cache:
cache.put(1, "Hello") // [1 to "Hello"]
cache.put(2, "World") // [1 to "Hello", 2 to "World"]
Get an entry from the cache:
cache.get(1) // return the value "Hello"
Check the key :
cache.put(2, "World")
cache.exists(2) // return true
Return null if the key does not exist.
cache.get(4) // return null
Remove an entry from the cache:
cache.remove(1) // remove the entry then return the removed value "Hello"
Clear the cache:
cache.clear()
