Usage

Create a cache instance

Kache provides a simple DSL to create cache instance.

Create a cache instance with default policy LRU and capacity 128:

val cache: Kache<Int, String> = Builder.build()

Create a FIFO cache instance with capacity of 32:

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

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()
