get

public <T> CompletableFuture<Optional<T>> get(Object key,
                                              Argument<T> requiredType)

Description copied from interface: AsyncCache

Resolve the given value for the given key.

Specified by:

get in interface AsyncCache<io.lettuce.core.api.StatefulConnection<?,?>>

Type Parameters:

T - The concrete type

Parameters:

key - The cache key

requiredType - The required type

Returns:

An optional containing the value if it exists and is able to be converted to the specified type

get

public <T> CompletableFuture<T> get(Object key,
                                    Argument<T> requiredType,
                                    Supplier<T> supplier)

Description copied from interface: AsyncCache

Resolve the given value for the given key. If the value is not found the specified Supplier will be invoked and the return value cached.

Specified by:

get in interface AsyncCache<io.lettuce.core.api.StatefulConnection<?,?>>

Type Parameters:

T - The concrete type

Parameters:

key - The cache key

requiredType - The required type

supplier - The supplier that should be invoked if the value is not found

Returns:

An optional containing the value if it exists and is able to be converted to the specified type

putIfAbsent

public <T> CompletableFuture<Optional<T>> putIfAbsent(Object key,
                                                      T value)

Type Parameters:

T - The concrete type

Parameters:

key - The key with which the specified value is to be associated

value - The value to be associated with the specified key

Returns:

An optional of the existing value or Optional.empty() if the specified value parameter was cached

put

public CompletableFuture<Boolean> put(Object key,
                                      Object value)

Description copied from interface: AsyncCache
