Method Detail

values

public static NoOpCache[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (NoOpCache c : NoOpCache.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static NoOpCache valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

put

public void put(String id,
                Object value)

Description copied from interface: Cache

Adds or replaces a value in the cache.

Specified by:

put in interface Cache

Parameters:

id - The object id

value - The value to cache

get

public <T> T get(String id,
                 Function<? super String,T> mappingFunction)

Description copied from interface: Cache

Returns the value associated with the given id. If there is no association, the mapping function is used to calculate a value. This value will be stored in the cache.

Specified by:

get in interface Cache

Type Parameters:

T - the type of object to return from the cache

Parameters:

id - The object id

mappingFunction - The function to compute a value if the cache is not in the cache

Returns:

The value associated with given id

getIfPresent

public <T> T getIfPresent(String id)

Description copied from interface: Cache

Returns the value associated with the given id if it exists in the cache. If there is no association, null is returned.

Specified by:

getIfPresent in interface Cache

Type Parameters:

T - the type of object to return from the cache

Parameters:

id - The object id

Returns:

The value associated with given id

invalidate

public void invalidate(String id)

Description copied from interface: Cache

Invalidates the cache entry mapped to given id.

Specified by:

invalidate in interface Cache

invalidateAll

public void invalidateAll()

Description copied from interface: Cache

Invalidates all cache entries.

Specified by:

invalidateAll in interface Cache
