TieredCache class

Tiered implementation of the Cache interface allowing the assignement of a primary and secondary caches. It was designed to be used with a primary Cache bound to a fast CacheStore and a secondary cache bound to a persistent CacheStore implementation

Constructors

TieredCache(Cache _primary, Cache _secondary)

Builds a TieredCache with a primary and a secondary cache

Properties

hashCode → int

The hash code for this object.

no setter, inherited

keys → Future<Iterable<String>>

Returns a Iterable over all the Cache keys

no setter, override

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

size → Future<int>

The number of entries on the cache

no setter, override

Methods

clear() → Future<void>

Clears the contents of the cache

override

containsKey(String key) → Future<bool>

Determines if the Cache contains an entry for the specified key.

override

get(String key, {Duration? expiryDuration}) → Future

Returns the cache value for the specified key. If specified expiryDuration is used instead of the configured expiry policy duration

override

getAndPut(String key, dynamic value, {Duration? expiryDuration}) → Future

Associates the specified value with the specified key in this cache, returning an existing value if one existed. If the cache previously contained a mapping for the key, the old value is replaced by the specified value

override

getAndRemove(String key) → Future

Removes the entry for a key only if currently mapped to some value.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

on<T extends CacheEvent>() → Stream<T>

Listens for events of Type T and its subtypes.

override

put(String key, dynamic value, {Duration? expiryDuration}) → Future<void>

Add / Replace the cache value for the specified key. If specified expiryDuration is used instead of the configured expiry policy duration

override

putIfAbsent(String key, dynamic value, {Duration? expiryDuration}) → Future<bool>

Associates the specified key with the given value if not already associated with a value.

override

remove(String key) → Future<void>

Removes the mapping for a key from this cache if it is present.

override

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.

inherited

operator [](String key) → Future

Get the cache value for the specified key.
