When overridden in a derived class, inserts a cache entry into the cache.
Overloads
Set(CacheItem, CacheItemPolicy) |
When overridden in a derived class, inserts the cache entry into the cache as a CacheItem instance, specifying information about how the entry will be evicted. |
Set(String, Object, DateTimeOffset, String) |
When overridden in a derived class, inserts a cache entry into the cache, specifying time-based expiration details. |
Set(String, Object, CacheItemPolicy, String) |
When overridden in a derived class, inserts a cache entry into the cache. |
Remarks
The typical behavior of the Set overload methods is an insert-or-update operation. A cache entry is either inserted as a new entry if the specified entry does not exist, or the cache entry is updated with a new value if it already exists.
Set(CacheItem, CacheItemPolicy)
- Source:
- ObjectCache.cs
- Source:
- ObjectCache.cs
When overridden in a derived class, inserts the cache entry into the cache as a CacheItem instance, specifying information about how the entry will be evicted.
public:
abstract void Set(System::Runtime::Caching::CacheItem ^ item, System::Runtime::Caching::CacheItemPolicy ^ policy);
public abstract void Set (System.Runtime.Caching.CacheItem item, System.Runtime.Caching.CacheItemPolicy policy);
abstract member Set : System.Runtime.Caching.CacheItem * System.Runtime.Caching.CacheItemPolicy -> unit
Public MustOverride Sub Set (item As CacheItem, policy As CacheItemPolicy)
Parameters
- item
- CacheItem
The cache item to add.
- policy
- CacheItemPolicy
An object that contains eviction details for the cache entry. This object provides more options for eviction than a simple absolute expiration.
Remarks
If the key for item
does not exist, item
is inserted as a new cache entry. If an item with a key that matches item
exists, the value from item
is used to update or overwrite the value of the existing cache entry.
Applies to
Set(String, Object, DateTimeOffset, String)
- Source:
- ObjectCache.cs
- Source:
- ObjectCache.cs
When overridden in a derived class, inserts a cache entry into the cache, specifying time-based expiration details.
public abstract void Set (string key, object value, DateTimeOffset absoluteExpiration, string regionName = default);
abstract member Set : string * obj * DateTimeOffset * string -> unit
Public MustOverride Sub Set (key As String, value As Object, absoluteExpiration As DateTimeOffset, Optional regionName As String = Nothing)
Parameters
- key
- String
A unique identifier for the cache entry.
- value
- Object
The object to insert.
- absoluteExpiration
- DateTimeOffset
The fixed date and time at which the cache entry will expire.
- regionName
- String
Optional. A named region in the cache to which the cache entry can be added, if regions are implemented. The default value for the optional parameter is null
.
Remarks
If an item that matches key
does not exist in the cache, value
and key
are used to insert as a new cache entry. If an item with a key that matches item
exists, the cache entry is updated or overwritten by using value
.
Applies to
Set(String, Object, CacheItemPolicy, String)
- Source:
- ObjectCache.cs
- Source:
- ObjectCache.cs
When overridden in a derived class, inserts a cache entry into the cache.
public abstract void Set (string key, object value, System.Runtime.Caching.CacheItemPolicy policy, string regionName = default);
abstract member Set : string * obj * System.Runtime.Caching.CacheItemPolicy * string -> unit
Public MustOverride Sub Set (key As String, value As Object, policy As CacheItemPolicy, Optional regionName As String = Nothing)
Parameters
- key
- String
A unique identifier for the cache entry.
- value
- Object
The object to insert.
- policy
- CacheItemPolicy
An object that contains eviction details for the cache entry. This object provides more options for eviction than a simple absolute expiration.
- regionName
- String
Optional. A named region in the cache to which the cache entry can be added, if regions are implemented. The default value for the optional parameter is null
.
Remarks
This method overload lets you provide more eviction or expiration details than those that are available in time-based absolute expiration.
If an item that matches key
does not exist in the cache, value
and key
are used to insert as a new cache entry. If an item with a key that matches item
exists, the cache entry is updated or overwritten by using value
.
