###### Assembly: Apache.Ignite.Linq.dll

##### Syntax

    public static class CacheClientLinqExtensions : object

### Methods

#### AsCacheQueryable<TKey, TValue>(ICacheClient<TKey, TValue>)

Gets an instance over this cache.

Resulting query will be translated to cache SQL query and executed over the cache instance via either Query(SqlFieldsQuery).

Result of this method (and subsequent query) can be cast to ICacheQueryable for introspection, or converted with ToCacheQueryable<T>(IQueryable<T>) extension method.

##### Declaration

    public static IQueryable<ICacheEntry<TKey, TValue>> AsCacheQueryable<TKey, TValue>(this ICacheClient<TKey, TValue> cache)

##### Parameters

Type | Name | Description
--- | --- | ---
ICacheClient<TKey, TValue> | cache | The cache.

##### Returns

Type | Description
--- | ---
IQueryable<ICacheEntry<TKey, TValue>> | instance over this cache.

##### Type Parameters

Name | Description
--- | ---
TKey | The type of the key.
TValue | The type of the value.

#### AsCacheQueryable<TKey, TValue>(ICacheClient<TKey, TValue>, QueryOptions)

Gets an instance over this cache.

Resulting query will be translated to cache SQL query and executed over the cache instance via either Query(SqlFieldsQuery).

Result of this method (and subsequent query) can be cast to ICacheQueryable for introspection.

##### Declaration

    public static IQueryable<ICacheEntry<TKey, TValue>> AsCacheQueryable<TKey, TValue>(this ICacheClient<TKey, TValue> cache, QueryOptions queryOptions)

##### Parameters

Type | Name | Description
--- | --- | ---
ICacheClient<TKey, TValue> | cache | The cache.
QueryOptions | queryOptions | The query options.

##### Returns

Type | Description
--- | ---
IQueryable<ICacheEntry<TKey, TValue>> | instance over this cache.

##### Type Parameters

Name | Description
--- | ---
TKey | The type of the key.
TValue | The type of the value.

#### AsCacheQueryable<TKey, TValue>(ICacheClient<TKey, TValue>, Boolean)

Gets an instance over this cache.

Resulting query will be translated to cache SQL query and executed over the cache instance via either Query(SqlFieldsQuery).

Result of this method (and subsequent query) can be cast to ICacheQueryable for introspection.

##### Declaration

    public static IQueryable<ICacheEntry<TKey, TValue>> AsCacheQueryable<TKey, TValue>(this ICacheClient<TKey, TValue> cache, bool local)

##### Parameters

Type | Name | Description
--- | --- | ---
ICacheClient<TKey, TValue> | cache | The cache.
System.Boolean | local | Local flag. When set query will be executed only on local node, so only local entries will be returned as query result.

##### Returns

Type | Description
--- | ---
IQueryable<ICacheEntry<TKey, TValue>> | instance over this cache.

##### Type Parameters

Name | Description
--- | ---
TKey | The type of the key.
TValue | The type of the value.

#### AsCacheQueryable<TKey, TValue>(ICacheClient<TKey, TValue>, Boolean, String)

Gets an instance over this cache.

Resulting query will be translated to cache SQL query and executed over the cache instance via either Query(SqlFieldsQuery).

Result of this method (and subsequent query) can be cast to ICacheQueryable for introspection.

##### Declaration

    public static IQueryable<ICacheEntry<TKey, TValue>> AsCacheQueryable<TKey, TValue>(this ICacheClient<TKey, TValue> cache, bool local, string tableName)

##### Parameters

Type | Name | Description
--- | --- | ---
ICacheClient<TKey, TValue> | cache | The cache.
System.Boolean | local | Local flag. When set query will be executed only on local node, so only local entries will be returned as query result.
System.String | tableName | Name of the table. Table name is equal to short class name of a cache value. When a cache has only one type of values, or only one QueryEntity defined, table name will be inferred and can be omitted.

##### Returns

Type | Description
--- | ---
IQueryable<ICacheEntry<TKey, TValue>> | instance over this cache.

##### Type Parameters

Name | Description
--- | ---
TKey | The type of the key.
