Initializes a new instance of the ServiceCache class.

Declaration
public ServiceCache(IGraphLogger logger, IGraphClient client, ISerializer serializer, string baseUri)
Parameters
Type Name Description
IGraphLogger logger

Logger instance.
IGraphClient client

The client.
ISerializer serializer

The serializer.
String baseUri

The base URI.

Methods

GetDataAsync<T>(IEnumerable<IGraphProperty>, String, CancellationToken)

Gets the serialized string of the data at the specified resource path asynchronously. Fetching data only happens in HA/DR scenarios, so could take longer.

Declaration
public Task<string> GetDataAsync<T>(IEnumerable<IGraphProperty> properties, string resourcePath, CancellationToken cancellationToken = default(CancellationToken))

    where T : Entity
Parameters
Type Name Description
IEnumerable<IGraphProperty> properties

The properties.
String resourcePath

The resource path.
CancellationToken cancellationToken

The cancellation token.
Returns
Type Description
Task<String>

The recovered serialized data at the specified resource path.
Type Parameters
Name Description
T

The type of Entity to fetch.

GetDataCollectionAsync<T>(IEnumerable<IGraphProperty>, String, CancellationToken)

Gets the resource paths for the children of the collection with the specified resource path asynchronously. Fetching data only happens in HA/DR scenarios, so could take longer.

Declaration
public Task<IEnumerable<string>> GetDataCollectionAsync<T>(IEnumerable<IGraphProperty> properties, string resourcePath, CancellationToken cancellationToken = default(CancellationToken))

    where T : Entity
Parameters
Type Name Description
IEnumerable<IGraphProperty> properties

The properties.
String resourcePath

The resource path.
CancellationToken cancellationToken

The cancellation token.
Returns
Type Description
Task<IEnumerable<String>>

The recovered collection or child resource paths.
Type Parameters
Name Description
T

The type of Entity contained in the collection.

SetData(ChangeType, IResource, IEnumerable<IGraphProperty>, String, Lazy<String>)

Sets the data under the specified resource path. These should be short running operations, as they block notification callbacks.

Declaration
public void SetData(ChangeType change, IResource resource, IEnumerable<IGraphProperty> properties, string resourcePath, Lazy<string> serializedData)
Parameters
Type Name Description
ChangeType change

The type of change occuring.
IResource resource

The resource being serialized.
IEnumerable<IGraphProperty> properties

The properties.
String resourcePath

The resource path.
Lazy<String> serializedData

The serialized data lazy string. For performance reasons the string is only serialized when requested.
