Methods

GetPath(IImplementationStore, ImplementationBase)

Determines the local path of an implementation.

public static string GetPath(this IImplementationStore store, ImplementationBase implementation)

Parameters

store IImplementationStore

The store containing the implementation.

implementation ImplementationBase

The implementation to be located.

Returns

string

A fully qualified path to the directory containing the implementation.

Exceptions

ImplementationNotFoundException

The implementation is not cached yet.

UnauthorizedAccessException

Read access to the store is not permitted.

IsImplementation(string, out string?)

Determines whether a path looks like it is inside a store implementation known by ManifestFormat.

public static bool IsImplementation(string path, out string? implementationPath)

Parameters

path string

A path to a directory that may or may not be inside a store implementation.

implementationPath string

The top-level of the detected store implementation directory if any; null otherwise.

Returns

bool

Remarks

Performs no file system access. Only looks at the path string itself.

Verify(string, ManifestDigest, ITaskHandler)

Checks whether an implementation directory matches the expected digest. Throws DigestMismatchException if it does not match.

public static void Verify(string path, ManifestDigest manifestDigest, ITaskHandler handler)

Parameters

path string

The path of the directory ot check.

manifestDigest ManifestDigest

The expected digest.

handler ITaskHandler
