Constructors
| FileURL(string, Pipeline) | Creates an instance of FileURL. |
Inherited Properties
| url | URL string value. |
Methods

Aborts a pending Copy File operation, and leaves a destination file with zero length and full metadata. See https://docs.microsoft.com/en-us/rest/api/storageservices/abort-copy-file |
| clear |
Clears the specified range and releases the space used in storage for that range. |
| create(Aborter, number, IFile |
Creates a new file or replaces a file. Note it only initializes the file with no content. See https://docs.microsoft.com/en-us/rest/api/storageservices/create-file |
| delete(Aborter) | Removes the file from the storage account. When a file is successfully deleted, it is immediately removed from the storage account's index and is no longer accessible to clients. The file's data is later removed from the service during garbage collection. Delete File will fail with status code 409 (Conflict) and error code SharingViolation if the file is open on an SMB client. Delete File is not supported on a share snapshot, which is a read-only copy of a share. An attempt to perform this operation on a share snapshot will fail with 400 (InvalidQueryParameterValue) See https://docs.microsoft.com/en-us/rest/api/storageservices/delete-file2 |

Constructor Details
FileURL(string, Pipeline)
Creates an instance of FileURL.
new FileURL(url: string, pipeline: Pipeline)Parameters
- url
-
string
A URL string pointing to Azure Storage file, such as "https://myaccount.file.core.windows.net/myshare/mydirectory/file". You can append a SAS if using AnonymousCredential, such as "https://myaccount.file.core.windows.net/myshare/mydirectory/file?sasString". This method accepts an encoded URL or non-encoded URL pointing to a file. Encoded URL string will NOT be escaped twice, only special characters in URL path will be escaped. However, if a file or directory name includes %, file or directory name must be encoded in the URL. Such as a file named "myfile%", the URL should be "https://myaccount.file.core.windows.net/myshare/mydirectory/myfile%25".
