Package com.azure.storage.blob.nio

Class AzureBasicFileAttributes

java.lang.Object
com.azure.storage.blob.nio.AzureBasicFileAttributes
All Implemented Interfaces:
BasicFileAttributes
public final class AzureBasicFileAttributes extends Object implements BasicFileAttributes
Provides support for basic file attributes.

The properties available on this type are a strict subset of AzureBlobFileAttributes, and the two types have the same network behavior. Therefore, while this type is offered for compliance with the NIO spec, AzureBlobFileAttributes is generally preferred.

Some attributes are not supported. Refer to the javadocs on each method for more information.

If the target file is a virtual directory, most attributes will be set to null.

  • Method Details

    • lastModifiedTime

      public FileTime lastModifiedTime()
      Returns the time of last modification or null if this is a virtual directory.
      Specified by:
      lastModifiedTime in interface BasicFileAttributes
      Returns:
      the time of last modification or null if this is a virtual directory

    • lastAccessTime

      public FileTime lastAccessTime()
      Returns the time of last modification or null if this is a virtual directory

      Last access time is not supported by the blob service. In this case, it is typical for implementations to return the lastModifiedTime().

      lastAccessTime in interface BasicFileAttributes
      Returns:
      the time of last modification or null if this is a virtual directory

    • creationTime

      public FileTime creationTime()
      Returns the creation time. The creation time is the time that the file was created. Returns null if this is a virtual directory.
      Specified by:
      creationTime in interface BasicFileAttributes
      Returns:
      The creation time or null if this is a virtual directory

    • isDirectory

      public boolean isDirectory()
