Enum ConsistentReadControl

java.lang.Object
java.lang.Enum<ConsistentReadControl>
com.azure.storage.blob.models.ConsistentReadControl
All Implemented Interfaces:
Serializable, Comparable<ConsistentReadControl>, java.lang.constant.Constable

public enum ConsistentReadControl extends Enum<ConsistentReadControl>
Defines values to indicate what strategy the SDK should use when reading from a blob to ensure the view of the data is consistent and not changed during the read. NONE ETAG VERSION_ID
  • Enum Constant Details

    • NONE

      public static final ConsistentReadControl NONE
      No consistent read control. The client will honor user provided MatchConditions.getIfMatch() and BlobClientBase.getVersionId().
    • ETAG

      public static final ConsistentReadControl ETAG
      Default value. Consistent read control based on eTag. If MatchConditions.getIfMatch() is set, the client will honor this value. Otherwise, MatchConditions.getIfMatch() is set to the latest eTag. Note: Modification of the base blob will result in an IOException or a BlobStorageException if eTag is the only form of consistent read control being employed.
    • VERSION_ID

      public static final ConsistentReadControl VERSION_ID
      Consistent control based on versionId. Note: Versioning must be supported by the account to use this value. If BlobClientBase.getVersionId() is set, the client will honor this value. Otherwise, BlobClientBase.getVersionId() is set to the latest versionId. Note: Modification of the base blob will not result in an Exception and allow you to continue reading the entirety of the appropriate version of the blob determined at the time of opening the InputStream but it may no longer be the latest data.

    • values

      public static ConsistentReadControl[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared
    • valueOf

      public static ConsistentReadControl valueOf(String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null
