public sealed class ObjectConditions : IMessage<ObjectConditions>, IEquatable<ObjectConditions>, IDeepCloneable<ObjectConditions>, IBufferMessage, IMessageReference documentation and code samples for the Storage Transfer v1 API class ObjectConditions.
Conditions that determine which objects are transferred. Applies only to Cloud Data Sources such as S3, Azure, and Cloud Storage.
The "last modification time" refers to the time of the
last change to the object's content or metadata — specifically, this is
the updated property of Cloud Storage objects, the LastModified field
of S3 objects, and the Last-Modified header of Azure blobs.
Transfers with a [PosixFilesystem][google.storagetransfer.v1.PosixFilesystem]
source or destination don't support ObjectConditions.

Properties
ExcludePrefixes
public RepeatedField<string> ExcludePrefixes { get; }If you specify exclude_prefixes, Storage Transfer Service uses the items
in the exclude_prefixes array to determine which objects to exclude from
a transfer. Objects must not start with one of the matching
exclude_prefixes for inclusion in a transfer.
The following are requirements of exclude_prefixes:
Each exclude-prefix can contain any sequence of Unicode characters, to a max length of 1024 bytes when UTF8-encoded, and must not contain Carriage Return or Line Feed characters. Wildcard matching and regular expression matching are not supported.
Each exclude-prefix must omit the leading slash. For example, to exclude the object
s3://my-aws-bucket/logs/y=2015/requests.gz, specify the exclude-prefix aslogs/y=2015/requests.gz.None of the exclude-prefix values can be empty, if specified.
Each exclude-prefix must exclude a distinct portion of the object namespace. No exclude-prefix may be a prefix of another exclude-prefix.
If [include_prefixes][google.storagetransfer.v1.ObjectConditions.include_prefixes] is specified, then each exclude-prefix must start with the value of a path explicitly included by
include_prefixes.
The max size of exclude_prefixes is 1000.

transfer. Objects must start with one of the matching include_prefixes
for inclusion in the transfer. If

LastModifiedBefore
public Timestamp LastModifiedBefore { get; set; }If specified, only objects with a "last modification time" before this timestamp and objects that don't have a "last modification time" are transferred.

LastModifiedSince
public Timestamp LastModifiedSince { get; set; }If specified, only objects with a "last modification time" on or after this timestamp and objects that don't have a "last modification time" are transferred.
The last_modified_since and last_modified_before fields can be used
together for chunked data processing. For example, consider a script that
processes each day's worth of data at a time. For that you'd set each
of the fields as follows:
last_modified_sinceto the start of the daylast_modified_beforeto the end of the day

MaxTimeElapsedSinceLastModification
public Duration MaxTimeElapsedSinceLastModification { get; set; }Ensures that objects are not transferred if a specific maximum time
has elapsed since the "last modification time".
When a [TransferOperation][google.storagetransfer.v1.TransferOperation]
begins, objects with a "last modification time" are transferred only if the
elapsed time between the
[start_time][google.storagetransfer.v1.TransferOperation.start_time] of the
TransferOperationand the "last modification time" of the object
is less than the value of max_time_elapsed_since_last_modification`.
Objects that do not have a "last modification time" are also transferred.

MinTimeElapsedSinceLastModification
public Duration MinTimeElapsedSinceLastModification { get; set; }Ensures that objects are not transferred until a specific minimum time
has elapsed after the "last modification time". When a
[TransferOperation][google.storagetransfer.v1.TransferOperation] begins,
objects with a "last modification time" are transferred only if the elapsed
time between the
[start_time][google.storagetransfer.v1.TransferOperation.start_time] of the
TransferOperation and the "last modification time" of the object is equal
to or greater than the value of min_time_elapsed_since_last_modification`.
Objects that do not have a "last modification time" are also transferred.
