Method Summary

Modifier and Type	Method	Description
S3TransferManager	build()	Builds an instance of S3TransferManager based on the settings supplied to this builder
S3TransferManager.Builder	executor(Executor executor)	Specifies the executor that S3TransferManager will use to execute background tasks before handing them off to the underlying S3 async client, such as visiting file tree in a S3TransferManager.uploadDirectory(UploadDirectoryRequest) operation.
S3TransferManager.Builder	s3Client(S3AsyncClient s3AsyncClient)	Specifies the low level S3AsyncClient that will be used to send requests to S3.
S3TransferManager.Builder	uploadDirectoryFollowSymbolicLinks(Boolean uploadDirectoryFollowSymbolicLinks)	Specifies whether to follow symbolic links when traversing the file tree in S3TransferManager.uploadDirectory(software.amazon.awssdk.transfer.s3.model.UploadDirectoryRequest) operation
S3TransferManager.Builder	uploadDirectoryMaxDepth(Integer uploadDirectoryMaxDepth)	Specifies the maximum number of levels of directories to visit in S3TransferManager.uploadDirectory(software.amazon.awssdk.transfer.s3.model.UploadDirectoryRequest) operation.

Method Details

s3Client

S3TransferManager.Builder s3Client(S3AsyncClient s3AsyncClient)

Specifies the low level S3AsyncClient that will be used to send requests to S3. The SDK will create a default S3AsyncClient if not provided.

It's highly recommended to use S3AsyncClient.crtBuilder() to create an S3AsyncClient instance to benefit from multipart upload/download feature and maximum throughput.

Note: the provided S3AsyncClient will not be closed when the transfer manager is closed; it must be closed by the caller when it is ready to be disposed.

Parameters:

s3AsyncClient - the S3 async client

Returns:

Returns a reference to this object so that method calls can be chained together.

executor

S3TransferManager.Builder executor(Executor executor)

Specifies the executor that S3TransferManager will use to execute background tasks before handing them off to the underlying S3 async client, such as visiting file tree in a S3TransferManager.uploadDirectory(UploadDirectoryRequest) operation.

The SDK will create an executor if not provided.

This executor must be shut down by the user when it is ready to be disposed. The SDK will not close the executor when the s3 transfer manager is closed.

Parameters:

executor - the executor to use

Returns:

this builder for method chaining.

uploadDirectoryFollowSymbolicLinks

S3TransferManager.Builder uploadDirectoryFollowSymbolicLinks(Boolean uploadDirectoryFollowSymbolicLinks)

Specifies whether to follow symbolic links when traversing the file tree in S3TransferManager.uploadDirectory(software.amazon.awssdk.transfer.s3.model.UploadDirectoryRequest) operation

Default to false

Parameters:

uploadDirectoryFollowSymbolicLinks - whether to follow symbolic links

Returns:

This builder for method chaining.

uploadDirectoryMaxDepth

S3TransferManager.Builder uploadDirectoryMaxDepth(Integer uploadDirectoryMaxDepth)

Specifies the maximum number of levels of directories to visit in S3TransferManager.uploadDirectory(software.amazon.awssdk.transfer.s3.model.UploadDirectoryRequest) operation. Must be positive. 1 means only the files directly within the provided source directory are visited.

Default to Integer.MAX_VALUE

Parameters:

uploadDirectoryMaxDepth - the maximum number of directory levels to visit

Returns:

This builder for method chaining.

build

S3TransferManager build()

Builds an instance of S3TransferManager based on the settings supplied to this builder

Returns:

an instance of S3TransferManager
