ByteBufferPool - Interface in com.hubject.aws.s3.io

ByteBufferPool.Companion - Class in com.hubject.aws.s3.io

C

close() - Method in class com.hubject.aws.s3.io.S3OutputStream

Fully flushes the stream and completes the upload.

com.hubject.aws.s3.io - package com.hubject.aws.s3.io

Companion - Static variable in interface com.hubject.aws.s3.io.ByteBufferPool

Companion - Static variable in class com.hubject.aws.s3.io.S3OutputStream

D

default() - Method in class com.hubject.aws.s3.io.ByteBufferPool.Companion

F

flush() - Method in class com.hubject.aws.s3.io.S3OutputStream

Flushes this ONLY if there is enough data in the buffer, see MIN_UPLOAD_PART_SIZE

free(buffer) - Method in interface com.hubject.aws.s3.io.ByteBufferPool

Returns this buffer to the pool. User code must not hold any references to the given buffer after this method returns.

free(buffer) - Method in class com.hubject.aws.s3.io.SimpleByteBufferPool

Returns this buffer to the pool. User code must not hold any references to the given buffer after this method returns.

G

getActualLocalCache() - Method in class com.hubject.aws.s3.io.S3OutputStream

The actual amount of local cache; this caps the requested maxLocalCache to what the ByteBuffers can hold (2GiB each).

getAllocateDirect() - Method in class com.hubject.aws.s3.io.SimpleByteBufferPool

Whether to allocate memory off-heap.

getAwsS3() - Method in class com.hubject.aws.s3.io.S3OutputStream

The client to upload with

getBucketName() - Method in exception com.hubject.aws.s3.io.S3ObjectAlreadyExistsException

getKey() - Method in exception com.hubject.aws.s3.io.S3ObjectAlreadyExistsException

getMaxLocalCache() - Method in class com.hubject.aws.s3.io.S3OutputStream

The maximum amount of memory to use as buffer,

getMaxSpareBuffers() - Method in class com.hubject.aws.s3.io.SimpleByteBufferPool

Maximum number of spare buffers

getTargetBucket() - Method in class com.hubject.aws.s3.io.S3OutputStream

getTargetS3Key() - Method in class com.hubject.aws.s3.io.S3OutputStream

getUseChecksums() - Method in class com.hubject.aws.s3.io.S3OutputStream

Whether to calculate MD5 checksums of the uploaded data.

M

MAX_SINGLE_FILE_UPLOAD_SIZE - Static variable in class com.hubject.aws.s3.io.S3OutputStream

The maximum size for a single file upload. This value is defined by the AWS S3 people.

MAX_UPLOAD_PART_SIZE - Static variable in class com.hubject.aws.s3.io.S3OutputStream

The maximum size of a single part in a multipart upload. This value is defined by the AWS S3 people.

Md5Kt - Class in com.hubject.aws.s3.io

MIN_UPLOAD_PART_SIZE - Static variable in class com.hubject.aws.s3.io.S3OutputStream

The minimum size for single parts of multipart uploads. This value is defined by the AWS S3 people.

P

pop(minSize) - Method in interface com.hubject.aws.s3.io.ByteBufferPool

Returns a buffer that has at least the given amount of bytes of available space. If no such buffer is currently free, one will be allocated.

pop(minSize) - Method in class com.hubject.aws.s3.io.SimpleByteBufferPool

Returns a buffer that has at least the given amount of bytes of available space. If no such buffer is currently free, one will be allocated.

S

S3ObjectAlreadyExistsException - Exception in com.hubject.aws.s3.io

S3ObjectAlreadyExistsException(bucketName, key) - Constructor for exception com.hubject.aws.s3.io.S3ObjectAlreadyExistsException

S3OutputStream - Class in com.hubject.aws.s3.io

Facilitates streaming to S3 in case the actual file size is not known upfront: uploading via the regular single-file upload will cache the contents in memory and cause an out-of-memory error, especially on AWS lambda. This may happen if you have to stream several GB to S3.

S3OutputStream(awsS3, targetBucket, targetS3Key, maxLocalCache, useChecksums, byteBufferPool) - Constructor for class com.hubject.aws.s3.io.S3OutputStream

Facilitates streaming to S3 in case the actual file size is not known upfront: uploading via the regular single-file upload will cache the contents in memory and cause an out-of-memory error, especially on AWS lambda. This may happen if you have to stream several GB to S3.

S3OutputStream.Companion - Class in com.hubject.aws.s3.io

SimpleByteBufferPool - Class in com.hubject.aws.s3.io

A pool for byte buffers, similar to connection pools. Avoids frequent re-allocation.

SimpleByteBufferPool(allocateDirect, maxSpareBuffers) - Constructor for class com.hubject.aws.s3.io.SimpleByteBufferPool

A pool for byte buffers, similar to connection pools. Avoids frequent re-allocation.

SimpleByteBufferPool(allocateDirect) - Constructor for class com.hubject.aws.s3.io.SimpleByteBufferPool

A pool for byte buffers, similar to connection pools. Avoids frequent re-allocation.

SimpleByteBufferPool() - Constructor for class com.hubject.aws.s3.io.SimpleByteBufferPool

A pool for byte buffers, similar to connection pools. Avoids frequent re-allocation.
