protected BaseWriteChannel(ServiceOptionsT options, EntityT entity, String uploadId)

Parameters

Name	Description
options	`ServiceOptionsT`
entity	`EntityT`
uploadId	`String`

Methods

capture()

public RestorableState<WriteChannel> capture()

Captures the write channel state so that it can be saved and restored afterwards. The original WriteChannel and the restored one should not both be used. Closing one channel causes the other channel to close; subsequent writes will fail.

Returns

Type	Description
RestorableState<WriteChannel>

close()

public final void close()

Exceptions

Type	Description
IOException

flushBuffer(int length, boolean last)

protected abstract void flushBuffer(int length, boolean last)

Writes length bytes of #getBuffer() to the #getUploadId() URL.

Parameters

Name	Description
length	`int` the number of bytes to write from #getBuffer()
last	`boolean` if `true` the resumable session is closed

getBuffer()

protected byte[] getBuffer()

Returns

Type	Description
byte[]

restore(BaseWriteChannel.BaseState state)

protected void restore(BaseWriteChannel.BaseState state)

Parameter

Name	Description
state	`BaseState`

setChunkSize(int chunkSize)

public final void setChunkSize(int chunkSize)

Sets the minimum size that will be written by a single RPC. Written data will be buffered and only flushed upon reaching this size or closing the channel.

Parameter

Name	Description
chunkSize	`int`

stateBuilder()

protected abstract BaseWriteChannel.BaseState.Builder<ServiceOptionsT,EntityT> stateBuilder()

Creates a BaseState.Builder for the current write channel.

Returns
