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[]`

getChunkSize()

protected int getChunkSize()

Returns
Type	Description
`int`

getDefaultChunkSize()

protected int getDefaultChunkSize()

Returns
Type	Description
`int`

getEntity()

protected EntityT getEntity()

Returns
Type	Description
`EntityT`

getLimit()

protected int getLimit()

Returns
Type	Description
`int`

getMinChunkSize()

protected int getMinChunkSize()

Returns
Type	Description
`int`

getOptions()

protected ServiceOptionsT getOptions()

Returns
Type	Description
`ServiceOptionsT`

getPosition()

protected long getPosition()

Returns
Type	Description
`long`

getUploadId()

protected String getUploadId()

Returns
Type	Description
`String`

isOpen()

public boolean isOpen()

Returns
Type	Description
`boolean`

restore(BaseWriteChannel.BaseState state)

protected void restore(BaseWriteChannel.BaseState state)

Restores the state of the current write channel given a BaseState object.

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
Type	Description
`Builder<ServiceOptionsT,EntityT>`

write(ByteBuffer byteBuffer)

public final int write(ByteBuffer byteBuffer)

Parameter
Name	Description
`byteBuffer`	`ByteBuffer`

Returns
Type	Description
`int`
