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()

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
