Method Details

isBlocked

com.google.common.util.concurrent.ListenableFuture<Void> isBlocked()

This method may be called by multiple independent client concurrently. Implementations must ensure the cancellation of a future by one of the clients doesn't cancel futures obtained by other clients.

pollPage

io.airlift.slice.Slice pollPage()

addTask

void addTask(TaskId taskId)

addPages

void addPages(TaskId taskId,
 List<io.airlift.slice.Slice> pages)

taskFinished

void taskFinished(TaskId taskId)

taskFailed

void taskFailed(TaskId taskId,
 Throwable t)

noMoreTasks

void noMoreTasks()

isFinished

boolean isFinished()

isFailed

boolean isFailed()

getRemainingCapacityInBytes

long getRemainingCapacityInBytes()

getRetainedSizeInBytes

long getRetainedSizeInBytes()

getMaxRetainedSizeInBytes

long getMaxRetainedSizeInBytes()

getBufferedPageCount

int getBufferedPageCount()

getSpilledBytes

long getSpilledBytes()

getSpilledPageCount

int getSpilledPageCount()
