Method Details

setProgressVisitor

public void setProgressVisitor(org.h2gis.api.ProgressVisitor progressVisitor)

hasAvaibleQueueSlot

public boolean hasAvaibleQueueSlot()

Returns:

True if poolSize is inferior of maximum pool size

getRemainingTasks

public int getRemainingTasks()

Returns:

Remaining threads Running and queued

executeBlocking

public void executeBlocking(Runnable command)

Wait for free queue slot if poolSize is superior or equal of maximum pool size then executes the given task sometime in the future. The task may execute in a new thread or in an existing pooled thread. If the task cannot be submitted for execution, either because this executor has been shutdown or because its capacity has been reached, the task is handled by the current RejectedExecutionHandler.

Parameters:

command -

submitBlocking

public <T> Future<T> submitBlocking(Callable<T> task)

Wait for free queue slot if poolSize is superior or equal of maximum pool size then executes the given task sometime in the future. The task may execute in a new thread or in an existing pooled thread. If the task cannot be submitted for execution, either because this executor has been shutdown or because its capacity has been reached, the task is handled by the current RejectedExecutionHandler.
