Class Dispatcher

java.lang.Object

okhttp3.Dispatcher

public final class Dispatcher
extends Object

Policy on when async requests are executed.

Each dispatcher uses an ExecutorService to run calls internally. If you supply your own executor, it should be able to run the configured maximum number of calls concurrently.

Method Detail

executorService

public ExecutorService executorService()

setMaxRequests

public void setMaxRequests(int maxRequests)

Set the maximum number of requests to execute concurrently. Above this requests queue in memory, waiting for the running calls to complete.

If more than maxRequests requests are in flight when this is invoked, those requests will remain in flight.

getMaxRequests

public int getMaxRequests()

setMaxRequestsPerHost

public void setMaxRequestsPerHost(int maxRequestsPerHost)

Set the maximum number of requests for each host to execute concurrently. This limits requests by the URL's host name. Note that concurrent requests to a single IP address may still exceed this limit: multiple hostnames may share an IP address or be routed through the same HTTP proxy.

If more than maxRequestsPerHost requests are in flight when this is invoked, those requests will remain in flight.

WebSocket connections to hosts do not count against this limit.

getMaxRequestsPerHost

public int getMaxRequestsPerHost()

setIdleCallback

public void setIdleCallback(@Nullable
                            Runnable idleCallback)

Set a callback to be invoked each time the dispatcher becomes idle (when the number of running calls returns to zero).

Note: The time at which a call is considered idle is different depending on whether it was run asynchronously or synchronously. Asynchronous calls become idle after the onResponse or onFailure callback has returned. Synchronous calls become idle once execute() returns. This means that if you are doing synchronous calls the network layer will not truly be idle until every returned Response has been closed.

cancelAll

public void cancelAll()

Cancel all calls currently enqueued or executing. Includes calls executed both synchronously and asynchronously.

queuedCalls

public List<Call> queuedCalls()

Returns a snapshot of the calls currently awaiting execution.

runningCalls

public List<Call> runningCalls()

Returns a snapshot of the calls currently being executed.

queuedCallsCount

public int queuedCallsCount()

runningCallsCount

public int runningCallsCount()
