Method Summary

Modifier and Type	Method and Description
com.google.common.util.concurrent.ListenableFuture<Urlfrontier.Empty>	blockQueueUntil(Urlfrontier.BlockQueueParams request) Block a queue from sending URLs; the argument is the number of seconds of UTC time since Unix epoch 1970-01-01T00:00:00Z.
protected URLFrontierGrpc.URLFrontierFutureStub	build(io.grpc.Channel channel, io.grpc.CallOptions callOptions)
com.google.common.util.concurrent.ListenableFuture<Urlfrontier.Integer>	deleteQueue(Urlfrontier.String request) Delete the queue based on the key in parameter, returns the number of URLs removed this way *
com.google.common.util.concurrent.ListenableFuture<Urlfrontier.Stats>	getStats(Urlfrontier.String request) Return stats for a specific queue or the whole crawl if the value if empty or null *
com.google.common.util.concurrent.ListenableFuture<Urlfrontier.StringList>	listQueues(Urlfrontier.Integer request) Return the names of up to N active queues a queue is active if it has URLs due for fetching; the default value of 0 sets no limit to the number of queue names to return *
com.google.common.util.concurrent.ListenableFuture<Urlfrontier.Empty>	setActive(Urlfrontier.Boolean request) De/activate the crawl.
com.google.common.util.concurrent.ListenableFuture<Urlfrontier.Empty>	setDelay(Urlfrontier.QueueDelayParams request) Set a delay from a given queue.

build

protected URLFrontierGrpc.URLFrontierFutureStub build(io.grpc.Channel channel,
                                                      io.grpc.CallOptions callOptions)

Specified by:

build in class io.grpc.stub.AbstractStub<URLFrontierGrpc.URLFrontierFutureStub>

listQueues

public com.google.common.util.concurrent.ListenableFuture<Urlfrontier.StringList> listQueues(Urlfrontier.Integer request)

 Return the names of up to N active queues
a queue is active if it has URLs due for fetching; the default value of 0 sets no limit to the number of queue names to return *
 

getStats

public com.google.common.util.concurrent.ListenableFuture<Urlfrontier.Stats> getStats(Urlfrontier.String request)

 Return stats for a specific queue or the whole crawl if the value if empty or null *
 

deleteQueue

public com.google.common.util.concurrent.ListenableFuture<Urlfrontier.Integer> deleteQueue(Urlfrontier.String request)

 Delete the queue based on the key in parameter, returns the number of URLs removed this way *
 

blockQueueUntil

public com.google.common.util.concurrent.ListenableFuture<Urlfrontier.Empty> blockQueueUntil(Urlfrontier.BlockQueueParams request)

 Block a queue from sending URLs; the argument is the number of seconds of UTC time since Unix epoch
1970-01-01T00:00:00Z. The default value of 0 will unblock the queue. The block will get removed once the time
indicated in argument is reached. This is useful for cases where a server returns a Retry-After for instance. 
 

setActive

public com.google.common.util.concurrent.ListenableFuture<Urlfrontier.Empty> setActive(Urlfrontier.Boolean request)

 De/activate the crawl. GetURLs will not return anything until SetActive is set to true. PutURLs will still take incoming data. *
 

setDelay

public com.google.common.util.concurrent.ListenableFuture<Urlfrontier.Empty> setDelay(Urlfrontier.QueueDelayParams request)

 Set a delay from a given queue.
No URLs will be obtained via GetURLs for this queue until the number of seconds specified has 
elapsed since the last time URLs were retrieved.
Usually informed by the delay setting of robots.txt.
