Method Summary

Modifier and Type	Method and Description
void	close() Implementations should always call SolrMetricProducer.super.close() to ensure that metrics with the same life-cycle as this component are properly unregistered.
SolrInfoBean.Category	getCategory() Category of this component
int	getConnectionTimeout()
org.apache.http.impl.conn.PoolingHttpClientConnectionManager	getDefaultConnectionManager()
org.apache.http.client.HttpClient	getDefaultHttpClient()
String	getDescription() Simple one or two line description
Set<String>	getMetricNames() Modifiable set of metric names that this component reports (default is null, which means none).
String	getName() Simple common usage name, e.g.
ExecutorService	getRecoveryExecutor()
org.apache.http.impl.conn.PoolingHttpClientConnectionManager	getRecoveryOnlyConnectionManager()
org.apache.http.client.HttpClient	getRecoveryOnlyHttpClient()
int	getSocketTimeout()
SolrMetricsContext	getSolrMetricsContext() Implementing classes should override this method to provide the context obtained in SolrMetricProducer.initializeMetrics(SolrMetricsContext, String) to ensure proper cleanup of metrics at the end of the life-cycle of this component.
ExecutorService	getUpdateExecutor() This method returns an executor that is meant for non search related tasks.
Http2SolrClient	getUpdateOnlyHttpClient()
void	initializeMetrics(SolrMetricsContext parentContext, String scope) Initialize metrics specific to this producer.

Method Detail

getName

public String getName()

Description copied from interface: SolrInfoBean

Simple common usage name, e.g. BasicQueryHandler, or fully qualified class name.

Specified by:

getName in interface SolrInfoBean

initializeMetrics

public void initializeMetrics(SolrMetricsContext parentContext,
                              String scope)

Description copied from interface: SolrMetricProducer

Initialize metrics specific to this producer.

Specified by:

initializeMetrics in interface SolrMetricProducer

Parameters:

parentContext - parent metrics context. If this component has the same life-cycle as the parent it can simply use the parent context, otherwise it should obtain a child context using SolrMetricsContext.getChildContext(Object) passing this as the child.

scope - component scope

getDescription

public String getDescription()

Description copied from interface: SolrInfoBean

Simple one or two line description

Specified by:

getDescription in interface SolrInfoBean

getCategory

public SolrInfoBean.Category getCategory()

Description copied from interface: SolrInfoBean

Category of this component

Specified by:

getCategory in interface SolrInfoBean

getMetricNames

public Set<String> getMetricNames()

Description copied from interface: SolrInfoBean

Modifiable set of metric names that this component reports (default is null, which means none). If not null then this set is used by SolrInfoBean.registerMetricName(String) to capture what metrics names are reported from this component.

NOTE: this set has to allow iteration under modifications.

Specified by:

getMetricNames in interface SolrInfoBean

getSolrMetricsContext

public SolrMetricsContext getSolrMetricsContext()

Description copied from interface: SolrMetricProducer

Implementing classes should override this method to provide the context obtained in SolrMetricProducer.initializeMetrics(SolrMetricsContext, String) to ensure proper cleanup of metrics at the end of the life-cycle of this component.

Specified by:

getSolrMetricsContext in interface SolrMetricProducer

getDefaultHttpClient

public org.apache.http.client.HttpClient getDefaultHttpClient()

getUpdateOnlyHttpClient

public Http2SolrClient getUpdateOnlyHttpClient()

getRecoveryOnlyHttpClient

public org.apache.http.client.HttpClient getRecoveryOnlyHttpClient()

getUpdateExecutor

public ExecutorService getUpdateExecutor()

This method returns an executor that is meant for non search related tasks.

Returns:

an executor for update side related activities.

getDefaultConnectionManager

public org.apache.http.impl.conn.PoolingHttpClientConnectionManager getDefaultConnectionManager()

getRecoveryOnlyConnectionManager

public org.apache.http.impl.conn.PoolingHttpClientConnectionManager getRecoveryOnlyConnectionManager()

getRecoveryExecutor

public ExecutorService getRecoveryExecutor()

Returns:

executor for recovery operations

close

public void close()

Description copied from interface: SolrMetricProducer

Implementations should always call SolrMetricProducer.super.close() to ensure that metrics with the same life-cycle as this component are properly unregistered. This prevents obscure memory leaks. from: https://docs.oracle.com/javase/8/docs/api/java/lang/AutoCloseable.html While this interface method is declared to throw Exception, implementers are strongly encouraged to declare concrete implementations of the close method to throw more specific exceptions, or to throw no exception at all if the close operation cannot fail.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface SolrMetricProducer

getSocketTimeout

public int getSocketTimeout()

getConnectionTimeout

public int getConnectionTimeout()

setSecurityBuilder

public void setSecurityBuilder(HttpClientBuilderPlugin builder)
