Method Detail

clear

public void clear()

Clears the map and unregisters all SolrInfoMBeans in the map from MBeanServer

Specified by:

clear in interface Map<String,SolrInfoMBean>

Overrides:

clear in class ConcurrentHashMap<String,SolrInfoMBean>

put

public SolrInfoMBean put(String key,
                SolrInfoMBean infoBean)

Adds the SolrInfoMBean to the map and registers the given SolrInfoMBean instance with the MBeanServer defined for this core. If a SolrInfoMBean is already registered with the MBeanServer then it is unregistered and then re-registered.

put in class ConcurrentHashMap<String,SolrInfoMBean>

Parameters:

key - the JMX type name for this SolrInfoMBean

infoBean - the SolrInfoMBean instance to be registered

remove

public SolrInfoMBean remove(Object key)

Removes the SolrInfoMBean object at the given key and unregisters it from MBeanServer

Specified by:

remove in interface Map<String,SolrInfoMBean>

Overrides:

remove in class ConcurrentHashMap<String,SolrInfoMBean>

Parameters:

key - the JMX type name for this SolrInfoMBean
