从类复制的说明: CoprocessorHost

Called when a new Coprocessor class is loaded

指定者:

createEnvironment 在类中 CoprocessorHost<RegionServerCoprocessor,RegionServerCoprocessorEnvironment>

checkAndGetInstance

public RegionServerCoprocessor checkAndGetInstance(Class<?> implClass)
                                            throws InstantiationException,
                                                   IllegalAccessException

从类复制的说明: CoprocessorHost

Called when a new Coprocessor class needs to be loaded. Checks if type of the given class is what the corresponding host implementation expects. If it is of correct type, returns an instance of the coprocessor to be loaded. If not, returns null. If an exception occurs when trying to create instance of a coprocessor, it's passed up and eventually results into server aborting.

指定者:

checkAndGetInstance 在类中 CoprocessorHost<RegionServerCoprocessor,RegionServerCoprocessorEnvironment>

抛出:

InstantiationException

IllegalAccessException
