Method Detail

preGetOp

public void preGetOp(ObserverContext<RegionCoprocessorEnvironment> e,
                     Get get,
                     java.util.List<Cell> results)

Description copied from interface: RegionObserver

Called before the client performs a Get

Call CoprocessorEnvironment#bypass to skip default actions

Call CoprocessorEnvironment#complete to skip any subsequent chained coprocessors

Specified by:

preGetOp in interface RegionObserver

Overrides:

preGetOp in class BaseRegionObserver

Parameters:

e - the environment provided by the region server

get - the Get request

results - The result to return to the client if default processing is bypassed. Can be modified. Will not be used if default processing is not bypassed.

Throws:

java.io.IOException - if an error occurred on the coprocessor
