Detailed Description

This interface is used to modify the listeners that are associated with a CQ.

Each CqQuery has an CqAttributesMutator interface which supports modification of certain CQ attributes after the CQ has been created.

Member Function Documentation

virtual void apache::geode::client::CqAttributesMutator::addCqListener ( const CqListenerPtr &  aListener )

pure virtual

Adds a CQ listener to the end of the list of CQ listeners on this CqQuery.

Parameters

aListener

the user defined CQ listener to add to the CqQuery.

Exceptions

IllegalArgumentException

if aListener is NULLPTR

void apache::geode::client::SharedBase::preserveSB ( ) const

inherited

Atomically increment reference count.

int32_t apache::geode::client::SharedBase::refCount ( )

inlineinherited

Returns

the reference count

void apache::geode::client::SharedBase::releaseSB ( ) const

inherited

Atomically decrement reference count, the SharedBase object is automatically deleted when its reference count goes to zero.

virtual void apache::geode::client::CqAttributesMutator::removeCqListener ( const CqListenerPtr &  aListener )

pure virtual

Removes given CQ listener from the list of CQ listeners on this CqQuery.

Does nothing if the specified listener has not been added. If the specified listener has been added then will be called on it; otherwise does nothing.

Parameters

aListener

the CQ listener to remove from the CqQuery.

Exceptions

IllegalArgumentException

if aListener is NULLPTR

virtual void apache::geode::client::CqAttributesMutator::setCqListeners ( VectorOfCqListener &  newListeners )

pure virtual

Adds the given set CqListner on this CQ.

If the CQ already has CqListeners, this removes those old CQs and initializes with the newListeners.

Parameters

newListeners

a possibly empty array of listeners to add to this CqQuery.

Exceptions

IllegalArgumentException

if the newListeners array has a NULLPTR element
