gemfire::CqAttributesMutator Class Reference

Inherits gemfire::SharedBase.

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.

Public Member Functions
virtual void	addCqListener (const CqListenerPtr &aListener)=0
	Adds a CQ listener to the end of the list of CQ listeners on this CqQuery.
void	preserveSB () const
	Atomically increment reference count.

	Returns: the reference count
void	releaseSB () const
	Atomically decrement reference count, the SharedBase object is automatically deleted when its reference count goes to zero.
virtual void	removeCqListener (const CqListenerPtr &aListener)=0
	Removes given CQ listener from the list of CQ listeners on this CqQuery.
virtual void	setCqListeners (VectorOfCqListener &newListeners)=0
	Adds the given set CqListner on this CQ.

Member Function Documentation

virtual void gemfire::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 gemfire::SharedBase::preserveSB

(

)

const [inherited]

Atomically increment reference count.

int32_t gemfire::SharedBase::refCount

(

)

[inline, inherited]

Returns:

the reference count

void gemfire::SharedBase::releaseSB

(

)

const [inherited]

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

virtual void gemfire::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 gemfire::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
