onRegion()

static Execution apache::geode::client::FunctionService::onRegion ( const std::shared_ptr< Region > &  region )

static

Returns a Execution object that can be used to execute a data dependent function on the specified Region.

When invoked from a Geode client, the method returns an Execution instance that sends a message to one of the connected servers as specified by the Pool for the region. Depending on the filters setup on the Execution, the function is executed on all Geode members that define the data region, or a subset of members. Execution::withFilter(filter)).

Parameters

region

If Pool is multiusersecure mode then one need to pass nstance of Region from RegionService.

Returns

Execution

Exceptions

NullPointerException

if the region passed in is nullptr

onServer() [1/2]

static Execution apache::geode::client::FunctionService::onServer ( const std::shared_ptr< Pool > &  pool )

inlinestatic

Returns a Execution object that can be used to execute a data independent function on a server in the provided Pool.

If the server goes down while dispatching or executing the function, an Exception will be thrown.

Parameters

pool	from which to chose a server for execution

Returns

Execution

Exceptions

NullPointerException	if Pool instance passed in is nullptr
UnsupportedOperationException	if Pool is in multiusersecure Mode

onServer() [2/2]

static Execution apache::geode::client::FunctionService::onServer ( RegionService &  regionService )

inlinestatic

Returns a Execution object that can be used to execute a data independent function on a server where Cache is attached.

If the server goes down while dispatching or executing the function, an Exception will be thrown.

Parameters

cache

cache from which to chose a server for execution

Returns

Execution

Exceptions

NullPointerException	if Pool instance passed in is nullptr
UnsupportedOperationException	if Pool is in multiusersecure Mode

onServers() [1/2]

static Execution apache::geode::client::FunctionService::onServers ( const std::shared_ptr< Pool > &  pool )

inlinestatic

Returns a Execution object that can be used to execute a data independent function on all the servers in the provided Pool.

If one of the servers goes down while dispatching or executing the function on the server, an Exception will be thrown.

Parameters

pool	the set of servers to execute the function

Returns

Execution

Exceptions

NullPointerException	if Pool instance passed in is nullptr
UnsupportedOperationException	if Pool is in multiusersecure Mode

onServers() [2/2]

static Execution apache::geode::client::FunctionService::onServers ( RegionService &  regionService )

inlinestatic

Returns a Execution object that can be used to execute a data independent function on all the servers where Cache is attached.

If one of the servers goes down while dispatching or executing the function on the server, an Exception will be thrown.

Parameters

cache

the Cache where function need to execute.

Returns

Execution

Exceptions

NullPointerException	if Pool instance passed in is nullptr
UnsupportedOperationException	if Pool is in multiusersecure Mode
