execute() [1/2]

std::shared_ptr<ResultCollector> apache::geode::client::Execution::execute	(	const std::shared_ptr< CacheableVector > &	routingObj,
		const std::shared_ptr< Cacheable > &	args,
		const std::shared_ptr< ResultCollector > &	rs,
		const std::string &	func,
		std::chrono::milliseconds	timeout
	)

Executes the function using its name.

Parameters

routingObj	Set defining the data filter to be used for executing the function
args	user data passed to the function execution
rs	* Specifies the ResultCollector that will receive the results after the function has been executed.
func	the name of the function to be executed
timeout	value to wait for the operation to finish before timing out.

Exceptions

Exception

if there is an error during function execution

Returns

either a default result collector or one specified by {}

execute() [2/2]

std::shared_ptr<ResultCollector> apache::geode::client::Execution::execute	(	const std::string &	func,
		std::chrono::milliseconds	timeout = DEFAULT_QUERY_RESPONSE_TIMEOUT
	)

Executes the function using its name.

Parameters

func	the name of the function to be executed
timeout	value to wait for the operation to finish before timing out.

Exceptions

Exception

if there is an error during function execution

Returns

either a default result collector or one specified by {}

withArgs()

Execution apache::geode::client::Execution::withArgs

(

std::shared_ptr< Cacheable >

args

)

Specifies the user data passed to the function when it is executed.

Parameters

args	user data passed to the function execution

Returns

an Execution with args

Exceptions

IllegalArgumentException

if the input parameter is nullptr

withCollector()

Execution apache::geode::client::Execution::withCollector

(

std::shared_ptr< ResultCollector >

rs

)

Specifies the ResultCollector that will receive the results after the function has been executed.

Returns

an Execution with a collector

Exceptions

IllegalArgumentException

if ResultCollector is nullptr

withFilter()

Execution apache::geode::client::Execution::withFilter

(

std::shared_ptr< CacheableVector >

routingObj

)

Specifies a data filter of routing objects for selecting the Geode members to execute the function.

If the filter set is empty the function is executed on all members that have the FunctionService::onRegion(Region).

Parameters

routingObj

Set defining the data filter to be used for executing the function

Returns

an Execution with the filter

Exceptions

IllegalArgumentException	if filter passed is nullptr.
UnsupportedOperationException	if not called after FunctionService::onRegion(Region).
