Interface JCoFunctionUnit

public interface JCoFunctionUnit

The interface comprises public methods to work with function unit. Function unit is used as function container in bgRFC calls. It contains one or more functions and may defines queues to ensure execution order.

Note: The implementation for this interface provided by the JCo runtime. Other implementations are not supported.

Method Summary

Methods

Modifier and Type	Method and Description
void	addFunction(JCoFunction function) Adds a function to the unit.
void	addFunctions(List<JCoFunction> functions) Adds the functions to the unit.
boolean	addQueueName(String queueName) Adds a queue name.
boolean	addQueueNames(Set<String> queueNames) Adds the given queue names.
void	commit(JCoDestination destination) Commits the unit.
List<JCoFunction>	getFunctions() Returns an immutable list of function.
JCoUnitIdentifier	getIdentifier() Return the unique identifier for the function unit.
Set<String>	getQueueNames() Returns an immutable copy of the list containing the queue names.

Method Detail

getIdentifier

JCoUnitIdentifier getIdentifier()

Return the unique identifier for the function unit.

Returns:

the unit identifier

addQueueName

boolean addQueueName(String queueName)

Adds a queue name.

Parameters:

queueName - name of the queue

Returns:

true, if the queue name is added, false if the name is already in the list

Throws:

JCoRuntimeException - if the unit is being modified after commit

JCoRuntimeException - if the queue name is not allowed. Allowed are queue names [A-Z]([A-Z]|[0-9]|_)* only.

addQueueNames

boolean addQueueNames(Set<String> queueNames)

Adds the given queue names.

Parameters:

queueNames - set of the queue names to add

Returns:

true, if all queue names are added, false if a name is already in the list

Throws:

JCoRuntimeException - if the unit is being modified after commit

JCoRuntimeException - if a queue name in the list is not allowed. Allowed are queue names [A-Z]([A-Z]|[0-9]|_)* only.

getQueueNames

Set<String> getQueueNames()

Returns an immutable copy of the list containing the queue names.

Returns:

the list of the queue names

addFunction

void addFunction(JCoFunction function)

Adds a function to the unit.
Note: the function shall not be changed before commit.

Parameters:

function - function to be added to the function unit

Throws:

JCoRuntimeException - if the unit is being modified after commit

addFunctions

void addFunctions(List<JCoFunction> functions)

Adds the functions to the unit.
Note: the functions shall not be changed before commit.

Parameters:

functions - list of functions to be added to the function unit

Throws:

JCoRuntimeException - if the unit is being modified after commit

getFunctions

List<JCoFunction> getFunctions()

Returns an immutable list of function.

Returns:

the list of the functions

commit

void commit(JCoDestination destination)
            throws JCoException

Commits the unit. After commit the unit cannot be changed. It is allowed to invoke commit more than once in case of exceptions.

Parameters:

destination - to which the unit has to be send

Throws:

JCoException - if transmission or processing on the remote side fails
