Method Detail

initVariablesFromProperties

public void initVariablesFromProperties(org.flowable.engine.delegate.DelegateExecution execution)

Use this method to initialize variables through the specific init Variable service task. It assumes the configuration to be part of the service task definition requested through the execution provided. Both variable names and values might be EL expressions and if so, will be evaluated before initializing the variable

Parameters:

execution - the activity execution context

initQueryListVariablesFromProperties

public void initQueryListVariablesFromProperties(org.flowable.engine.delegate.DelegateExecution execution)

Use this method to initialize variables on a result list of work objects given by a query string and variable properties. This method is similar to #initVariablesFromProperties, however, instead of the current process instance context, the work objects to apply the variables to, are taken from executing a query.

Parameters:

execution - the activity execution context

initVariables

public void initVariables(org.flowable.engine.delegate.DelegateExecution execution,
                          Object... variableNamesAndValues)

Use this method to initialize variables, if they have not yet been set on the process scope. Use the following expression within a service task in the process: ` #{processVariables.initVariables(execution,"variableName1","fixedVariable1Value","variableName1",owner.id.value)} `

Parameters:

execution - the activity execution context

variableNamesAndValues - the variable names and values.

setVariables

public void setVariables(org.flowable.engine.delegate.DelegateExecution execution,
                         Object... variableNamesAndValues)

Use this method to set variables, even if they have been set on the process scope already, they will be overwritten. Use the following expression within a service task in the process: ` #{processVariables.setVariables(execution,"variableName1","fixedVariable1Value","variableName1",owner.id.value)} `

Parameters:

execution - the activity execution context

variableNamesAndValues - the variable names and values.

expandReferencedVariables

public void expandReferencedVariables(org.flowable.engine.delegate.DelegateExecution execution,
                                      String... variableNames)

Use this method to expand variables with a referenced work item id. Use the following expression within a service task in the process: ` #{processVariables.expandReferencedVariables(execution,"workItemRefId1","targetVariableName1","propertyNameOnRef1","workItemRefId2","targetVariableName2", "propertyNameOnRef2")} `

Parameters:

execution - the activity execution context

variableNames - the variable names.
