Method Detail

internalInitVariables

protected void internalInitVariables(org.activiti.engine.delegate.DelegateExecution execution,
                         Object variableResolutionContext)

handleVariableInitialization

protected void handleVariableInitialization(com.edorasware.commons.core.entity.WorkObject<?,?,?> workObjectInScope,
                                org.activiti.engine.delegate.DelegateExecution execution,
                                Map<String,Object> additionalContext,
                                Object variableResolutionContext,
                                InitVariableData initVariableData)

Uses the given arguments to initialize the given variable. The variable value as well as the target name might be expressions and if so will be evaluated before used. The variable name must not be null and is expected to be a string literal rather than an expression.

Parameters:

workObjectInScope - the work object in scope.

execution - the delegate execution.

additionalContext - the additional context.

variableResolutionContext - the variable resolution context.

initVariableData - the init variable data.

getVariableName

protected String getVariableName(com.edorasware.commons.core.entity.WorkObject<?,?,?> workObjectInScope,
