Package org.bonitasoft.engine.expression

Class ParameterExpressionExecutorStrategy

java.lang.Object

org.bonitasoft.engine.expression.NonEmptyContentExpressionExecutorStrategy

org.bonitasoft.engine.expression.ParameterExpressionExecutorStrategy

All Implemented Interfaces:

ExpressionExecutorStrategy

public class ParameterExpressionExecutorStrategy
extends NonEmptyContentExpressionExecutorStrategy

Retrieve a String parameter from the ParameterService. The content of the expression must be the parameter name, as a String. The dependency map must contain a value for 'processDefinitionId' key to identify the process definition context to evaluate the parameter.
