Class StartProcessVariableScope

java.lang.Object

org.activiti.engine.impl.el.StartProcessVariableScope

All Implemented Interfaces:

VariableScope

public class StartProcessVariableScope
extends Object
implements VariableScope

Variable-scope only used to resolve variables when NO execution is active but expression-resolving is needed. This occurs eg. when start-form properties have default's defined. Even though variables are not available yet, expressions should be resolved anyway.

Methods

Modifier and Type	Method and Description
void	createVariableLocal(String variableName, Object value)
void	createVariablesLocal(Map<String,? extends Object> variables)
static StartProcessVariableScope	getSharedInstance() Since a StartProcessVariableScope has no state, it's safe to use the same instance to prevent too many useless instances created.
Object	getVariable(String variableName)
Object	getVariableLocal(String variableName)
Set<String>	getVariableNames()
Set<String>	getVariableNamesLocal()
Map<String,Object>	getVariables()
Map<String,Object>	getVariablesLocal()
boolean	hasVariable(String variableName)
boolean	hasVariableLocal(String variableName)
boolean	hasVariables()
boolean	hasVariablesLocal()
void	removeVariable(String variableName) Removes the variable and creates a new HistoricVariableUpdateEntity.
void	removeVariableLocal(String variableName) Removes the local variable and creates a new HistoricVariableUpdateEntity.
void	removeVariables() Removes the (local) variables and creates a new HistoricVariableUpdateEntity for each of them.
void	removeVariables(Collection<String> variableNames) Removes the variables and creates a new HistoricVariableUpdateEntity for each of them.
void	removeVariablesLocal() Removes the (local) variables and creates a new HistoricVariableUpdateEntity for each of them.
void	removeVariablesLocal(Collection<String> variableNames) Removes the local variables and creates a new HistoricVariableUpdateEntity for each of them.
void	setVariable(String variableName, Object value)
