Class StartProcessVariableScope

java.lang.Object
  org.camunda.bpm.engine.impl.el.StartProcessVariableScope

All Implemented Interfaces:

VariableScope<CoreVariableInstance>

public class StartProcessVariableScope
extends Object
implements VariableScope<CoreVariableInstance>

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.

StartProcessVariableScope()

Method Summary

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)
CoreVariableInstance	getVariableInstance(String name) Returns a single variable instance from either this scope or any of its parents.
CoreVariableInstance	getVariableInstanceLocal(String name) Returns a single variable instance that this scope holds.
Map<String,CoreVariableInstance>	getVariableInstances() Returns this scope's and its parent's (grandparents etc.) variables as variable instance objects.
Map<String,CoreVariableInstance>	getVariableInstancesLocal() Returns the variable instances that this scope holds.
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)
