Represents a variable scope. This is primarily used to determine variable sharing across method and closure boundaries. @author James Strachan @author Jochen Theodorou @version $Revision: 17917 $

org.jbpm.pvm.VariableScope
a scope of variables {@link Execution#getVariableScopeIterator() associated to an execution}.
Users should use the convenience methods on execution
- {@link Execution#getVariable(String)}
- {@link Execution#getVariableKeys()}
- {@link Execution#getVariables()}
- {@link Execution#setVariable(String,Object)}
- {@link Execution#setVariables(Map)}
This interface is created so that process languages can embed their variable scopes in other objects. E.g. by default, the ExecutionImpl class manages a list of VariableScope's. But the execution subclass for individual process languages can overwrite the usage of that member and get the variable scopes from some other member.
