Examples of org.jbpm.context.exe.ContextInstance

org.jbpm.context.exe.ContextInstance
Maintains all the key-variable pairs for a process instance. You can obtain a ContextInstance from a processInstance from a process instance like this :
```
 ProcessInstance processInstance = ...; ContextInstance contextInstance = processInstance.getContextInstance(); 
```

            boolean updated = false;


            final Object targetValue = targetExpression.getValue(elContext);
            if (targetValue instanceof ProcessInstance) {
                final ProcessInstance processInstance = (ProcessInstance) targetValue;
                final ContextInstance contextInstance = processInstance.getContextInstance();
                for (String name : deletes) {
                    contextInstance.deleteVariable(name);
                    updated = true;
                }
                for (String name : updates) {
                    contextInstance.setVariable(name, updatesHashMap.get(name));
                    updated = true;
                }
            } else if (targetValue instanceof Token) {
                final Token token = (Token) targetValue;
                final ProcessInstance processInstance = token.getProcessInstance();
                final ContextInstance contextInstance = processInstance.getContextInstance();
                for (String name : deletes) {
                    contextInstance.deleteVariable(name, token);
                    updated = true;
                }
                for (String name : updates) {
                    contextInstance.setVariable(name, updatesHashMap.get(name), token);
                    updated = true;
                }
            } else if (targetValue instanceof TaskInstance) {
                final TaskInstance task = (TaskInstance) targetValue;
