VariableContext (Camunda Platform Javadocs 7.20.0-SNAPSHOT)

All Known Implementing Classes:

CompositeVariableContext, EmptyVariableContext, SingleVariableContext, VariableMapImpl, VariableScopeContext
```
public interface VariableContext
```
A context for variables. Allows resolving variables. An API may choose to accept a VariableContext instead of a map of concrete values in situations where passing all available variables would be expensive and lazy-loading is a desirable optimization.
