  - insert
```
default RhsContext insert(Object obj)
```
    Parameters:
    
    obj - fact to insert
    
    Returns:
    
    RHS context

  - insert
```
RhsContext insert(Object fact,
                  boolean resolveCollections)
```
    Buffers a new insert operation in rule's memory
    
    Parameters:
    
    fact - object to insert
    
    resolveCollections - collection/array inspection flag
    
    Returns:
    
    RHS context
    
    Throws:
    
    NullPointerException - if argument is null
  - insert
```
default RhsContext insert(Collection<?> objects)
```
  - insert
```
default RhsContext insert(Object[] objects)
```
  - update
```
RhsContext update(Object obj)
```
    This method lets the working memory know that one of its objects has changed. Always call this method to get conditions re-evaluated, and avoid calling it if the changes are not relevant to the conditions.
    
    Parameters:
    
    obj - the changed object
    
    Returns:
    
    the context itself so the methods could be chained
  - delete
```
RhsContext delete(Object obj)
```
    This method removes an instance from the working memory.
    
    Parameters:
    
    obj - the object to remove
    
    Returns:
    
    the context itself so the methods could be chained
  - getRule
```
RuntimeRule getRule()
```
    A convenience method that returns reference to the current rule and its environment.
    
    Returns:
    
    current rule
  - getRuntime
```
default RuleSession<?> getRuntime()
```
    Provides access to the runtime context, an equivalent to getRule().getRuntime().
    
    Returns:
    
    runtime context (session)
  - deleteFact
```
default RhsContext deleteFact(String factRef)
```
  - updateFact
```
default RhsContext updateFact(String factRef)
```
  - getObject
```
Object getObject(String name)
```
    Returns current fact by its name
    
    Parameters:
    
    name - the fact name
    
    Returns:
    
    current instance
  - get
```
default <T> T get(String name)
```
    A typed version of the getObject() method.
    
    Type Parameters:
    
    T - cast type
    
    Parameters:
    
    name - fact name
    
    Returns:
    
    current instance
  - get
```
default <T> T get(Class<T> type,
                  String name)
```
    A typed version of the get() method with explicit generic cast type.
    
    Type Parameters:
    
    T - cast type
    
    Parameters:
    
    name - fact name
    
    type - fact type
    
    Returns:
    
    current instance
