Method Details
- getRhs
  
  Consumer<RhsContext> getRhs()
  
  Gets the RHS (Right Hand Side) logic as a Consumer.
  
  Returns:
  
  the RHS logic consumer.
- setRhs
  
  void setRhs(String literalRhs)
  
  Sets the RHS logic using a literal string. The literal will be compiled and converted into a Consumer.
  
  Parameters:
  
  literalRhs - the string representation of RHS logic.
- setRhs
  
  void setRhs(Consumer<RhsContext> rhs)
  
  Sets the RHS logic using a Consumer. Can be null.
  
  Parameters:
  
  rhs - the RHS logic consumer.
- getSalience
  
  int getSalience()
  
  Retrieves the rule's salience.
  
  Returns:
  
  the salience value.
- setSalience
  
  void setSalience(int value)
  
  Sets the rule's salience.
  
  Parameters:
  
  value - the salience value to set.
- chainRhs
  
  void chainRhs(Consumer<RhsContext> consumer)
  
  Chains a consumer to the current RHS logic. The provided consumer is executed after the current RHS.
  
  Parameters:
  
  consumer - the consumer to chain.
- setName
  
  void setName(String newName)
  
  Sets a new name for the rule.
  
  Parameters:
  
  newName - the new name to give to the rule.
