PromptTemplate

All Implemented Interfaces:
```
public class PromptTemplate

                    
```
Represents a template of a prompt that can be reused multiple times. A template typically contains one or more variables (placeholders) defined as {{variable_name}} that are replaced with actual values to produce a Prompt. Special variables {{current_date}}, {{current_time}}, and {{current_date_time}} are automatically filled with LocalDate.now(), LocalTime.now(), and LocalDateTime.now() respectively.
