							|  |  |  | ## Intent
 | 
					
						
							| 
									
										
										
										
											2016-07-21 09:27:48 +03:00
										 |  |  | Provide a template to suppress any exceptions that either are declared but cannot occur or should only be logged; | 
					
						
							| 
									
										
										
										
											2016-03-26 13:54:03 +05:30
										 |  |  | while executing some business logic. The template removes the need to write repeated `try-catch` blocks. |

 | 
					
						
							|  |  |  | ## Applicability
 | 
					
						
							|  |  |  | Use this idiom when | 
					
						
							|  |  |  | 
 | 
					
						
							| 
									
										
										
										
											2016-07-21 09:27:48 +03:00
										 |  |  | * an API declares some exception but can never throw that exception eg. ByteArrayOutputStream bulk write method. | 
					
						
							| 
									
										
										
										
											2016-03-26 13:54:03 +05:30
										 |  |  | * you need to suppress some exception just by logging it, such as closing a resource. |
