## 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.
