Search Results for "wrap"

...The traditional error handling idiom in Go that is applied recursively up the call stack results in error reports without context or debugging information. The errors package allows programmers to add context to the failure path in their code in a way that does not destroy the original value of the error. Wrap function returns a new error that adds context to the original error. Using errors.Wrap constructs a stack of errors, adding context to the preceding error. Depending on the nature of the error it may be necessary to reverse the operation of errors.Wrap to retrieve the original error for inspection. Any error value which implements this interface can be inspected by errors.Cause. errors.Cause will recursively retrieve the topmost error which does not implement causer, which is assumed to be the original cause.

JdbcProxy is a JDBC 2.0 driver that can help debug or test applications. The driver can wrap another JDBC driver to debug the JDBC calls done by the application. The driver can also emulate another JDBC driver to test the application without a database.

WrapLog is a tiny Java logging package that can "wrap" around other logging packages, thus removing the need to stick to a certain one. This is particular useful for Java libraries that want to leave the choice for a logging packing to the client code.
