modifyException

public Throwable modifyException(Context.FailedExecution context,
 ExecutionAttributes executionAttributes)

Description copied from interface: ExecutionInterceptor

Modify the exception before it is thrown.

Specified by:

modifyException in interface ExecutionInterceptor

Parameters:

context - The context associated with the execution that failed. An SDK request will always be available, but depending on the time at which the failure happened, the HTTP request, HTTP response and SDK response may not be available. This also includes the exception that triggered the failure.

executionAttributes - A mutable set of attributes scoped to one specific request/response cycle that can be used to give data to future lifecycle methods.

Returns:

the modified Exception
