Method Detail

patch

public com.datastax.driver.core.Session patch(com.datastax.driver.core.Session session)

Description copied from class: DDAgentTracingHelper

This method takes an object and applies some mutation in order to add tracing capabilities. This method should never return any Exception in order to not stop the app traced.

This method should be defined as final, but something Byteman need to define this one with the explicit type (i.e. without using generic), so this is why we don't use final here.

Overrides:

patch in class DDAgentTracingHelper<com.datastax.driver.core.Session>

Parameters:

session - The object to patch, the type is defined by the subclass instantiation

Returns:

The object patched
