Method Detail

patch

public org.apache.http.impl.client.HttpClientBuilder patch(org.apache.http.impl.client.HttpClientBuilder builder)

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<org.apache.http.impl.client.HttpClientBuilder>

Parameters:

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

Returns:

The object patched

doPatch

protected org.apache.http.impl.client.HttpClientBuilder doPatch(org.apache.http.impl.client.HttpClientBuilder builder)
                                                         throws Exception

Strategy: We replace the legacy builder by a new instance providing by the opentracing contribution when the builder is instantiate. @see org.apache.http.impl.client.HttpClientBuilder.create() method

Specified by:

doPatch in class DDAgentTracingHelper<org.apache.http.impl.client.HttpClientBuilder>

Parameters:

builder - The legacy builder instance

Returns:

A tracing builder instance (new reference)

Throws:

Exception
