  PATCH semantics and uses the JSON merge patch format and processing rules.
  
  <p>Sample code:
  
  <pre><code>
  try (InterconnectClient interconnectClient = InterconnectClient.create()) {
  ProjectGlobalInterconnectName interconnect = ProjectGlobalInterconnectName.of("[PROJECT]", "[INTERCONNECT]");
  Interconnect interconnectResource = Interconnect.newBuilder().build();
  List&lt;String&gt; fieldMask = new ArrayList&lt;&gt;();
  Operation response = interconnectClient.patchInterconnect(interconnect, interconnectResource, fieldMask);
  }
  </code></pre>
  
  @param interconnect Name of the interconnect to update.
  @param interconnectResource Represents an Interconnects resource. The Interconnects resource is
  a dedicated connection between Google's network and your on-premises network. For more
  information, see the Dedicated overview page. (== resource_for v1.interconnects ==) (==
  resource_for beta.interconnects ==)
  @param fieldMask The fields that should be serialized (even if they have empty values). If the
  containing message object has a non-null fieldmask, then all the fields in the field mask
  (and only those fields in the field mask) will be serialized. If the containing object does
  not have a fieldmask, then only non-empty fields will be serialized.
  @throws com.google.api.gax.rpc.ApiException if the remote call fails
