+/**
+ * <p>
+ * A facility to describe simple, common changes to a NiFi flow before it
is installed to the test
+ * NiFi instance. Intended to be used by
+ * {@link
TestNiFiInstance.Builder#modifyFlowXmlBeforeInstalling(FlowFileEditorCallback)}
+ * </p>
+ *
+ * <p>
+ * The desired edits can be configured via the {@link Builder} object
returned by the {@link #builder()}
+ * method. Once fully configured, the {@link Builder#build()} emits a
{@code FlowFileEditorCallback}
+ * object that can be passed to
+ * {@link
TestNiFiInstance.Builder#modifyFlowXmlBeforeInstalling(FlowFileEditorCallback)}.
+ * </p>
+ *
+ * <p>
+ * <strong>CAUTION: THIS IS AN EXPERIMENTAL API: EXPECT CHANGES!</strong>
+ * Efforts will be made to retain backwards API compatibility, but
+ * no guarantee is given.
+ * </p>
