Class ExtendsProcessor

java.lang.Object
org.metricshub.maven.plugin.connector.parser.AbstractNodeProcessor
org.metricshub.maven.plugin.connector.parser.ExtendsProcessor
public class ExtendsProcessor extends AbstractNodeProcessor
The ExtendsProcessor class performs the merging of extended connectors.

This processor is designed to handle the merging of extended connectors specified under the "extends" section of a given JSON node. The merging process involves recursively combining extended connectors and the provided JSON node. The merging logic is implemented in the doMerge(JsonNode) method.

    • merge

      public static com.fasterxml.jackson.databind.JsonNode merge(com.fasterxml.jackson.databind.JsonNode mainNode, com.fasterxml.jackson.databind.JsonNode updateNode)
      Merge the given mainNode and updateNode. Merge strategy:
      1. Arrays of objects are appended from updateNode to mainNode.
      2. Arrays of simple values from updateNode erase the ones in mainNode.
      3. updateNode object values overwrite mainNode object values.
      Parameters:
      mainNode - The main JsonNode to be merged.
      updateNode - The JsonNode containing updates to be merged into the mainNode.
      Returns:
      JsonNode merged
