Class com.fasterxml.jackson.databind.JsonNode

Examples of com.fasterxml.jackson.databind.JsonNode.path()

com.fasterxml.jackson.databind.JsonNode.path()
This method is similar to {@link #get(String)}, except that instead of returning null if no such value exists (due to this node not being an object, or object not having value for the specified field), a "missing node" (node that returns true for {@link #isMissingNode}) will be returned. This allows for convenient and safe chained access via path calls.
