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.

                JsonNode data = result.path("data");
                assertTrue(data.path("integer").isIntegralNumber());
                assertTrue(data.path("double").isDouble());
                assertTrue(data.path("text").isTextual());
                assertTrue(data.path("obj").isObject());
                assertTrue(data.path("ary").isArray());
                assertTrue(data.path("no").isNull());
                assertTrue(data.path("date").asText().startsWith(Year.now().toString()));
                assertEquals("custom", data.path("custom").path("val").asText());
