Class JSONCoercibleType

java.lang.Object

cascading.nested.json.JSONCoercibleType

All Implemented Interfaces:

cascading.nested.core.NestedCoercibleType<JsonNode,ArrayNode>, cascading.tuple.type.CoercibleType<JsonNode>, cascading.tuple.type.SerializableType, java.io.Serializable, java.lang.reflect.Type

public class JSONCoercibleType
extends java.lang.Object
implements cascading.nested.core.NestedCoercibleType<JsonNode,ArrayNode>, cascading.tuple.type.SerializableType

Class JSONCoercibleType is a NestedCoercibleType that provides support for JSON object types.

Supported values will be maintained as a JsonNode canonical type within the Tuple.

Note that canonical(Object) will always attempt to parse a String value to a new JsonNode. If the parse fails, it will return a TextNode instance wrapping the String value.

Note the default instance (@link TYPE), sets the DeserializationFeature.FAIL_ON_READING_DUP_TREE_KEY Jackson property.

See the NestedCoercibleType.node(Object).
