Method Detail

isNull

default boolean isNull()

Returns:

True if the node represents an explicit JSON null, false otherwise.

asText

default String asText()

Returns:

The value of the node as text. Returns null for most nodes except for SdkScalarNode.

embeddedObject

Returns:

The embedded object value of the node. See SdkEmbeddedObject.

get

default SdkJsonNode get(String fieldName)

Parameters:

fieldName - Field to get value for.

Returns:

Value of field in the JSON object if this node represents an object, otherwise returns null.

items

default List<SdkJsonNode> items()

Returns:

If this node represents a JSON array, then this returns the list of items in that array. Otherwise returns null.
