Returns:

the reader

nodeFactory

public static JsonNodeFactory nodeFactory()

Return a preconfigured JsonNodeFactory to generate JSON data as JsonNodes

Returns:

the factory

asMap

public static Map<String,JsonNode> asMap(JsonNode node)

Return a map out of an object's members

If the node given as an argument is not a map, an empty map is returned.

Parameters:

node - the node

newMapper

public static ObjectMapper newMapper()

Return a preconfigured ObjectMapper

The returned mapper will have the following features enabled:

• DeserializationFeature.USE_BIG_DECIMAL_FOR_FLOATS;
• JsonGenerator.Feature.WRITE_BIGDECIMAL_AS_PLAIN;
• SerializationFeature.INDENT_OUTPUT.

This returns a new instance each time.

Returns:

an ObjectMapper
