Method Detail

createObjectMapper

public static ObjectMapper createObjectMapper()

creates a new ObjectMapper instance

Returns:

ObjectMapper

createObjectMapper

public static ObjectMapper createObjectMapper(ModuleOptions options)

Parameters:

options - configuration for jackson modules supplied by a ModuleSupplier

Returns:

ObjectMapper

toJsonByteArray

public static byte[] toJsonByteArray(Object value)
                              throws com.fasterxml.jackson.core.JsonProcessingException

serializes the given object to JSON as a byte array

Parameters:

value - object to be serialized

Returns:

json byte array

Throws:

com.fasterxml.jackson.core.JsonProcessingException - serialization errors

toJsonString

public static String toJsonString(Object value)
                           throws com.fasterxml.jackson.core.JsonProcessingException

serializes the given object to JSON as a byte array

Parameters:

value - object to be serialized

Returns:

json string

Throws:

com.fasterxml.jackson.core.JsonProcessingException - serialization errors

fromJsonString

public static <T> T fromJsonString(String content,
                                   Class<T> clazz)

deserializes the given json string to the given class

Type Parameters:

T - type of the result

Parameters:

clazz - class to serialize to

content - json as string

Returns:

deserialized object

fromJsonString

public static <T> T fromJsonString(String jsonAsString,
                                   com.fasterxml.jackson.core.type.TypeReference<T> typeReference)

Reads a Java object from JSON data (String).

Type Parameters:

T - the type of the result

Parameters:

jsonAsString - the JSON data which represents sth. of type <T>

typeReference - the full generic type information about the object to create

Returns:

the created objected

fromJsonNode

public static <T> T fromJsonNode(JsonNode jsonNode,
                                 com.fasterxml.jackson.core.type.TypeReference<T> typeReference)

Reads a Java object from JsonNode data.

Type Parameters:

T - the type of the result

Parameters:

jsonNode - the JSON data which represents sth. of type <T>

typeReference - the full generic type information about the object to create

Returns:

the created objected

toJsonNode

public static JsonNode toJsonNode(Object value)

Converts a commercetools Composable Commerce Java object to JSON as JsonNode.

If value is of type String and contains JSON data, that will be ignored, value will be treated as just any String. If you want to parse a JSON String to a JsonNode use parse(java.lang.String) instead.

Parameters:

value - the object to convert

Returns:

new json

parse

default ObjectMapper

Returns:

ObjectMapper

prettyPrint

public static String prettyPrint(String json)

Pretty prints a given JSON string.

Parameters:

json - JSON code as String which should be formatted
