java.lang.Object

com.fasterxml.jackson.databind.JsonSerializer<T>

com.fasterxml.jackson.databind.ser.std.StdSerializer<char[]>

com.fasterxml.jackson.databind.ser.std.StdArraySerializers.CharArraySerializer

All Implemented Interfaces:

JsonFormatVisitable, SchemaAware, Serializable

Enclosing class:

StdArraySerializers

public static class StdArraySerializers.CharArraySerializer
extends StdSerializer<char[]>

Character arrays are different from other integral number arrays in that they are most likely to be textual data, and should be written as Strings, not arrays of entries.

NOTE: since it is NOT serialized as an array, cannot use AsArraySerializer as base

boolean	isEmpty(SerializerProvider prov, char[] value)	Method called to check whether given serializable value is considered "empty" value (for purposes of suppressing serialization of empty values).
void	serialize(char[] value, JsonGenerator g, SerializerProvider provider)	Method that can be called to ask implementation to serialize values of type this serializer handles.
void	serializeWithType(char[] value, JsonGenerator g, SerializerProvider provider, TypeSerializer typeSer)	Method that can be called to ask implementation to serialize values of type this serializer handles, using specified type serializer for embedding necessary type information.

Method Detail

isEmpty

public boolean isEmpty(SerializerProvider prov,
                       char[] value)

Description copied from class: JsonSerializer

Method called to check whether given serializable value is considered "empty" value (for purposes of suppressing serialization of empty values).

Default implementation will consider only null values to be empty.

NOTE: replaces JsonSerializer.isEmpty(Object), which was deprecated in 2.5

Overrides:

isEmpty in class JsonSerializer<char[]>

serialize

public void serialize(char[] value,
                      JsonGenerator g,
                      SerializerProvider provider)
               throws IOException

Description copied from class: JsonSerializer

Method that can be called to ask implementation to serialize values of type this serializer handles.

Specified by:

serialize in class StdSerializer<char[]>

Parameters:

value - Value to serialize; can not be null.

g - Generator used to output resulting Json content

provider - Provider that can be used to get serializers for serializing Objects value contains, if any.

Throws:

IOException

serializeWithType

public void serializeWithType(char[] value,
                              JsonGenerator g,
                              SerializerProvider provider,
                              TypeSerializer typeSer)
                       throws IOException

Description copied from class: JsonSerializer

Method that can be called to ask implementation to serialize values of type this serializer handles, using specified type serializer for embedding necessary type information.

Default implementation will throw UnsupportedOperationException to indicate that proper type handling needs to be implemented.

For simple datatypes written as a single scalar value (JSON String, Number, Boolean), implementation would look like:

  // note: method to call depends on whether this type is serialized as JSON scalar, object or Array!
  typeSer.writeTypePrefixForScalar(value, gen);
  serialize(value, gen, provider);
  typeSer.writeTypeSuffixForScalar(value, gen);

and implementations for type serialized as JSON Arrays or Objects would differ slightly, as START-ARRAY/END-ARRAY and START-OBJECT/END-OBJECT pairs need to be properly handled with respect to serializing of contents.

Overrides:

serializeWithType in class JsonSerializer<char[]>

Parameters:

value - Value to serialize; can not be null.

g - Generator used to output resulting Json content

provider - Provider that can be used to get serializers for serializing Objects value contains, if any.

typeSer - Type serializer to use for including type information

Throws:

IOException

getSchema

public JsonNode getSchema(SerializerProvider provider,
                          Type typeHint)

Description copied from class: StdSerializer

Default implementation simply claims type is "string"; usually overriden by custom serializers.

Specified by:

getSchema in interface SchemaAware

Overrides:

getSchema in class StdSerializer<char[]>

Parameters:

provider - The serializer provider.

typeHint - A hint about the type.

Returns:

Json-schema for this serializer.

acceptJsonFormatVisitor

public void acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor,
                                    JavaType typeHint)
                             throws JsonMappingException

Description copied from class: StdSerializer

Default implementation specifies no format. This behavior is usually overriden by custom serializers.

Specified by:

acceptJsonFormatVisitor in interface JsonFormatVisitable

Overrides:

acceptJsonFormatVisitor in class StdSerializer<char[]>

typeHint - Type of element (entity like property) being visited

Throws:

JsonMappingException
