Class StringSerializer

All Implemented Interfaces:
JsonFormatVisitable, SchemaAware, Serializable

public final class StringSerializer extends StdScalarSerializer<Object>
This is the special serializer for regular Strings.

Since this is one of "native" types, no type information is ever included on serialization (unlike for most scalar types as of 1.5)

    • isEmpty

      public boolean isEmpty(SerializerProvider prov, Object 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<Object>
    • serialize

      public void serialize(Object value, com.fasterxml.jackson.core.JsonGenerator gen, 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<Object>
      Parameters:
      value - Value to serialize; can not be null.
      gen - 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 final void serializeWithType(Object value, com.fasterxml.jackson.core.JsonGenerator gen, SerializerProvider provider, TypeSerializer typeSer) throws IOException
      Description copied from class: StdScalarSerializer
      Default implementation will write type prefix, call regular serialization method (since assumption is that value itself does not need JSON Array or Object start/end markers), and then write type suffix. This should work for most cases; some sub-classes may want to change this behavior.
      Overrides:
      serializeWithType in class StdScalarSerializer<Object>
      Parameters:
      value - Value to serialize; can not be null.
      gen - 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 StdScalarSerializer<Object>
      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 StdScalarSerializer<Object>
      typeHint - Type of element (entity like property) being visited
      Throws:
      JsonMappingException
