Method Detail

• getName

  public abstract String getName()

• getFullName

  public abstract PropertyName getFullName()

• findAnnotation

  public <A extends Annotation> A findAnnotation(Class<A> acls)

  Convenience method for accessing annotation that may be associated either directly on property, or, if not, via enclosing class (context). This allows adding baseline contextual annotations, for example, by adding an annotation for a given class and making that apply to all properties unless overridden by per-property annotations.

  This method is functionally equivalent to:

    MyAnnotation ann = propWriter.getAnnotation(MyAnnotation.class);
    if (ann == null) {
      ann = propWriter.getContextAnnotation(MyAnnotation.class);
    }
  

  that is, tries to find a property annotation first, but if one is not found, tries to find context-annotation (from enclosing class) of same type.

  2.5

• getAnnotation

  public abstract <A extends Annotation> A getAnnotation(Class<A> acls)

  Method for accessing annotations directly declared for property that this writer is associated with.

  Since:

  2.5

• getContextAnnotation

  public abstract <A extends Annotation> A getContextAnnotation(Class<A> acls)

  Method for accessing annotations declared in context of the property that this writer is associated with; usually this means annotations on enclosing class for property.

  Since:

  2.5

• serializeAsField

  public abstract void serializeAsField(Object value,
                      JsonGenerator jgen,
                      SerializerProvider provider)
                                 throws Exception

  The main serialization method called by filter when property is to be written normally.

  Throws:

  Exception

• serializeAsOmittedField

  public abstract void serializeAsOmittedField(Object value,
                             JsonGenerator jgen,
                             SerializerProvider provider)
                                        throws Exception

  Serialization method that filter needs to call in cases where property is to be filtered, but the underlying data format requires a placeholder of some kind. This is usually the case for tabular (positional) data formats such as CSV.

  Throws:

  Exception

• serializeAsElement

  public abstract void serializeAsElement(Object value,
                        JsonGenerator jgen,
                        SerializerProvider provider)
                                   throws Exception

  Serialization method called when output is to be done as an array, that is, not using property names. This is needed when serializing container (Collection, array) types, or POJOs using tabular ("as array") output format.

  Note that this mode of operation is independent of underlying data format; so it is typically NOT called for fully tabular formats such as CSV, where logical output is still as form of POJOs.

  Throws:

  Exception

• serializeAsPlaceholder

  public abstract void serializeAsPlaceholder(Object value,
                            JsonGenerator jgen,
                            SerializerProvider provider)
                                       throws Exception

  Serialization method called when doing tabular (positional) output from databind, but then value is to be omitted. This requires output of a placeholder value of some sort; often similar to serializeAsOmittedField(java.lang.Object, com.fasterxml.jackson.core.JsonGenerator, com.fasterxml.jackson.databind.SerializerProvider).

  Throws:

  Exception

• depositSchemaProperty

  public abstract void depositSchemaProperty(JsonObjectFormatVisitor objectVisitor)
                                      throws JsonMappingException

  Traversal method used for things like JSON Schema generation, or POJO introspection.

  Throws:

  JsonMappingException

• depositSchemaProperty

  @Deprecated
  public abstract void depositSchemaProperty(ObjectNode propertiesNode,
                                      SerializerProvider provider)
                                      throws JsonMappingException

  Deprecated. Since 2.2
  Legacy method called for JSON Schema generation; should not be called by new code

  Throws:

  JsonMappingException
