Modifier and Type	Field and Description
protected DateFormat	_customFormat Specific format to use, if not default format: non null value also indicates that serialization is to be done as JSON String, not numeric timestamp, unless _useTimestamp is true.
protected Boolean	_useTimestamp Flag that indicates that serialization must be done as the Java timestamp, regardless of other settings.

Field Detail

_useTimestamp

protected final Boolean _useTimestamp

Flag that indicates that serialization must be done as the Java timestamp, regardless of other settings.

_customFormat

protected final DateFormat _customFormat

Specific format to use, if not default format: non null value also indicates that serialization is to be done as JSON String, not numeric timestamp, unless _useTimestamp is true.

Constructor Detail

DateTimeSerializerBase

protected DateTimeSerializerBase(Class<T> type,
                      Boolean useTimestamp,
                      DateFormat customFormat)

Method Detail

withFormat

public abstract DateTimeSerializerBase<T> withFormat(Boolean timestamp,
                                   DateFormat customFormat)

createContextual

public JsonSerializer<?> createContextual(SerializerProvider prov,
                                 BeanProperty property)
                                   throws JsonMappingException

Description copied from interface: ContextualSerializer

Method called to see if a different (or differently configured) serializer is needed to serialize values of specified property. Note that instance that this method is called on is typically shared one and as a result method should NOT modify this instance but rather construct and return a new instance. This instance should only be returned as-is, in case it is already suitable for use.

Specified by:

createContextual in interface ContextualSerializer

Parameters:

prov - Serializer provider to use for accessing config, other serializers

property - Method or field that represents the property (and is used to access value to serialize). Should be available; but there may be cases where caller can not provide it and null is passed instead (in which case impls usually pass 'this' serializer as is)

Returns:

Serializer to use for serializing values of specified property; may be this instance or a new instance.

Throws:

JsonMappingException

isEmpty

public boolean isEmpty(T 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.

Overrides:

isEmpty in class JsonSerializer<T>

_timestamp

protected abstract long _timestamp(T value)

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<T>

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<T>

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

Throws:

JsonMappingException

serialize

public abstract void serialize(T value,
             com.fasterxml.jackson.core.JsonGenerator jgen,
             SerializerProvider provider)
                        throws IOException,
                               com.fasterxml.jackson.core.JsonGenerationException

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<T>

Parameters:

value - Value to serialize; can not be null.

jgen - 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

com.fasterxml.jackson.core.JsonGenerationException

_asTimestamp

protected boolean _asTimestamp(SerializerProvider provider)

_acceptJsonFormatVisitor

protected void _acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor,
                            JavaType typeHint,
                            boolean asNumber)
                                 throws JsonMappingException

Throws:

JsonMappingException
