createContextual
public JsonSerializer<?> createContextual(SerializerProvider provider, 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 interfaceContextualSerializer
- Parameters:
provider
- Serializer provider to use for accessing config, other serializersproperty
- 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 cannot 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
-
getContentType
public JavaType getContentType()
Description copied from class:ContainerSerializer
Accessor for finding declared (static) element type for type this serializer is used for.- Specified by:
getContentType
in classContainerSerializer<java.util.Map<?,?>>
-
getContentSerializer
public JsonSerializer<?> getContentSerializer()
Description copied from class:ContainerSerializer
Accessor for serializer used for serializing contents (List and array elements, Map values etc) of the container for which this serializer is used, if it is known statically. Note that for dynamic types this may return null; if so, caller has to instead useContainerSerializer.getContentType()
andSerializerProvider.findContentValueSerializer(com.fasterxml.jackson.databind.JavaType, com.fasterxml.jackson.databind.BeanProperty)
.- Specified by:
getContentSerializer
in classContainerSerializer<java.util.Map<?,?>>
-
isEmpty
public boolean isEmpty(SerializerProvider prov, java.util.Map<?,?> 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 classJsonSerializer<java.util.Map<?,?>>
-
hasSingleElement
public boolean hasSingleElement(java.util.Map<?,?> value)
Description copied from class:ContainerSerializer
Method called to determine if the given value (of type handled by this serializer) contains exactly one element.Note: although it might seem sensible to instead define something like "getElementCount()" method, this would not work well for containers that do not keep track of size (like linked lists may not).
Note, too, that as of now (2.9) this method is only called by serializer itself; and specifically is not used for non-array/collection types like
Map
orMap.Entry
instances.- Specified by:
hasSingleElement
in classContainerSerializer<java.util.Map<?,?>>
-
getKeySerializer
public JsonSerializer<?> getKeySerializer()
Accessor for currently assigned key serializer. Note that this may return null during construction ofMapSerializer
: depedencies are resolved duringcreateContextual(com.fasterxml.jackson.databind.SerializerProvider, com.fasterxml.jackson.databind.BeanProperty)
method (which can be overridden by custom implementations), but for some dynamic types, it is possible that serializer is only resolved during actual serialization.
-
serialize
public void serialize(java.util.Map<?,?> value, com.fasterxml.jackson.core.JsonGenerator gen, SerializerProvider provider) throws java.io.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 classStdSerializer<java.util.Map<?,?>>
- Parameters:
value
- Value to serialize; can not be null.gen
- Generator used to output resulting Json contentprovider
- Provider that can be used to get serializers for serializing Objects value contains, if any.- Throws:
java.io.IOException
-
serializeWithType
public void serializeWithType(java.util.Map<?,?> value, com.fasterxml.jackson.core.JsonGenerator gen, SerializerProvider provider, TypeSerializer typeSer) throws java.io.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, asSTART-ARRAY
/END-ARRAY
andSTART-OBJECT
/END-OBJECT
pairs need to be properly handled with respect to serializing of contents.- Overrides:
serializeWithType
in classJsonSerializer<java.util.Map<?,?>>
- Parameters:
value
- Value to serialize; can not be null.gen
- Generator used to output resulting Json contentprovider
- Provider that can be used to get serializers for serializing Objects value contains, if any.typeSer
