Class PropertySerializerMap

java.lang.Object

com.fasterxml.jackson.databind.ser.impl.PropertySerializerMap

public abstract class PropertySerializerMap
extends Object

Helper container used for resolving serializers for dynamic (possibly but not necessarily polymorphic) properties: properties whose type is not forced to use dynamic (declared) type and that are not final. If so, serializer to use can only be established once actual value type is known. Since this happens a lot unless static typing is forced (or types are final) this implementation is optimized for efficiency. Instances are immutable; new instances are created with factory methods: this is important to ensure correct multi-threaded access.

Modifier and Type	Field and Description
protected boolean	_resetWhenFull Configuration setting that determines what happens when maximum size (currently 8) is reached: if true, will "start from beginning"; if false, will simply stop adding new entries.

Method Summary

Modifier and Type	Method and Description
PropertySerializerMap.SerializerAndMapResult	addSerializer(Class<?> type, JsonSerializer<Object> serializer) Method that can be used to 'register' a serializer that caller has resolved without help of this map.
PropertySerializerMap.SerializerAndMapResult	addSerializer(JavaType type, JsonSerializer<Object> serializer)
static PropertySerializerMap	emptyForProperties()
static PropertySerializerMap	emptyForRootValues()
PropertySerializerMap.SerializerAndMapResult	findAndAddKeySerializer(Class<?> type, SerializerProvider provider, BeanProperty property) Method called if initial lookup fails, when looking for a key serializer (possible attached indirectly to a property) Will both find serializer and construct new map instance if warranted, and return both.
PropertySerializerMap.SerializerAndMapResult	findAndAddPrimarySerializer(Class<?> type, SerializerProvider provider, BeanProperty property) Method called if initial lookup fails, when looking for a primary serializer (one that is directly attached to a property).
PropertySerializerMap.SerializerAndMapResult	findAndAddPrimarySerializer(JavaType type, SerializerProvider provider, BeanProperty property)
PropertySerializerMap.SerializerAndMapResult	findAndAddRootValueSerializer(Class<?> type, SerializerProvider provider) Method called if initial lookup fails, when looking for a root value serializer: one that is not directly attached to a property, but needs to have TypeSerializer wrapped around it.

PropertySerializerMap.SerializerAndMapResult	findAndAddSecondarySerializer(Class<?> type, SerializerProvider provider, BeanProperty property) Method called if initial lookup fails, when looking for a non-primary serializer (one that is not directly attached to a property).

Method Detail

serializerFor

public abstract JsonSerializer<Object> serializerFor(Class<?> type)

Main lookup method. Takes a "raw" type since usage is always from place where parameterization is fixed such that there cannot be type-parametric variations.
