isEmpty
public boolean isEmpty(SerializerProvider prov, java.util.UUID 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.UUID>
-
serialize
public void serialize(java.util.UUID 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.UUID>
- 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
-
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 interfaceJsonFormatVisitable
- Overrides:
acceptJsonFormatVisitor
in classStdScalarSerializer<java.util.UUID>
typeHint
- Type of element (entity like property) being visited- Throws:
JsonMappingException
