## Class UUIDSerializer

- java.lang.Object
- - com.fasterxml.jackson.databind.JsonSerializer<T>
  - - com.fasterxml.jackson.databind.ser.std.StdSerializer<T>
    - - com.fasterxml.jackson.databind.ser.std.StdScalarSerializer<java.util.UUID>

- All Implemented Interfaces:
    JsonFormatVisitable, SchemaAware, java.io.Serializable

      public class UUIDSerializer
      extends StdScalarSerializer<java.util.UUID>

  Specialized `JsonSerializer` to output `UUID`s. Beyond optimized access and writing of textual representation (which is the default handling in most cases), it will alternatively allow serialization using raw binary output (as 16-byte block) if underlying data format has efficient means to access that.

    Methods
    Modifier and Type | Method and Description
    --- | ---
    `boolean` | `isEmpty(SerializerProvider prov, java.util.UUID value)` Method called to check whether given serializable value is considered "empty" value (for purposes of suppressing serialization of empty values).
    `void` | `serialize(java.util.UUID value, com.fasterxml.jackson.core.JsonGenerator gen, SerializerProvider provider)` Method that can be called to ask implementation to serialize values of type this serializer handles.

          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 class `JsonSerializer<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 class `StdSerializer<java.util.UUID>`
      Parameters:
        `value` - Value to serialize; can not be null.
        `gen` - Generator used to output resulting Json content
        `provider` - Provider that can be used to get serializers for serializing Objects value contains, if any.
      Throws:
        `java.io.IOException`
