Annotation Interface SchemaProperty

@Retention(RUNTIME) @Inherited public @interface SchemaProperty
The SchemaProperty Object allows the definition of input and output data types nested within the properties attribute of a Schema annotation. These types can be objects, but also primitives and arrays. This object is an extended subset of the JSON Schema Specification Wright Draft 00.

      If a consumer is unaware of the meaning of the format, they shall fall back to using the basic type without format. For example, if \"type: integer, format: int128\" were used to designate a very large integer, most consumers will not understand how to handle it, and fall back to simply \"type: integer\"

    • readOnly

      boolean readOnly
      Relevant only for Schema "properties" definitions. Declares the property as "read only". This means that it MAY be sent as part of a response but SHOULD NOT be sent as part of the request.

      If the property is marked as readOnly being true and is in the required list, the required will take effect on the response only. A property MUST NOT be marked as both readOnly and writeOnly being true.

      Returns:
      whether or not this schema is read only
      Default:
      false

    • writeOnly

      Relevant only for Schema "properties" definitions. Declares the property as "write only". Therefore, it MAY be sent as part of a request but SHOULD NOT be sent as part of the response.

      If the property is marked as writeOnly being true and is in the required list, the required will take effect on the request only. A property MUST NOT be marked as both readOnly and writeOnly being true.

      Returns:
      whether or not this schema is write only
      Default:
      false

    • example

      String example
      A free-form property to include an example of an instance for this schema.

      To represent examples that cannot be naturally represented in JSON or YAML, a string value is used to contain the example with escaping where necessary.

      When associated with a specific media type, the example string shall be parsed by the consumer to be treated as an object or an array.
      Returns:
      an example of this schema
      Default:
      ""

    • externalDocs

      ExternalDocumentation externalDocs

      whether or not this schema is deprecated
      Default:

    • type

      SchemaType type
      Provides an override for the basic type of the schema.

      Value MUST be a string. Multiple types via an array are not supported.

      the type of this schema
      Default:
      DEFAULT

    • enumeration

      a list of allowed schema values
      Default:
      {}

    • defaultValue

      String defaultValue
      Provides a default value. The default value represents what would be assumed by the consumer of the input as the value of the schema if one is not provided.

      Unlike JSON Schema, the value MUST conform to the defined type for the Schema Object defined at the same level.

      For example, if type is string, then default can be "foo" but cannot be 1.
      Returns:
      the default value of this schema
      Default:
      ""

    • discriminatorProperty

      String discriminatorProperty
