Use with @ExternalType.

  • Enum Constant Details

    • INT_128

      public static final ExternalPropertyType INT_128
      Representing type: ByteVector

      Encoding: 1:1 binary representation, little endian (16 bytes)

    • UUID

      public static final ExternalPropertyType UUID
      Representing type: ByteVector

      Encoding: 1:1 binary representation (16 bytes)

    • DECIMAL_128

      public static final ExternalPropertyType DECIMAL_128
      IEEE 754 decimal128 type, e.g. supported by MongoDB.

      Representing type: ByteVector

      Encoding: 1:1 binary representation (16 bytes)

    • FLEX_MAP

      public static final ExternalPropertyType FLEX_MAP
      A key/value map; e.g. corresponds to a JSON object or a MongoDB document (although not keeping the key order). Unlike the Flex type, this must contain a map value (e.g. not a vector or a scalar).

      Representing type: Flex

      Encoding: Flex

    • FLEX_VECTOR

      public static final ExternalPropertyType FLEX_VECTOR
      A vector (aka list or array) of flexible elements; e.g. corresponds to a JSON array or a MongoDB array. Unlike the Flex type, this must contain a vector value (e.g. not a map or a scalar).

      Representing type: Flex

      Encoding: Flex

    • JSON

      public static final ExternalPropertyType JSON
      Placeholder (not yet used) for a JSON document.

      Representing type: String

    • BSON

      public static final ExternalPropertyType BSON
      Placeholder (not yet used) for a BSON document.

      Representing type: ByteVector

    • JAVASCRIPT

      public static final ExternalPropertyType JAVASCRIPT
      JavaScript source code.

      Representing type: String

    • INT_128_VECTOR

      public static final ExternalPropertyType INT_128_VECTOR
      A vector (array) of Int128 values.

    • UUID_VECTOR

      public static final ExternalPropertyType UUID_VECTOR
      A vector (array) of Int128 values.

    • MONGO_ID

      public static final ExternalPropertyType MONGO_ID
      The 12-byte ObjectId type in MongoDB.

      Representing type: ByteVector

      Encoding: 1:1 binary representation (12 bytes)

    • MONGO_ID_VECTOR

      public static final ExternalPropertyType MONGO_ID_VECTOR
      A vector (array) of MongoId values.

    • MONGO_TIMESTAMP

      public static final ExternalPropertyType MONGO_TIMESTAMP
      Representing type: Long

      Encoding: Two unsigned 32-bit integers merged into a 64-bit integer.

    • MONGO_BINARY

      public static final ExternalPropertyType MONGO_BINARY
      Representing type: ByteVector

      Encoding: 3 zero bytes (reserved, functions as padding), fourth byte is the sub-type, followed by the binary data.

    • MONGO_REGEX

      public static final ExternalPropertyType MONGO_REGEX
      Representing type: string vector with 2 elements (index 0: pattern, index 1: options)

      Encoding: 1:1 string representation

  • Method Details

    • values

      public static ExternalPropertyType[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static ExternalPropertyType valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
