- java.lang.Object
- - java.lang.Enum<ReferenceType>
  - - org.codehaus.groovy.util.ReferenceType

- All Implemented Interfaces:
    Serializable, Comparable<ReferenceType>

      public enum ReferenceType
      extends Enum<ReferenceType>

- - ### Enum Constant Summary

    Enum Constants
    Enum Constant and Description
    `HARD`
    `PHANTOM`
    `SOFT`
    `WEAK`

  - ### Method Summary

    All Methods Static Methods Instance Methods Abstract Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `protected abstract <T,V extends Finalizable> Reference<T,V>` | `createReference(T value, V handler, ReferenceQueue queue)`
    `static ReferenceType` | `valueOf(String name)` Returns the enum constant of this type with the specified name.
    `static ReferenceType[]` | `values()` Returns an array containing the constants of this enum type, in the order they are declared.

    - #### SOFT

          public static final ReferenceType SOFT

    - #### WEAK

          public static final ReferenceType WEAK

    - #### PHANTOM

          public static final ReferenceType PHANTOM

    - #### HARD

          public static final ReferenceType HARD

  - ### Method Detail

    - #### values

          public static ReferenceType[] values()

      Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

          for (ReferenceType c : ReferenceType.values())
              System.out.println(c);

      Returns:
        an array containing the constants of this enum type, in the order they are declared

    - #### valueOf

          public static ReferenceType valueOf(String name)

      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name
        `NullPointerException` - if the argument is null

    - #### createReference

          protected abstract <T,V extends Finalizable> Reference<T,V> createReference(T value,
                                                                                      V handler,
                                                                                      ReferenceQueue queue)
