Enum JPAVersion

java.lang.Object
java.lang.Enum<JPAVersion>
org.eclipse.persistence.jpa.jpql.JPAVersion
All Implemented Interfaces:
Serializable, Comparable<JPAVersion>
public enum JPAVersion extends Enum<JPAVersion>
An enumeration listing the various releases of the Java Persistence specification.

Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.

  • Enum Constant Details

    • DEFAULT_VERSION

      public static final JPAVersion DEFAULT_VERSION
      The constant for the default version used by the parsing system, which is always the latest version of the Java Persistence functional specification, which is version 2.0.

    • VERSION_1_0

      public static final JPAVersion VERSION_1_0
      The constant for the Java Persistence specification 1.0.

    • VERSION_2_0

      public static final JPAVersion VERSION_2_0
      The constant for the Java Persistence specification 2.0.

    • VERSION_2_1

      public static final JPAVersion VERSION_2_1
      The constant for the Java Persistence specification 2.1.

  • Method Details

    • values

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

    • valueOf

      public static JPAVersion 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

    • value

      public static JPAVersion value(String value)
      Retrieves the enumeration constant for the given value. If the value is not known, then DEFAULT_VERSION will be returned.
      Parameters:
      value - The value to retrieve its constant version
      Returns:
      The constant version of the given value

    • versions

      public static JPAVersion[] versions()
      Returns the list of JPAVersion excluding DEFAULT_VERSION.
      Returns:
      The list of unique constants

    • getVersion

      public String getVersion()
      Returns the real version this constant represents.
      Returns:
      The string value of the version

    • isNewerThan

      public boolean isNewerThan(JPAVersion version)
      Determines whether this constant represents a version that is newer than the given version.
      Parameters:
      version - The constant to verify if it's representing a version that is older than this one
      Returns:
      true if this constant represents a newer version and the given constant represents a version that is older; false if the given constant represents a newer and this constant represents an older version

    • isNewerThanOrEqual

      public boolean isNewerThanOrEqual(JPAVersion version)
      Determines whether this constant represents a version that is newer than the given version or if it's the same version.
      Parameters:
      version - The constant to verify if it's representing a version that is older than this one or if it's the same than this one
      Returns:
      true if this constant represents a newer version and the given constant represents a version that is older or if it's the same constant; false if the given constant represents a newer and this constant represents an older version

    • isOlderThan

      public boolean isOlderThan(JPAVersion version)
      Determines whether this constant represents a version that is older than the given version.
      Parameters:
      version - The constant to verify if it's representing a version that is more recent than this one
      Returns:
      true if this constant represents an earlier version and the given constant represents a version that is more recent; false if the given constant represents an earlier version and this constant represents a more recent version

    • isOlderThanOrEqual

      public boolean isOlderThanOrEqual(JPAVersion version)
      Determines whether this constant represents a version that is older than the given version or if it's the same version.
      Parameters:
      version - The constant to verify if it's representing a version that is more recent than this one or if it's the same than this one
      Returns:
      true if this constant represents an earlier version and the given constant represents a version that is more recent or if it's the same constant; false if the given constant represents an earlier version and this constant represents a more recent version

    • toCurrentVersion

      public JPAVersion toCurrentVersion()
      Converts the current constant to one of the known versions, this means if the constant is DEFAULT_VERSION, then it will be converted into the actual constant representing that version.
      Returns:
      Either this same constant or the actual version constant

    • toString

      public String toString()
      Overrides:
      toString in class Enum<JPAVersion>
