Interface OpenJPAEnum<E extends Enum<?>>

Type Parameters:
E - the enum type that needs to be converted.
All Known Implementing Classes:
FetchMode, IsolationLevel, LRSSizeAlgorithm, ResultSetType
public interface OpenJPAEnum<E extends Enum<?>>
An interface to define conversion of a facade based enum to a kernel integer constant. Facade specific enums implement this interface to convert user specified string or integer.

    Method
    Description
    int

    int
    toKernelConstant()
    Convert this receiver to an equivalent kernel constant.

  • Method Details

    • toKernelConstant

      int toKernelConstant()
      Convert this receiver to an equivalent kernel constant.

    • convertToKernelConstant

      int convertToKernelConstant(int i)
      Convert the given integer to an equivalent kernel constant. This method has a static semantics in the sense that it can be invoked on any enum instance, but the conversion is done w.r.t. all enums of the generic type.

    • convertToKernelConstant

      int convertToKernelConstant(String s)
      Convert the given String to an equivalent kernel constant. This method has a static semantics in the sense that it can be invoked on any enum instance, but the conversion is done w.r.t. all enums of the generic type.
