Enum CacheGetMode

java.lang.Object
  java.lang.Enum<CacheGetMode>
      javax.persistence.CacheGetMode

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<CacheGetMode>

public enum CacheGetMode
extends java.lang.Enum<CacheGetMode>

The javax.persistence.cacheGetMode property specifies the behavior when data is retrieved by the find methods and by the execution of queries. The cacheGetMode property is ignored for the refresh method, which always causes data to be retrieved from the database, not the cache.

Since:

Java Persistence 2.0

Method Detail

values

public static CacheGetMode[] values()

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

Returns:

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

valueOf

public static CacheGetMode valueOf(java.lang.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:
