 public static enum IPreparedStatementCache.ReuseProbability extends java.lang.Enum<IPreparedStatementCache.ReuseProbability> An enum for the degree of probability to which a prepared statement is reused later on. This is used for managing the cache of prepared statements so that statements which are more likely reused are kept in the cache longer. Rule of thumb:- For global statements which are used regularly (such as lookup object in cdo_objects) use
 MAX.
- For constant object-specific statements which are used regularly use HIGH.
- For object-specific statements which are assembled from constants which are used regularly use
 MEDIUM.
- For all other dynamic statements, like queries, use LOW

Method Detail- 
valuespublic static IPreparedStatementCache.ReuseProbability[] 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 (IPreparedStatementCache.ReuseProbability c : IPreparedStatementCache.ReuseProbability.values()) System.out.println(c); - Returns:
- an array containing the constants of this enum type, in the order they are declared
 
 - 
valueOfpublic static IPreparedStatementCache.ReuseProbability 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:
- the enum constant with the specified name
- Throws:
- java.lang.IllegalArgumentException- if this enum type has no constant with the specified name
- java.lang.NullPointerException- if the argument is null
