java.lang.Object
java.lang.Enum<IDBPreparedStatement.ReuseProbability>
org.eclipse.net4j.db.IDBPreparedStatement.ReuseProbability
- All Implemented Interfaces:
- Serializable, Comparable<IDBPreparedStatement.ReuseProbability>
- Enclosing interface:
- IDBPreparedStatement
- public static enum IDBPreparedStatement.ReuseProbability
- extends Enum<IDBPreparedStatement.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 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
MAX
public static final IDBPreparedStatement.ReuseProbability MAX
HIGH
public static final IDBPreparedStatement.ReuseProbability HIGH
MEDIUM
public static final IDBPreparedStatement.ReuseProbability MEDIUM
LOW
public static final IDBPreparedStatement.ReuseProbability LOW
values
public static IDBPreparedStatement.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 (IDBPreparedStatement.ReuseProbability c : IDBPreparedStatement.ReuseProbability.values())
System.out.println(c);
- Returns:
- an array containing the constants of this enum type, in
the order they are declared
valueOf
public static IDBPreparedStatement.ReuseProbability 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
