Enum TxIsolation

java.lang.Object
  extended by java.lang.Enum<TxIsolation>
      extended by com.avaje.ebean.TxIsolation
All Implemented Interfaces:
Serializable, Comparable<TxIsolation>

public enum TxIsolation
extends Enum<TxIsolation>

    

The Transaction Isolation levels.

These match those of java.sql.Connection with the addition of DEFAULT which implies the configured default of the DataSource.

This can be used with TxScope to define transactional scopes to execute method within.

Enum Constant Detail

READ_COMMITED

public static final TxIsolation READ_COMMITED
Read Committed Isolation level. This is typically the default for most configurations.


READ_UNCOMMITTED

public static final TxIsolation READ_UNCOMMITTED
Read uncommitted Isolation level.


REPEATABLE_READ

public static final TxIsolation REPEATABLE_READ
Repeatable Read Isolation level.


SERIALIZABLE

public static final TxIsolation SERIALIZABLE
Serializable Isolation level.


NONE

public static final TxIsolation NONE
No Isolation level.


DEFAULT

public static final TxIsolation DEFAULT
The default isolation level. This typically means the default that the DataSource is using or configured to use.

Method Detail

values

public static TxIsolation[] 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 (TxIsolation c : TxIsolation.values())
    System.out.println(c);

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

valueOf

public static TxIsolation 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

getLevel

public int getLevel()
Return the level as per java.sql.Connection.

Note that -1 denotes the default isolation level.


fromLevel

public static TxIsolation fromLevel(int connectionIsolationLevel)
Return the TxIsolation given the java.sql.Connection isolation level.

Note that -1 denotes the default isolation level.
