public static final LockType WRITE
Asynchronously flush changes to the Terracotta Server Array.


SYNCHRONOUS_WRITE

public static final LockType SYNCHRONOUS_WRITE
Synchronously flush changes to the Terracotta Server Array, blocking the calling method until data has been acknowledged as being committed.

Method Detail

values

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

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

valueOf

public static LockType 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:
