Enum Constant Detail

DEFAULT

public static final SLockMode DEFAULT

Acquire read locks for read operations and write locks for write operations.

public static final SLockMode READ_COMMITTED

Read committed isolation provides for cursor stability but not repeatable reads.

READ_UNCOMMITTED

public static final SLockMode READ_UNCOMMITTED

Read modified but not yet committed data.

RMW

Method Detail

values

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

Returns:

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

valueOf

public static SLockMode 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
