Enum Constant	Description
NO_CACHE	Hint that indicates that the operation should not perturb the Storage's cache, for example, when scanning over all records in a database.
READ_UNCOMMITTED	Hint that indicates that the caller can tolerate reads of uncommitted (or dirty) data.

Method Summary

Modifier and Type	Method	Description

Enum Constant Detail

NO_CACHE

public static final ReadableTransaction.ReadOption NO_CACHE

Hint that indicates that the operation should not perturb the Storage's cache, for example, when scanning over all records in a database. Note that there is no guarantee that this hint is effectively applied. The underlying transaction and/or storage implementation might not provide such cursor facility.

READ_UNCOMMITTED

public static final ReadableTransaction.ReadOption READ_UNCOMMITTED

Hint that indicates that the caller can tolerate reads of uncommitted (or dirty) data. The underlying storage may ignore this hint, or it may relax the cursor's isolation level if supported. Only use this hint when you really do not care about data being stable.

Method Detail

values

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

Returns:

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

valueOf

public static ReadableTransaction.ReadOption 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
