All Implemented Interfaces:

Serializable, Comparable<ScrollMode>

public enum ScrollMode
extends Enum<ScrollMode>

Specifies the type of JDBC scrollable result set to use underneath a ScrollableResults.

Enum Constant Summary

Enum Constants

Enum Constant and Description
FORWARD_ONLY Requests a scrollable result that is only scrollable forwards.

SCROLL_SENSITIVE Requests a scrollable result which is sensitive to changes in the underlying data.

Method Summary

Modifier and Type	Method and Description
boolean	lessThan(ScrollMode other) Determine if this mode is "less than" the provided mode.
int	toResultSetType() Get the corresponding JDBC scroll type code constant value.
static ScrollMode	valueOf(String name) Returns the enum constant of this type with the specified name.

Enum Constant Detail

FORWARD_ONLY

public static final ScrollMode FORWARD_ONLY

Requests a scrollable result that is only scrollable forwards.

See Also:

ResultSet.TYPE_FORWARD_ONLY

SCROLL_SENSITIVE

public static final ScrollMode SCROLL_SENSITIVE

Requests a scrollable result which is sensitive to changes in the underlying data.

See Also:

ResultSet.TYPE_SCROLL_SENSITIVE

SCROLL_INSENSITIVE

public static final ScrollMode SCROLL_INSENSITIVE

Requests a scrollable result which is insensitive to changes in the underlying data.

Note that since the Hibernate session acts as a cache, you might need to explicitly evict objects, if you need to see changes made by other transactions.

See Also:

ResultSet.TYPE_SCROLL_INSENSITIVE

Method Detail

values

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

Returns:

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

valueOf

public static ScrollMode 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

toResultSetType

public int toResultSetType()

Get the corresponding JDBC scroll type code constant value.

Returns:

the JDBC result set type code

lessThan

public boolean lessThan(ScrollMode other)

Determine if this mode is "less than" the provided mode.

Parameters:

other - The provided mode

Returns:

true if this mode is less than the other.
