Enum Constant Summary

Enum Constants

Enum Constant	Description
ArrayBaseOffset	The int or long field is set to the offset of the first array element of the array class RecomputeFieldValue.declClass(), as it would be computed by Unsafe.arrayBaseOffset(Class).
ArrayIndexScale	The int or long field is set to the element size array class RecomputeFieldValue.declClass(), as it would be computed by Unsafe.arrayIndexScale(Class).
ArrayIndexShift	The int or long field is set to the log2 of ArrayIndexScale.
AtomicFieldUpdaterOffset	Special support for field offsets used by java.util.concurrent.atomic.AtomicXxxFieldUpdater.
Custom	Use a FieldValueTransformer, which is specified as the target class.
FieldOffset	The int or long field is set to the offset of the field named Enum.name() of the class RecomputeFieldValue.declClass(), as it would be computed by Unsafe.objectFieldOffset(java.lang.reflect.Field).
FromAlias	The field is set to the value assigned to the Alias field.
Manual	Marker value that the field is intercepted by some manual logic.
NewInstance	The object field is set to a instance of RecomputeFieldValue.declClass() created by calling the default constructor.
NewInstanceWhenNotNull	The object field is set to a instance of RecomputeFieldValue.declClass() created by calling the default constructor when the target field value is not null.
None	The initial field value is not modified.
Reset	The field is reset to the default value (null, 0, false).
StaticFieldBase	The static field base Object as it would be computed by Unsafe.staticFieldBase(Field).
TranslateFieldOffset	The field offset stored in this int or long field is updated.

Method Summary

Enum Constant Details

None

public static final RecomputeFieldValue.Kind None

The initial field value is not modified. This is the default behavior when no RecomputeFieldValue annotation is present.

Since:

22.3

Reset

public static final RecomputeFieldValue.Kind Reset

The field is reset to the default value (null, 0, false).

Since:

22.3

NewInstance

public static final RecomputeFieldValue.Kind NewInstance

The object field is set to a instance of RecomputeFieldValue.declClass() created by calling the default constructor.

Since:

22.3

NewInstanceWhenNotNull

public static final RecomputeFieldValue.Kind NewInstanceWhenNotNull

The object field is set to a instance of RecomputeFieldValue.declClass() created by calling the default constructor when the target field value is not null.

Since:

22.3

FromAlias

public static final RecomputeFieldValue.Kind FromAlias

The field is set to the value assigned to the Alias field.

Since:

22.3

FieldOffset

public static final RecomputeFieldValue.Kind FieldOffset

The int or long field is set to the offset of the field named Enum.name() of the class RecomputeFieldValue.declClass(), as it would be computed by Unsafe.objectFieldOffset(java.lang.reflect.Field).

Since:

22.3

StaticFieldBase

public static final RecomputeFieldValue.Kind StaticFieldBase

The static field base Object as it would be computed by Unsafe.staticFieldBase(Field).

Since:

23.0

ArrayBaseOffset

public static final RecomputeFieldValue.Kind ArrayBaseOffset

The int or long field is set to the offset of the first array element of the array class RecomputeFieldValue.declClass(), as it would be computed by Unsafe.arrayBaseOffset(Class).

Since:

22.3

ArrayIndexScale

public static final RecomputeFieldValue.Kind ArrayIndexScale

The int or long field is set to the element size array class RecomputeFieldValue.declClass(), as it would be computed by Unsafe.arrayIndexScale(Class).

Since:

22.3

ArrayIndexShift

public static final RecomputeFieldValue.Kind ArrayIndexShift

The int or long field is set to the log2 of ArrayIndexScale.

Since:

22.3

AtomicFieldUpdaterOffset

public static final RecomputeFieldValue.Kind AtomicFieldUpdaterOffset

Special support for field offsets used by java.util.concurrent.atomic.AtomicXxxFieldUpdater.

Since:

22.3

TranslateFieldOffset

public static final RecomputeFieldValue.Kind TranslateFieldOffset

The field offset stored in this int or long field is updated. The original value must be a valid field offset in the hosted universe, and the new value is the field offset of the same field in the substrate universe. The field is looked up in the class RecomputeFieldValue.declClass().

Since:

22.3

Manual

public static final RecomputeFieldValue.Kind Manual

Marker value that the field is intercepted by some manual logic.

Since:

22.3

Custom

public static final RecomputeFieldValue.Kind Custom

Use a FieldValueTransformer, which is specified as the target class.

Since:

22.3

Method Details

values

public static RecomputeFieldValue.Kind[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static RecomputeFieldValue.Kind valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null
