Enum Constant Details

STATIC

public static final FieldAccess STATIC

The representation of field access to a static field.

INSTANCE

public static final FieldAccess INSTANCE

The representation of field access to an instance field.

Field Details

putterOpcode

private final int putterOpcode

The opcode for setting a field value.

getterOpcode

private final int getterOpcode

The opcode for getting a field value.

targetSizeChange

private final int targetSizeChange

The amount of operand slots this field access operation consumes when it is applied before eventually adding new values onto the operand stack.

Constructor Details

FieldAccess

private FieldAccess(int putterOpcode,
 int getterOpcode,
 StackSize targetSizeChange)

Creates a new field access.

Parameters:

putterOpcode - The opcode for setting a field value.

getterOpcode - The opcode for getting a field value.

targetSizeChange - The amount of operand slots this field access operation consumes when it is applied before eventually adding new values onto the operand stack.

Method Details

values

public static FieldAccess[] 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 FieldAccess 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

forEnumeration

public static StackManipulation forEnumeration(EnumerationDescription enumerationDescription)

Creates an accessor to read an enumeration value.

Parameters:

enumerationDescription - The description of the enumeration.

Returns:

A stack manipulation for reading the enumeration.

forField

public static FieldAccess.Defined forField(FieldDescription.InDefinedShape fieldDescription)

Creates a field access representation for a given field.

Parameters:

fieldDescription - The field to be accessed.

Returns:

A field access definition for the given field.

forField

public static FieldAccess.Defined forField(FieldDescription fieldDescription)

Creates a field access representation for a given field. If the field's return type derives from its declared shape, the value is additionally casted to the generically resolved field.

Parameters:

fieldDescription - The field to be accessed.

Returns:

A field access definition for the given field.
