Interface Field

All Superinterfaces:

Variable

public interface Field
extends Variable

Represents a field accessible by the body of a method. Note that the most commonly used features are inherited from the Variable interface.

Method Details

name

default Field name(String name)

Fields cannot be renamed, and so this method always throws an IllegalStateException.

Specified by:

name in interface Variable

Returns:

this variable

signature

default Field signature(Object... components)

Fields cannot have a signature defined within the body of a method, and so this method always throws an IllegalStateException.

Specified by:

signature in interface Variable

Returns:

this

set

Field set(Object value)

Assign a value to this variable, either from another variable or from a constant. A constant value can be a primitive type (boxed or unboxed), null, a String, a Class, an Enum, a MethodType, a MethodHandleInfo, a ConstantDesc, or a Constable.

Note that a MethodHandle can be set with a MethodHandleInfo, which is converted automatically at link time. Handling of ConstantDesc and Constable is also treated specially — the actual type is determined by the resolved constant.

Specified by:

set in interface Variable

value - a Variable or a constant

Returns:

this variable

varHandle

Variable varHandle()

Returns a VarHandle variable which accesses the field. If this is an ordinary field, the variable is actually a constant, and so it can be supplied as an argument to a bootstrap method or be used by another method in the same class. For non-static fields, the first VarHandle coordinate is the object instance which owns the field. Static fields have no coordinates.

methodHandleSet

Variable methodHandleSet()

Returns a MethodHandle variable for setting the field value. If this is an ordinary field, the variable is actually a constant, and so it can be supplied as an argument to a bootstrap method or be used by another method in the same class. For non-static fields, the MethodHandle accepts two arguments: the object instance which owns the field, and the value to set. For static fields, the only argument is the value to set.

methodHandleGet

Variable methodHandleGet()

Returns a MethodHandle variable for getting the field value. If this is an ordinary field, the variable is actually a constant, and so it can be supplied as an argument to a bootstrap method or be used by another method in the same class. For non-static fields, the MethodHandle accepts one argument: the object instance which owns the field. For static fields, there are no arguments.
