Enum Class PackStrategy

java.lang.Object

java.lang.Enum<PackStrategy>

org.codehaus.groovy.classgen.asm.PackStrategy

All Implemented Interfaces:

Serializable, Comparable<PackStrategy>, Constable

public enum PackStrategy
extends Enum<PackStrategy>

The compilation strategy the GEP-27 capability analysis selects for a closure literal: keep today's per-closure class, or pack the closure by hoisting its body to a method on the enclosing class behind a shared PackedClosure adapter. The GEP-27 lattice also foresees a metafactory strategy (functional-interface targets) and object elision, but those are separate, later work and are not represented here yet.

Method Details

values

public static PackStrategy[] 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 PackStrategy 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
