Enum UseScope

java.lang.Object

java.lang.Enum<UseScope>

xsbti.UseScope

All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<UseScope>

public enum UseScope
extends java.lang.Enum<UseScope>

Defines the scope in which a name hash was captured. The incremental compiler uses [[UseScope]] to determine some Scala semantics assumed in the presence of a name in a concrete position. For instance, [[PatMatTarget]] is used for names that appear as the target types of a pattern match. The order of declaration of these is crucial. Don't change it. Don't add more than 6 scopes. Otherwise, change `Mapper` implementation.

Enum Constants

Enum Constant and Description
Default Represent standard definition/usage.
Implicit Used to track changes in implicit definition.
PatMatTarget Used in optimized sealed class invalidation (when IncOptions.seOptimizedSealed is true).

Enum Constant Detail

Default

public static final UseScope Default

Represent standard definition/usage. Default is present for each declaration and usage of given name.

Implicit

public static final UseScope Implicit

Used to track changes in implicit definition. So far classes don't depend on this scope since implicit changes has it's own invalidation process

PatMatTarget

public static final UseScope PatMatTarget

Used in optimized sealed class invalidation (when IncOptions.seOptimizedSealed is true). Only sealed classes/trait produce hash in this scope (for their names). Class have dependencies in PatMatTarget scope to all names used in type of pattern match target.

Method Detail

values

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

Returns:

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

valueOf

public static UseScope valueOf(java.lang.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:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null
