Enum DependencyType

java.lang.Object

java.lang.Enum<DependencyType>

com.android.build.gradle.shrinker.DependencyType

All Implemented Interfaces:

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

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

Type of the dependency (edge) between two nodes in the shrinker graph.

A node is considered "reachable" if:

• it can be reached with a required edge, or
• at least one IF_CLASS_KEPT and at least one CLASS_IS_KEPT edge, or
• at least one SUPERINTERFACE_KEPT and at least one INTERFACE_IMPLEMENTED edge.

The second case models the situation where a method implements an interface method. The only case when it should be kept is if the interface method is called somewhere (1) AND the containing class is used in some way (2). Otherwise the super-method can be removed from both the interface and the class (not 1) or the whole implementation class can be removed (not 2).

Enum Constant Summary

Enum Constants

Enum Constant and Description
CLASS_IS_KEPT Target member's owner class is kept.
IF_CLASS_KEPT Target member should be kept, assuming its owner class is kept.
INTERFACE_IMPLEMENTED Target interface is implemented (directly or indirectly) by a kept class, so it may need to be kept if a superinterface is kept as well.
REQUIRED_CLASS_STRUCTURE Target type is referenced in class declaration.
REQUIRED_CODE_REFERENCE Target is referenced from an opcode.
REQUIRED_CODE_REFERENCE_REFLECTION Target is referenced by name in reflection code.
REQUIRED_KEEP_RULES Target is kept by keep rules.
SUPERINTERFACE_KEPT Superinterface of the target interface is kept.

Modifier and Type	Method and Description
static DependencyType	valueOf(java.lang.String name) Returns the enum constant of this type with the specified name.
static DependencyType[]	values() Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

REQUIRED_CODE_REFERENCE

public static final DependencyType REQUIRED_CODE_REFERENCE

Target is referenced from an opcode.

REQUIRED_CODE_REFERENCE_REFLECTION

public static final DependencyType REQUIRED_CODE_REFERENCE_REFLECTION

Target is referenced by name in reflection code. Same as above, but doesn't trigger warnings.

REQUIRED_CLASS_STRUCTURE

public static final DependencyType REQUIRED_CLASS_STRUCTURE

Target type is referenced in class declaration.

REQUIRED_KEEP_RULES

public static final DependencyType REQUIRED_KEEP_RULES

Target is kept by keep rules.

IF_CLASS_KEPT

public static final DependencyType IF_CLASS_KEPT

Target member should be kept, assuming its owner class is kept.

See Also:

CLASS_IS_KEPT

CLASS_IS_KEPT

public static final DependencyType CLASS_IS_KEPT

Target member's owner class is kept.

See Also:

IF_CLASS_KEPT

SUPERINTERFACE_KEPT

public static final DependencyType SUPERINTERFACE_KEPT

Superinterface of the target interface is kept. If the target is implemented by some class, it should be kept as well.

See Also:

INTERFACE_IMPLEMENTED

INTERFACE_IMPLEMENTED

public static final DependencyType INTERFACE_IMPLEMENTED

Target interface is implemented (directly or indirectly) by a kept class, so it may need to be kept if a superinterface is kept as well.

See Also:

SUPERINTERFACE_KEPT

Method Detail

values

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

Returns:

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

valueOf

public static DependencyType 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
