Enum RequestKind

java.lang.Object

java.lang.Enum<RequestKind>

dagger.spi.model.RequestKind

All Implemented Interfaces:

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

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

Represents the different kinds of types that may be requested as dependencies for the same key. For example, String, Provider<String>, and Lazy<String> can all be requested if a key exists for String; they have the INSTANCE, PROVIDER, and LAZY request kinds, respectively.

Enum Constant Detail

INSTANCE

public static final RequestKind INSTANCE

A default request for an instance. E.g.: FooType

PROVIDER

public static final RequestKind PROVIDER

A request for a Provider. E.g.: Provider<FooType>

LAZY

public static final RequestKind LAZY

A request for a Lazy. E.g.: Lazy<FooType>

PROVIDER_OF_LAZY

public static final RequestKind PROVIDER_OF_LAZY

A request for a Provider of a Lazy. E.g.: Provider<Lazy<FooType>>

MEMBERS_INJECTION

public static final RequestKind MEMBERS_INJECTION

A request for a members injection. E.g. void injectMembers(FooType);. Can only be requested by component interfaces.

PRODUCER

public static final RequestKind PRODUCER

A request for a Producer. E.g.: Producer<FooType>

PRODUCED

public static final RequestKind PRODUCED

A request for a Produced. E.g.: Produced<FooType>

FUTURE

public static final RequestKind FUTURE

A request for a ListenableFuture. E.g.: ListenableFuture<FooType>. These can only be requested by component interfaces.

Method Detail

values

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

Returns:

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

valueOf

public static RequestKind 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

format

public java.lang.String format(Key key)

Returns a string that represents requests of this kind for a key.
