Annotation Type Binds

@Documented
 @Retention(value=RUNTIME)
 @Target(value=METHOD)
public @interface Binds

Annotates abstract methods of a Module that delegate bindings. For example, to bind Random to SecureRandom a module could declare the following: @Binds abstract Random bindRandom(SecureRandom secureRandom);

@Binds methods are a drop-in replacement for Provides methods that simply return an injected parameter. Prefer @Binds because the generated implementation is likely to be more efficient.

A @Binds method:

• Must be abstract.
• Must have a single parameter whose type is assignable to the return type. The return type is the bound type and the parameter is the type to which it is bound.
• May be scoped.
• May be qualified.
