Convenience field to make the injection look more readable when used with default values for the injection.
Convenience field to make the injection look more readable when used with default values for the injection.
Example:
inject [Database] (by default defaultDb)
Implicit cast of classes that can be identifiers to an InjectConstraints with the identified as a first element.
Implicit cast of classes that can be identifiers to an InjectConstraints with the identified as a first element.
Often used when a list of identifiers should be passed (for example for inject(constraint) method).
This lets us to put the identifier in a first place to make the parameters look readable.
type that qualifies as an identifier
Instance of a class that qualifies as an identifier
InjectConstraints
Convenience field to make the injection look more readable when used with identifiers.
Convenience field to make the injection look more readable when used with identifiers.
Example:
inject [Database] (identified by 'local)
Injects a dependency defined by a constraint.
Injects a dependency defined by a constraint.
Usually used when there are more than one injections for a defined type T
Example:
binding identifiedBy 'host to "hostName" val host = inject[String]('host) // equals to "hostName" val db = inject (by default defaultDb) // notice that type `T` is optional in inferred in this case

implicit Injector, should be defined in the scope. It's used to lookup bindings
ensures that meta-information if type T is available at the runtime
ensures, that type T is not inferred as Nothing by scala compiler,
since inject needs to know the actual type at the runtime

Injects a dependency that was previously defined in a module
Injects a dependency that was previously defined in a module
Example:
val database = inject [Database] // database can now be used as an instance of Database class

a new instance of injected dependency
Injects a dependency defined by type T.
Injects a dependency defined by type T. If dependency is not found, initializes it with the default
value from the constructor of type T.
This implies, that constructor must have one constructor with parameter paramName which has
a default value. Method is part of injected macro implementation and not intended to be used outside of it.
Uses reflection.
