References class

The most basic implementation of IReferences to store and locate component references.

See IReferences

Example

class MyController implements IReferenceable {
    IMyPersistence persistence;
    ...
    void setReferences(IReferences references) {
        persistence = references.getOneRequired<IMyPersistence>(
             Descriptor('mygroup', 'persistence', '*', '*', '1.0')
        );
    }
    ...
}

var persistence =  MyMongoDbPersistence();

var controller =  MyController();

var references = References.fromTuples([
     Descriptor('mygroup', 'persistence', 'mongodb', 'default', '1.0'), persistence,
     Descriptor('mygroup', 'controller', 'default', 'default', '1.0'), controller
]);
controller.setReferences(references);
Implemented types

Constructors

References([List tuples ])
Creates a new instance of references and initializes it with references. [...]

Properties

hashCode → int
The hash code for this object. [...]
read-only, inherited
runtimeType → Type
A representation of the runtime type of the object.
read-only, inherited

Methods

find<T>(dynamic locator, bool required) → List<T>
Gets all component references that match specified locator. [...]
override
getAll() → List
Gets all component references registered in this reference map. [...]
override
getAllLocators() → List
Gets locators for all registered component references in this reference map. [...]
override
getOneOptional<T>(dynamic locator) → T
Gets an optional component reference that matches specified locator. [...]
override
getOneRequired<T>(dynamic locator) → T
Gets a required component reference that matches specified locator. [...]
override
getOptional<T>(dynamic locator) → List<T>
Gets all component references that match specified locator. [...]
override
getRequired<T>(dynamic locator) → List<T>
Gets all component references that match specified locator. At least one component reference must be present. If it doesn't the method throws an error. [...]
override
put(dynamic locator dynamic component) → void
Puts a new reference into this reference map. [...]
override
remove(dynamic locator) → dynamic
Removes a previously added reference that matches specified locator. If many references match the locator, it removes only the first one. When all references shall be removed, use removeAll method instead. [...]
override
removeAll(dynamic locator) → List
Removes all component references that match the specified locator. [...]
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed. [...]
inherited
toString() → String
Returns a string representation of this object.
inherited

Operators

operator ==(dynamic other) → bool
The equality operator. [...]
inherited

Static Methods

fromTuples(List tuples) References
Creates a new References from a list of key-value pairs called tuples. [...]
