Introduction class final

An extra interface that a @DeclareParents field adds to the proxies of matching beans, with the way to create its implementation.

The generator writes one into the proxy factory of each bean that a @DeclareParents pattern matches. The generated proxy class implements interfaceName and forwards its members to the object create returns, one per proxy, created on first use. Applications never write it; they declare the @DeclareParents field.

// Generated for: @DeclareParents('*Service+',
//   defaultImpl: DefaultUsageTracked) static UsageTracked? mixin;
Introduction(
  interfaceName: 'UsageTracked',
  aspectType: 'UsageTracking',
  create: DefaultUsageTracked.new,
);

Spring (Java):

@DeclareParents(value = "com.x.service.*+",
    defaultImpl = DefaultUsageTracked.class)
public static UsageTracked mixin;

Constructors

Introduction({required String interfaceName, required String aspectType, required Object create()})

Describes the interface interfaceName introduced by the aspect named aspectType; create makes a new implementation.

Properties

aspectType → String

The aspect declaring it (its AspectMetadata.typeName). The bean is proxied for the introduction only while that aspect is registered in the context, so a condition or profile can turn it off.

final

hashCode → int

The hash code for this object.

no setter, inherited

interfaceName → String

The simple name of the introduced interface; this(Name) pointcuts match it.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

create() → Object

Creates a new object implementing the interface; the proxy calls it once, on first use.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

override

Operators

operator ==(Object other) → bool

The equality operator.
