Just like the title says, the reflect-metadata API comes with a method called getMetadata and another called getOwnMetadata. Can you explain the distinction between them? The same question applies to hasOwnMetadata, and so on.
Just like the title says, the reflect-metadata API comes with a method called getMetadata and another called getOwnMetadata. Can you explain the distinction between them? The same question applies to hasOwnMetadata, and so on.
Typically, the distinction between the `Own` versions and the regular ones lies in whether the search continues up the prototype chain. In the `Own` versions, only metadata specifically defined on the target object is retrieved. In the regular versions, if the metadata is not defined on the target object, metadata defined on the prototype of the object is returned.
For example:
@Reflect.metadata("key", "base value")
class B {
get prop(): number { return 0; }
}
class C extends B{ }
// "base value", metadata was not defined on C but was defined on its prototype B
console.log(Reflect.getMetadata("key", C));
// undefined, metadata was not defined on C
console.log(Reflect.getOwnMetadata("key", C));
