API

Type Map

Either Reflector or Metadata Setter accepts 2 type arguments. The first one is the type map of common types, while the second one is the type map of arrays.

Reflector

• Reflector.get(metadataKey, instance, key) Fetches the metadata of instance.

• Reflector.getArray(metadataKey, instance, key) Fetches the array metadata of instance. Will return empty array if not exists.

• Reflector.getProperty(metadataKey, instance, key, alternate = instance) Fetches the array metadata of instance from both class and property. The last parameter is an alternate source object for fetching metadata from class.

Metadata Setter

• MetadataSetter.set(metadataKey, value) Sets and overrides the MetadataSetter.

• MetadataSetter.append(metadataKey, value) Append to the the metadata array. The array would be created if not exists.

• MetadataSetter.appendUnique(metadataKey, value) Same as above but no duplicate values.

• MetadataSetter.concat(metadataKey, value) The value must be an array, and the metadata array would be joined together.
