â–¸ Staticdecorate<T>(meta: EntityMetadata<T>, em: EntityManager<IDatabaseDriver<Connection>>): void
Type parameters:#
| Name | Type |
|---|---|
T | AnyEntity<T> |
Parameters:#
| Name | Type |
|---|---|
meta | EntityMetadata<T> |
em | EntityManager<IDatabaseDriver<Connection>> |
Returns: void

defineBaseProperties#
â–¸ Private StaticdefineBaseProperties<T>(meta: EntityMetadata<T>, prototype: T, em: EntityManager<IDatabaseDriver<Connection>>): void
Type parameters:#
| Name | Type |
|---|---|
T | AnyEntity<T> |
Parameters:#
| Name | Type |
|---|---|
meta | EntityMetadata<T> |
prototype | T |
em | EntityManager<IDatabaseDriver<Connection>> |
Returns: void
Defined in: packages/core/src/entity/EntityHelper.ts:55
defineIdProperty#
â–¸ Private StaticdefineIdProperty<T>(meta: EntityMetadata<T>, platform: Platform): void
defines magic id property getter/setter if PK property is _id and there is no id property defined
Type parameters:#
| Name | Type |
|---|---|
T | AnyEntity<T> |
Parameters:#
| Name | Type |
|---|---|
meta | EntityMetadata<T> |
platform | Platform |
Returns: void
Defined in: packages/core/src/entity/EntityHelper.ts:44
defineReferenceProperties#
â–¸ Private StaticdefineReferenceProperties<T>(meta: EntityMetadata<T>): void
Defines getter and setter for every owning side of m:1 and 1:1 relation. This is then used for propagation of
changes to the inverse side of bi-directional relations.
First defines a setter on the prototype, once called, actual get/set handlers are registered on the instance rather
than on its prototype. Thanks to this we still have those properties enumerable (e.g. part of Object.keys(entity)).
Type parameters:#
| Name | Type |
|---|---|
T | AnyEntity<T> |
Parameters:#
| Name | Type |
|---|---|
meta | EntityMetadata<T> |
Returns: void
Defined in: packages/core/src/entity/EntityHelper.ts:79

|---|---|
T | AnyEntity<T> |
Parameters:#
| Name | Type |
