Constructors

constructor

new BaseBind(): BaseBind
Creates an instance of the MetaObject class.

Returns BaseBind
Inherited from MetaObject.constructor
- Defined in node_modules/logic-core/types/en/meta-object.d.ts:12

Properties

_baseTable

_baseTable: MetaTable

Defines the default entity. This entity represents a meta table.

_guid

_guid: string

Unique identifier of the object (GUID). Uniquely identifies the object.

_type

_type: Function

The generator function of the object. The function used when the object was created.

$event

$event: EventEmitter

Event object. Processes the issuance and reception of events.

$KEYWORD

$KEYWORD: string[]

This is the collection reservation word. Defines the reserved words that you use by default.

`Static` `Readonly`_NS

_NS: string

Indicates the namespace.

Default

'Meta'

`Static` `Readonly`_PARAM

_PARAM: []

List of parameters used for the constructor.

`Static` `Readonly`_UNION

_UNION: []

List of implemented interfaces.

Default

[IObject, IMarshal]

Methods

_onExecute

_onExecute(cmd): void
Event listener before command execution.
Parameters
- cmd: BaseBindCommand
  command object to be executed.
Returns void
Listens
BaseBind#onExecute
- Defined in types/en/base-bind.d.ts:54

_onExecuted

_onExecuted(cmd, result): void
Event listener after command execution.
Parameters
- cmd: BaseBindCommand
  Command object executed.
- result: object
  The result object of the command execution.
Returns void
Listens
BaseBind#onExecuted
- Defined in types/en/base-bind.d.ts:63

`Abstract`addColumn

addColumn(...args): void
Adds a column to the meta table.
Parameters
- Rest...args: any[]
  properties of the column to be added.
Returns void
- Defined in types/en/base-bind.d.ts:95

equal

equal(target): boolean
Compare the current object with the specified object.
Parameters
- target: object
  the object to be compared to.
Returns boolean
Returns whether the two objects are the same.
Inherited from MetaObject.equal
- Defined in node_modules/logic-core/types/en/meta-object.d.ts:30

getObject

getObject(vOpt?, owned?): object
Method of obtaining the current object as a guide type object. (Circular references are replaced by $ref values.)
Parameters
- OptionalvOpt: number
  Import option.
  - opt=0: Reference structure (_guid: Yes, $ref: Yes)
  - opt=1: Redundant structure (_guid: Yes, $ref: Yes)
  - opt=2: Non-steep structure (_guid: No, $ref: No)
- Optionalowned: object | object[]
Returns object
Example
```
a.getObject(2) == b.getObject(2)
```
Overrides MetaObject.getObject
- Defined in types/en/base-bind.d.ts:78

getTypes

getTypes(): Function[]
Returns the creators of the current object and all the creators of the prototype chain to the array.

Returns Function[]
Returns the array of generator functions.
Example
```
const types = obj.getTypes();
console.log(types); // [Function: MetaObject]
```
Inherited from MetaObject.getTypes
- Defined in node_modules/logic-core/types/en/meta-object.d.ts:41

instanceOf

instanceOf(target): boolean
Verify that the current object is an instance of the specified type (including _UNION)
Parameters
- target: string | object
  The type of object to be checked (object or string).
Returns boolean
Returns whether it is an instance of the specified type.
Inherited from MetaObject.instanceOf
- Defined in node_modules/logic-core/types/en/meta-object.d.ts:49

setObject

setObject(oGuid, origin?): void
Sets the Guid type object to the current object. (The object is reset.)
Parameters
- oGuid: object
  Object of the guid type to serialize.
- Optionalorigin: object
  The source object setting the current object.
Returns void
Overrides MetaObject.setObject
- Defined in types/en/base-bind.d.ts:87

Events

onExecute

onExecute: ((cmd: BaseBindCommand) => void)

An event that is called before the command is executed.

Type declaration

- (cmd): void
- Parameters
  - cmd: BaseBindCommand
    command object to be executed.
  Returns void

onExecuted

onExecuted: ((cmd: BaseBindCommand, result: object) => void)

An event that is called after the command is executed.

Type declaration

- (cmd, result): void
- Parameters
  - cmd: BaseBindCommand
    Command object executed.
  - result: object
    The result object of the command execution.
  Returns void
