  Returns EnumArrayType<T>

Properties

optionalinheritedmeta

Inherited from ArrayType.platform

prop?: EntityProperty<any, any>

Inherited from ArrayType.prop

Accessors

inheritedname

• get name(): string

• Inherited from ArrayType.name

  Returns string

inheritedruntimeType

• get runtimeType(): string

• Inherited from ArrayType.runtimeType

  Returns string

Methods

inheritedcompareAsType

• compareAsType(): string

• Inherited from ArrayType.compareAsType

  How should the raw database values be compared? Used in EntityComparator. Possible values: string | number | bigint | boolean | date | any | buffer | array

  ---

  Returns string

optionalinheritedcompareValues

• compareValues(a: null | string, b: null | string): boolean

• Inherited from ArrayType.compareValues

  Allows to override the internal comparison logic.

  ---

  Parameters

  • a: null | string

  • b: null | string

  Returns boolean

convertToDatabaseValue

• convertToDatabaseValue(value: null | T[], platform: Platform, context?: TransformContext): null | string

• Overrides ArrayType.convertToDatabaseValue

  Converts a value from its JS representation to its database representation of this type.

  ---

  Parameters

  • value: null | T[]

  • platform: Platform

  • optionalcontext: TransformContext

  Returns null | string

optionalinheritedconvertToDatabaseValueSQL

• convertToDatabaseValueSQL(key: string, platform: Platform): string

• Inherited from ArrayType.convertToDatabaseValueSQL

  Converts a value from its JS representation to its database representation of this type.

  ---

  Parameters

  • key: string

  • platform: Platform

  Returns string

inheritedconvertToJSValue

• convertToJSValue(value: null | string | T[], platform: Platform): null | T[]

• Inherited from ArrayType.convertToJSValue

  Converts a value from its database representation to its JS representation of this type.

  ---

  Parameters

  • value: null | string | T[]

  • platform: Platform

  Returns null | T[]

optionalinheritedconvertToJSValueSQL

• convertToJSValueSQL(key: string, platform: Platform): string

• Inherited from ArrayType.convertToJSValueSQL

  Modifies the SQL expression (identifier, parameter) to convert to a JS value.

  ---

  Parameters

  • key: string

  • platform: Platform

  Returns string

inheritedensureComparable

• ensureComparable(meta: EntityMetadata<T>, prop: EntityProperty<T, any>): boolean

• Inherited from ArrayType.ensureComparable

  When a value is hydrated, we convert it back to the database value to ensure comparability, as often the raw database response is not the same as the convertToDatabaseValue result. This allows to disable the additional conversion in case you know it is not needed.

  ---

  Parameters

  • meta: EntityMetadata<T>

  • prop: EntityProperty<T, any>

  Returns boolean

getColumnType

• getColumnType(prop: EntityProperty<any, any>, platform: Platform): string

• Overrides ArrayType.getColumnType

  Gets the SQL declaration snippet for a field of this type.

  ---

  Parameters

  • prop: EntityProperty<any, any>

  • platform: Platform

  Returns string

optionalinheritedgetDefaultLength

• getDefaultLength(platform: Platform): number

• Inherited from ArrayType.getDefaultLength

  Get the default length for values of this type

  When doing schema generation, if neither "length" nor "columnType" option is provided, the length will be defaulted to this value.

  When doing entity generation, if the type is recognized to this type, and the inferred length is this value, the length option will be omitted in the output. If this method is not defined, length is always outputted based on what is in the database metadata.

  ---

  Parameters

  • platform: Platform

    The platform the default will be used for.

  Returns number

  The default value for the given platform.

inheritedtoJSON

• toJSON(value: T[]): T[]

• Inherited from ArrayType.toJSON

  Converts a value from its JS representation to its serialized JSON form of this type. By default uses the runtime value.

  ---

  Parameters

  • value: T[]

  Returns T[]

staticinheritedgetType

• getType(cls: TypeClass): InstanceType<TypeClass>

• Inherited from ArrayType.getType

  Parameters

  • cls: TypeClass

  Returns InstanceType<TypeClass>

staticinheritedisMappedType

• isMappedType(data: any): data is Type<any, any>

• Inherited from ArrayType.isMappedType

  Checks whether the argument is instance of Type.

  ---

  Parameters

  • data: any

  Returns data is Type<any, any>
