Methods
compareAsType
How should the raw database values be compared? Used in
EntityComparator
. Possible values: string | number | bigint | boolean | date | any | buffer | arrayReturns string
optionalcompareValues
Allows to override the internal comparison logic.
Parameters
a: string
b: string
Returns boolean
convertToDatabaseValue
Converts a value from its JS representation to its database representation of this type.
Parameters
value: string | number
platform: Platform
optionalcontext: TransformContext
Returns string
optionalconvertToDatabaseValueSQL
Converts a value from its JS representation to its database representation of this type.
Parameters
key: string
platform: Platform
Returns string
convertToJSValue
Converts a value from its database representation to its JS representation of this type.
Parameters
value: string
Returns string | number
optionalconvertToJSValueSQL
Modifies the SQL expression (identifier, parameter) to convert to a JS value.
Parameters
key: string
platform: Platform
Returns string
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.Type parameters
- T: object
Parameters
meta: EntityMetadata<T>
prop: EntityProperty<T, any>
Returns boolean
getColumnType
Gets the SQL declaration snippet for a field of this type.
Parameters
prop: EntityProperty<any, any>
platform: Platform
Returns string
optionalgetDefaultLength
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.
toJSON
Converts a value from its JS representation to its serialized JSON form of this type. By default uses the runtime value.
Parameters
value: string | number
platform: Platform
Returns string | number
staticgetType
Type parameters
- JSType
- DBType = JSType
- TypeClass: Constructor<Type<JSType, DBType>> = Constructor<Type<JSType, DBType>>
Parameters
cls: TypeClass
Returns InstanceType<TypeClass>
staticisMappedType
Checks whether the argument is instance of
Type
.Parameters
data: any
Returns data is Type<any, any>
Type that maps an SQL DOUBLE to a JS string or number.
