PostgresArraySqlType<E extends Object> class final Getting Started

Postgres-native array codec for a column of element type E (e.g. integer[] → PostgresArraySqlType<int>, text[] → PostgresArraySqlType<String>).

package:postgres binds a Dart List<E> to the array parameter and returns the column as a List of E, so this codec is a typed pass-through: it forwards the list on encode and casts the driver's list to List<E> on decode. Null array elements are not supported (use a non-nullable E); wrap the whole codec in NullableSqlType for a nullable array column.

Emitted by the postgres adapter's native_types: true preset for the common array element types; a schema using it imports package:basalt_postgres.

Properties

decoder → Converter<Object?, List<E>>
Returns the decoder of this, converting from T to S.

encoder → Converter<List<E>, Object?>
Returns the encoder from S to T.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
inverted → Codec<Object?, List<E>>
Inverts this.
no setterinherited
postgresType → String?
Array type for the common element types; null for an element type this codec has no name for (such a column then can't be cast in updateAll).
no setteroverride
runtimeType → Type
A representation of the runtime type of the object.
