DynamicDomainCodec

internal class DynamicDomainCodec<T : Any>(val oid: Int, val pgTypeName: String, val pgSchema: String, baseTypeOid: Int, typeRegistry: TypeRegistry) : TypeCodec<T>

Codec for PostgreSQL domain types, which are essentially custom types based on underlying base types. It delegates serialization and deserialization to the codec of the base type.

Type Parameters

The Kotlin type of the underlying base type.

Constructors

DynamicDomainCodec

constructor(oid: Int, pgTypeName: String, pgSchema: String, baseTypeOid: Int, typeRegistry: TypeRegistry)

Properties

fromBinary

open override val fromBinary: (ByteArray, Int, Int) -> T

Function to deserialize a value from a PostgreSQL binary format.

isDefaultForKotlinType

open override val isDefaultForKotlinType: Boolean = false

Whether this codec is the default for its Kotlin type.

kotlinClass

open override val kotlinClass: KClass<T>

The Kotlin class this codec handles.

oid

open override val oid: Int

The OID of the domain type.

pgSchema

open override val pgSchema: String

The schema where the domain type is defined.

pgTypeName

open override val pgTypeName: String

The name of the domain type in PostgreSQL.

toBinary

open override val toBinary: (T, PgByteWriter) -> Unit

Function to serialize a value to a PostgreSQL binary format.

Functions

decodeSafely

internal fun <T : Any> TypeCodec<T>.decodeSafely(data: ByteArray, offset: Int, length: Int): T

Safely decodes a value using this TypeCodec. Any standard exceptions (like IllegalArgumentException or IllegalStateException) thrown by the codec's TypeCodec.fromBinary method are caught and wrapped in a CodecException.

encodeSafely

internal fun <T : Any> TypeCodec<T>.encodeSafely(value: T, writer: PgByteWriter)

Safely encodes a value using this TypeCodec. Any standard exceptions (like IllegalArgumentException or IllegalStateException) thrown by the codec's TypeCodec.toBinary method are caught and wrapped in a CodecException.
