TypeManager

class TypeManager(registry: TypeRegistry, searchPathProvider: () -> List<String> = { emptyList() })

Manages the registration and resolution of PostgreSQL types, codecs, and converters.

This class provides a high-level API over TypeRegistry, making it easier to register custom mappings between Kotlin types and PostgreSQL database types.

Constructors

TypeManager

internal constructor(registry: TypeRegistry, searchPathProvider: () -> List<String> = { emptyList() })

Properties

codecDictionary

val codecDictionary: CodecDictionary

The dictionary maintaining TypeCodec implementations.

containers

val containers: ContainerFactory

Factory for creating container types (like composites).

converterRegistry

val converterRegistry: ConverterRegistry

The registry handling the conversion of parameters and results.

typeDictionary

val typeDictionary: TypeDictionary

The dictionary mapping PostgreSQL type names to their OIDs and vice versa.

Functions

registerAutoComposite

inline fun <T : Any> registerAutoComposite(typeName: String = "", schema: String = "")

Registers a composite type mapped reflectively onto the data class T.

fun registerAutoComposite(kClass: KClass<*>, typeName: String = "", schema: String = "")

Registers a composite type mapped reflectively onto the data class kClass.

registerCodec

fun registerCodec(codec: TypeCodec<*>)

Registers a custom TypeCodec for encoding and decoding database types at the lowest level.

registerEnum

inline fun <T : Enum<T>> registerEnum(typeName: String = "", schema: String = "", pgConvention: CaseConvention = CaseConvention.SNAKE_CASE_UPPER, kotlinConvention: CaseConvention = CaseConvention.PASCAL_CASE)

fun registerEnum(enumClass: KClass<*>, typeName: String = "", schema: String = "", pgConvention: CaseConvention = CaseConvention.SNAKE_CASE_UPPER, kotlinConvention: CaseConvention = CaseConvention.PASCAL_CASE)

Registers an enum type, creating both parameter and result converters.

registerParameterConverter

fun registerParameterConverter(converter: ParameterConverter<*>)

Registers a custom ParameterConverter for mapping Kotlin types to PostgreSQL database types.

registerResultConverter

fun registerResultConverter(converter: ResultConverter<*, *>)

Registers a custom ResultConverter for mapping PostgreSQL database types to Kotlin types.

resolveOid

fun resolveOid(typeName: String, schema: String = "", isArray: Boolean = false): Int

Resolves an OID for a given type name, considering the current search path.
