Interface Summary

Modifier and Type	Interface and Description
pack-priv interface	BindParameterSource Interface that defines common functionality for objects that can offer parameter values for named bind parameters, serving as argument for `NamedParameterExpander` operations.
public interface	ConnectionAccessor Interface declaring methods that accept callback `Function` to operate within the scope of a `Connection`.
pack-priv interface	ConnectionFunction< the type of the result of the function. R> Union type combining `Function` and `SqlProvider` to expose the SQL that is related to the underlying action.
public interface	DatabaseClient A non-blocking, reactive client for performing database calls with Reactive Streams back pressure.
public interface	ExecuteFunction Represents a function that executes a `Statement` for a (delayed) `Result` stream.
public interface	FetchSpec< the row result type T> Union type for fetching results.
public interface	PreparedOperation< underlying operation source T> Extension to `QueryOperation` for a prepared SQL query `Supplier` with bound parameters.
public interface	QueryOperation Interface declaring a query operation that can be represented with a query string.
public interface	RowsFetchSpec< the row result type T> Contract for fetching tabular results.
public interface	SqlProvider Interface to be implemented by objects that can provide SQL strings.
public interface	StatementFilterFunction Represents a function that filters an `ExecuteFunction`.
public interface	UpdatedRowsFetchSpec Contract for fetching the number of affected rows.

Class Summary

Modifier and Type	Class and Description
public class	BeanPropertyRowMapper< the result type T> Mapping `Function` implementation that converts an R2DBC `Readable` (a `Row` or `OutParameters`) into a new instance of the specified mapped target class.
public class	ColumnMapRowMapper `Mapping function` implementation that creates a `java.util.Map` for each row, representing all columns as key-value pairs: one entry for each column, with the column name as key.
public class	DataClassRowMapper< the result type T> Mapping `Function` implementation that converts an R2DBC `Readable` (a `Row` or `OutParameters`) into a new instance of the specified mapped target class.
pack-priv class	DefaultDatabaseClient The default implementation of `DatabaseClient`, as created by the static factory method.
pack-priv class	DefaultDatabaseClientBuilder Default implementation of `DatabaseClient.Builder`.
pack-priv class	DefaultFetchSpec< the row result type T> Default `FetchSpec` implementation.
pack-priv class	DelegateConnectionFunction< the type of the result of the function. R> A `ConnectionFunction` that delegates to a `SqlProvider` and a plain `Function`.
pack-priv class	MapBindParameterSource `BindParameterSource` implementation that holds a given `Map` of parameters encapsulated as `Parameter`.
pack-priv class	NamedParameterExpander SQL translation support allowing the use of named parameters rather than native placeholders.
pack-priv abstract class	NamedParameterUtils Helper methods for named parameter parsing.
public class	Parameter Deprecated since 6.0. since 6.0, use `io.r2dbc.spi.Parameter` instead. A database value that can be set in a statement.
pack-priv class	ParsedSql Holds information about a parsed SQL statement.
pack-priv class	ResultFunction A `ConnectionFunction` that produces a `Flux` of `Result` and that defers generation of the SQL until the function has been applied.
