Interface ReactiveDataAccessStrategy

All Known Implementing Classes:

DefaultReactiveDataAccessStrategy

@Deprecated
public interface ReactiveDataAccessStrategy

Deprecated.

since 1.2 in favor of using direct usage of StatementMapper, UpdateMapper and R2dbcConverter.

Data access strategy that generalizes convenience operations using mapped entities. Typically used internally by R2dbcEntityOperations and repository support. SQL creation is limited to single-table operations and single-column primary keys.

Parameters:

entityType -

Returns:

all column names for a specific type.

getIdentifierColumns

List<SqlIdentifier> getIdentifierColumns(Class<?> entityType)

Deprecated.

Parameters:

entityType -

Returns:

all Id column names for a specific type.

getOutboundRow

OutboundRow getOutboundRow(Object object)

Deprecated.

Returns a OutboundRow that maps column names to a Parameter value.

Parameters:

object - must not be null.

Returns:

getBindValue

Parameter getBindValue(Parameter value)

Deprecated.

Return a potentially converted Parameter for strategies that support type conversion.

Parameters:

value - must not be null.

Returns:

Since:

1.2

getRowMapper

<T> BiFunction<Row, RowMetadata, T> getRowMapper(Class<T> typeToRead)

Deprecated.

Returns a row mapping function to map rows to T.

Type Parameters:

T -

Parameters:

typeToRead -

Returns:

toRowDocument

RowDocument toRowDocument(Class<?> type,
 Readable row,
 Iterable<? extends ReadableMetadata> metadata)

Deprecated.

Create a flat RowDocument from a single Row or Stored Procedure output.

Parameters:

type - the underlying entity type.

row - the row or stored procedure output to retrieve data from.

metadata - readable metadata.

Returns:

the RowDocument containing the data.

Since:

3.2

Parameters:

query - the query to expand.

parameterProvider - indexed parameter bindings.

Returns:

the PreparedOperation encapsulating expanded SQL and namedBindings.

Throws:

InvalidDataAccessApiUsageException - if a named parameter value cannot be resolved.
