Package org.springframework.data.r2dbc.core

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.

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:

1.2

getRowMapper

<T>
BiFunction<io.r2dbc.spi.Row,io.r2dbc.spi.RowMetadata,T> getRowMapper(Class<T> typeToRead)

Deprecated.

Returns a row mapping function to map rows to T.

Type Parameters:

T -

Parameters:

typeToRead -

Returns:

getTableName

SqlIdentifier getTableName(Class<?> type)

Deprecated.

Parameters:

type -

Returns:

the table name for the entity type.

processNamedParameters

@Deprecated
PreparedOperation<?> processNamedParameters(String query,
 ReactiveDataAccessStrategy.NamedParameterProvider parameterProvider)

Deprecated.

since 1.2. DatabaseClient encapsulates named parameter handling entirely.

Expand named parameters and return a PreparedOperation wrapping the given bindings.

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.

getStatementMapper

StatementMapper getStatementMapper()

Deprecated.

Returns the R2dbcDialect-specific StatementMapper.

Returns:

the R2dbcDialect-specific StatementMapper.

getConverter

R2dbcConverter getConverter()

Deprecated.

Returns the R2dbcConverter.

Returns:

the R2dbcConverter.

toSql

String toSql(SqlIdentifier identifier)

Deprecated.

Render a SqlIdentifier for SQL usage.

Parameters:

identifier - the identifier to be rendered.

Returns:

the SQL representation of the identifier with applied, potentially dialect-specific, processing rules.

Since:

1.1

• SqlIdentifier.toSql(IdentifierProcessing)

renderForGeneratedValues

default String renderForGeneratedValues(SqlIdentifier identifier)

Deprecated.

Render a SqlIdentifier in a way suitable for registering it as a generated key with a statement through Statement#returnGeneratedValues.

Parameters:

identifier - to render. Must not be null.

Returns:

rendered identifier. Guaranteed to be not null.
