Field Detail

DEFERRABLE

static final io.r2dbc.spi.Option<Boolean> DEFERRABLE

The DEFERRABLE transaction_mode is a PostgreSQL language extension.

Method Detail

from

static PostgresTransactionDefinition from(io.r2dbc.spi.IsolationLevel isolationLevel)

Creates a PostgresTransactionDefinition given IsolationLevel.

Parameters:

isolationLevel - the isolation level to use during the transaction.

Returns:

a new PostgresTransactionDefinition using IsolationLevel.

Throws:

IllegalArgumentException - if isolationLevel is null.

mutability

static PostgresTransactionDefinition mutability(boolean readWrite)

Creates a PostgresTransactionDefinition specifying transaction mutability.

Parameters:

readWrite - true for read-write transactions; false to use a read-only transaction.

Returns:

a new PostgresTransactionDefinition using the specified transaction mutability.

deferrable

PostgresTransactionDefinition deferrable()

Creates a PostgresTransactionDefinition retaining all configured options and using deferrable transaction semantics. Overrides transaction deferrability if configured already.

Returns:

a new PostgresTransactionDefinition retaining all configured options and using deferrable transaction semantics.

notDeferrable

PostgresTransactionDefinition notDeferrable()

Creates a PostgresTransactionDefinition retaining all configured options and using not deferrable transaction semantics. Overrides transaction deferrability if configured already.

Returns:

a new PostgresTransactionDefinition retaining all configured options and using not deferrable transaction semantics.

isolationLevel

PostgresTransactionDefinition isolationLevel(io.r2dbc.spi.IsolationLevel isolationLevel)

Creates a PostgresTransactionDefinition retaining all configured options and applying IsolationLevel.

Parameters:

isolationLevel - the isolation level to use during the transaction.

Returns:

a new PostgresTransactionDefinition retaining all configured options and applying IsolationLevel.

Throws:

IllegalArgumentException - if isolationLevel is null.

readOnly

PostgresTransactionDefinition readOnly()

Creates a PostgresTransactionDefinition retaining all configured options and using read-only transaction semantics. Overrides transaction muatbility if configured already.

Returns:

a new PostgresTransactionDefinition retaining all configured options and using read-only transaction semantics.

readWrite

PostgresTransactionDefinition readWrite()

Creates a PostgresTransactionDefinition retaining all configured options and using read-write transaction semantics. Overrides transaction mutability if configured already.

Returns:

a new PostgresTransactionDefinition retaining all configured options and using read-write transaction semantics.
