org.springframework.data.r2dbc.connectionfactory.ConnectionHolder

All Implemented Interfaces:

ResourceHolder

Deprecated.

since 1.2 in favor of Spring R2DBC. Use ConnectionHolder instead.

@Deprecated
public class ConnectionHolder
extends ResourceHolderSupport

Resource holder wrapping a R2DBC Connection. R2dbcTransactionManager binds instances of this class to the thread, for a specific ConnectionFactory.

Inherits rollback-only support for nested R2DBC transactions and reference count functionality from the base class.

Note: This is an SPI class, not intended to be used by applications.

Constructor Detail

ConnectionHolder

public ConnectionHolder(Connection connection)

Deprecated.

Create a new ConnectionHolder for the given R2DBC Connection, wrapping it with a SimpleConnectionHandle, assuming that there is no ongoing transaction.

Parameters:

connection - the R2DBC Connection to hold

See Also:

SimpleConnectionHandle, ConnectionHolder(Connection, boolean)

ConnectionHolder

public ConnectionHolder(Connection connection,
                        boolean transactionActive)

Deprecated.

Create a new ConnectionHolder for the given R2DBC Connection, wrapping it with a SimpleConnectionHandle.

Parameters:

connection - the R2DBC Connection to hold

transactionActive - whether the given Connection is involved in an ongoing transaction

See Also:

SimpleConnectionHandle

Method Detail

getConnectionHandle

@Nullable
public ConnectionHandle getConnectionHandle()

Deprecated.

Return the ConnectionHandle held by this ConnectionHolder.

hasConnection

protected boolean hasConnection()

Deprecated.

Return whether this holder currently has a Connection.

setTransactionActive

protected void setTransactionActive(boolean transactionActive)

Deprecated.

Set whether this holder represents an active, R2DBC-managed transaction.

See Also:

R2dbcTransactionManager

isTransactionActive

protected boolean isTransactionActive()

Deprecated.

Return whether this holder represents an active, R2DBC-managed transaction.

setConnection

protected void setConnection(@Nullable
                             Connection connection)

Deprecated.

Override the existing Connection handle with the given Connection. Reset the handle if given null.

Used for releasing the Connection on suspend (with a null argument) and setting a fresh Connection on resume.

getConnection

public Connection getConnection()

Deprecated.

Return the current Connection held by this ConnectionHolder.

This will be the same Connection until released gets called on the ConnectionHolder, which will reset the held Connection, fetching a new Connection on demand.

See Also:

ConnectionHandle.getConnection(), released()

released

public void released()

Deprecated.

Releases the current Connection held by this ConnectionHolder.

This is necessary for ConnectionHandles that expect "Connection borrowing", where each returned Connection is only temporarily leased and needs to be returned once the data operation is done, to make the Connection available for other operations within the same transaction.

Overrides:

released in class ResourceHolderSupport

clear

public void clear()

Deprecated.

Overrides:

clear in class ResourceHolderSupport
