类 ResourceRegistryStandardImpl

java.lang.Object

org.hibernate.resource.jdbc.internal.ResourceRegistryStandardImpl

所有已实现的接口:

ResourceRegistry

public final class ResourceRegistryStandardImpl
extends Object
implements ResourceRegistry

Helps to track statements and resultsets which need being closed. This class is not threadsafe. Note regarding performance: we had evidence that allocating Iterators to implement the cleanup on each element recursively was the dominant resource cost, so we decided using "forEach" and lambdas in this case. However the forEach/lambda combination is able to dodge allocating Iterators on HashMap and ArrayList, but not on HashSet (at least on JDK8 and 11). Therefore some types which should ideally be modelled as a Set have been implemented using HashMap.

方法详细资料

hasRegisteredResources

public boolean hasRegisteredResources()

从接口复制的说明: ResourceRegistry

Does this registry currently have any registered resources?

指定者:

hasRegisteredResources 在接口中 ResourceRegistry

返回:

True if the registry does have registered resources; false otherwise.

register

public void register(Statement statement,
                     boolean cancelable)

从接口复制的说明: ResourceRegistry

Register a JDBC statement.

指定者:

register 在接口中 ResourceRegistry

参数:

statement - The statement to register.

cancelable - Is the statement being registered capable of being cancelled? In other words, should we register it to be the target of subsequent ResourceRegistry.cancelLastQuery() calls?

release

public void release(Statement statement)

从接口复制的说明: ResourceRegistry

Release a previously registered statement.

指定者:

release 在接口中 ResourceRegistry

参数:

statement - The statement to release.

release

public void release(ResultSet resultSet,
                    Statement statement)

从接口复制的说明: ResourceRegistry

Release a previously registered result set.

指定者:

release 在接口中 ResourceRegistry

参数:

resultSet - The result set to release.

statement - Statement from which ResultSet has been generated.

close

public static void close(Statement statement)

register

public void register(ResultSet resultSet,
                     Statement statement)

从接口复制的说明: ResourceRegistry

Register a JDBC result set.

Implementation note: Second parameter has been introduced to prevent multiple registrations of the same statement in case ResultSet.getStatement() does not return original Statement object.

指定者:

register 在接口中 ResourceRegistry

参数:

resultSet - The result set to register.

statement - Statement from which ResultSet has been generated.
