Method Details

scanResultSet

public <R> R scanResultSet(ResultSetScanner<R> resultSetScanner)

Description copied from interface: ResultBearing

Invokes the mapper with a result set supplier, and returns the value returned by the mapper.

Specified by:

scanResultSet in interface ResultBearing

Type Parameters:

R - result type returned by the mapper.

Parameters:

resultSetScanner - result set scanner

Returns:

the value returned by the mapper.

execute

public <R> R execute()

getHandle

public final Handle getHandle()

getConfig

public ConfigRegistry getConfig()

Description copied from interface: Configurable

Returns the configuration registry associated with this object.

Specified by:

getConfig in interface Configurable<This>

Returns:

the configuration registry associated with this object.

getContext

public final StatementContext getContext()

Returns the statement context associated with this statement.

Returns:

the statement context associated with this statement.

attachToHandleForCleanup

@Beta
public final MetaData attachToHandleForCleanup()

Registers with the handle for cleaning when the handle is closed.
There are some situations where Statements need to be cleaned up to avoid resource leaks. This method registers the current Statement it with the Handle. If the statement or the context are cleaned by themselves, it will automatically unregister, so in normal operations, resources should not pool for cleanup with the Handle.
