Interface Result
- All Superinterfaces:
Closeable
- All Known Implementing Classes:
AbstractResult,MergedResult,ResultSetResult,SelectImpl.SelectResult
A result from the execution of a query or stored procedure. This
interface is aligned closely with the
ResultSet, so you
can expect like-named methods to have similar semantics. However, the
interface has been distilled and simplified, so a result object could
easily mask information sources other than a result set.
For more flexible customization of data loading, see the

Method Details
-
getEager
The eager result for the given key, or null if none. -
putEager
The eager result for the given key, or null if none. -
newJoins
Joins newJoins()Return a new joins instance to use for traversing to related data. -
close
void close()Free the resources used by this result; do not close the SQL connection. -
setLocking
void setLocking(boolean locking) Set to true if row locking has been issued for the row. -
isLocking
boolean isLocking()If true, then any results loaded from this Result will be locked in the database. -
supportsRandomAccess
Return true if the result supports random access.- Throws:
SQLException
-
absolute
