| Cursor | | Cursor(Database dbHandle, Transaction txn, CursorConfig cursorConfig) throws DatabaseException(Code) | | Creates a cursor for a given user transaction.
If txn is null, a non-transactional cursor will be created that
releases locks for the prior operation when the next operation
suceeds.
|
| Cursor | | Cursor(Database dbHandle, Locker locker, CursorConfig cursorConfig) throws DatabaseException(Code) | | Creates a cursor for a given locker.
If locker is null or is non-transactional, a non-transactional cursor
will be created that releases locks for the prior operation when the
next operation suceeds.
|
| Cursor | | Cursor(DatabaseImpl dbImpl, Locker locker, CursorConfig cursorConfig) throws DatabaseException(Code) | | Creates a cursor for a given locker and no db handle.
The locker parameter must be non-null. With this constructor, we use
the given locker without applying any special rules for different
isolation levels -- the caller must supply the correct locker.
|
| checkState | | void checkState(boolean mustBeInitialized) throws DatabaseException(Code) | | Check the environment and cursor state.
|
| close | | public void close() throws DatabaseException(Code) | | Javadoc for this public method is generated via
the doc templates in the doc_src directory.
|
| close | | synchronized void close(boolean releaseNonTxnLocks) throws DatabaseException(Code) | |
Parameters:
releaseNonTxnLocks - should normally be true. SeeCursorImpl.close(boolean) [#15573] |
| count | | public int count() throws DatabaseException(Code) | | Javadoc for this public method is generated via
the doc templates in the doc_src directory.
|
| deleteInternal | | OperationStatus deleteInternal() throws DatabaseException(Code) | | Internal version of delete() that does no parameter checking. Calls
deleteNoNotify() and notifies triggers (performs secondary updates).
|
| deleteNoNotify | | OperationStatus deleteNoNotify() throws DatabaseException(Code) | | Clone the cursor, delete at current position, and if successful, swap
cursors. Does not notify triggers (does not perform secondary updates).
|
| dup | | public Cursor dup(boolean samePosition) throws DatabaseException(Code) | | Javadoc for this public method is generated via
the doc templates in the doc_src directory.
|
| getConfig | | public CursorConfig getConfig()(Code) | | Javadoc for this public method is generated via
the doc templates in the doc_src directory.
|
| getDatabase | | public Database getDatabase()(Code) | | Javadoc for this public method is generated via
the doc templates in the doc_src directory.
|
| getDatabaseImpl | | DatabaseImpl getDatabaseImpl()(Code) | | Always returns non-null, while getDatabase() returns null if no handle
is associated with this cursor.
|
| isReadUncommittedMode | | boolean isReadUncommittedMode(LockMode lockMode)(Code) | | Returns whether the given lock mode will cause a read-uncommitted when
used with this cursor, taking into account the default cursor
configuration.
|
| setNonCloning | | void setNonCloning(boolean nonCloning)(Code) | | |
| trace | | void trace(Level level, String methodName, DatabaseEntry key, DatabaseEntry data, LockMode lockMode)(Code) | | Send trace messages to the java.util.logger. Don't rely on the logger
alone to conditionalize whether we send this message, we don't even want
to construct the message if the level is not enabled.
