List of openCursor() Examples

Examples of openCursor()

com.sleepycat.db.Database.openCursor()
Return a cursor into the database.
@param txn To use a cursor for writing to a transactional database, an explicit transaction must be specified. For read-only access to a transactional database, the transaction may be null. For a non-transactional database, the transaction must be null.
To transaction-protect cursor operations, cursors must be opened and closed within the context of a transaction, and the txn parameter specifies the transaction context in which the cursor will be used.
@param config The cursor attributes. If null, default attributes are used.
@return A database cursor.
@throws DatabaseException if a failure occurs.
com.sleepycat.je.Database.openCursor()
Returns a cursor into the database. @param txn the transaction used to protect all operations performed withthe cursor, or null if the operations should not be transaction protected. If the database is non-transactional, null must be specified. For a transactional database, the transaction is optional for read-only access and required for read-write access. @param cursorConfig The cursor attributes. If null, default attributesare used. @return A database cursor. @throws com.sleepycat.je.rep.DatabasePreemptedException in a replicatedenvironment if the master has truncated, removed or renamed the database. @throws OperationFailureException if this exception occurred earlier andcaused the transaction to be invalidated. @throws EnvironmentFailureException if an unexpected, internal orenvironment-wide failure occurs. @throws IllegalStateException if the database has been closed. @throws IllegalArgumentException if an invalid parameter is specified,for example, an invalid {@code CursorConfig} parameter.
com.sleepycat.je.SecondaryDatabase.openCursor()
Obtain a cursor on a database, returning a SecondaryCursor.
nexj.core.persistence.Query.openCursor()
Opens a cursor on the instances specified by the query. @return The cursor.

Examples of com.sleepycat.je.SecondaryDatabase.openCursor()

       * SecondaryCursor and use additional method signatures for
       * retrieving the primary key also.  Or you can call
       * openSecondaryCursor() to avoid casting.

            txn = exampleEnv.beginTransaction(null, null);
            Cursor cursor = exampleSecDb.openCursor(txn, null);


            while (cursor.getNext(keyEntry, dataEntry, LockMode.DEFAULT) ==
                   OperationStatus.SUCCESS) {


                String key = (String) secKeyBinding.entryToObject(keyEntry);
