List of openSequence() Examples

Examples of openSequence()

com.sleepycat.je.Database.openSequence()
Opens a sequence in the database. @param txn For a transactional database, an explicit transaction maybe specified, or null may be specified to use auto-commit. For a non-transactional database, null must be specified. @param key The key {@link DatabaseEntry} of the sequence. @param config The sequence attributes. If null, default attributes areused. @return a new Sequence handle. @throws SequenceExistsException if the sequence record already existsand the {@code SequenceConfig ExclusiveCreate} parameter is true. @throws SequenceNotFoundException if the sequence record does not existand the {@code SequenceConfig AllowCreate} parameter is false. @throws OperationFailureException if one of the Read Operation Failures occurs. If the sequence does not exist and the {@link SequenceConfig#setAllowCreate AllowCreate} parameter is true, then oneof the Write Operation Failures may also occur. @throws EnvironmentFailureException if an unexpected, internal orenvironment-wide failure occurs. @throws UnsupportedOperationException if this database is read-only, orthis database is configured for duplicates. @throws IllegalStateException if the Sequence record is deleted byanother thread during this method invocation, or the database has been closed. @throws IllegalArgumentException if an invalid parameter is specified,for example, an invalid {@code SequenceConfig} parameter.
com.sun.jmx.snmp.BerDecoder.openSequence()
Fetch a sequence header. The decoder computes the end position of the sequence and push it on its stack. @exception BerException Current position does not point to a sequence header.
com.sun.jmx.snmp.BerEncoder.openSequence()
Open a sequence. The encoder push the current position on its stack.
