Class BFILE

  • All Implemented Interfaces:
    Serializable, oracle.jdbc.internal.ACProxyable, oracle.jdbc.internal.OracleBfile, oracle.jdbc.internal.OracleConcreteProxy, oracle.jdbc.internal.OracleDatumWithConnection, OracleBfile
    public class BFILE
extends DatumWithConnection
implements oracle.jdbc.internal.OracleBfile, oracle.jdbc.internal.OracleConcreteProxy
    Deprecated.
    Use oracle.jdbc.OracleBfile interface for declaration instead of using concrete class oracle.sql.BFILE.
    A class for Oracle specific data type BFILE. Use OracleBfile interface for declaration instead of using concrete class oracle.sql.BFILE. OracleBfile has methods declared for all opertions.

    Obtaining OracleBfile from a ResultSet

    oracle.jdbc.OracleBfile bfile = ((OracleResultSet)resultSet).getBFILE(...); There is no way to create OracleBfile on the client side.

        Description copied from interface: OracleBfile
        Returns a Publisher that publishes the content of this BFile beginning at the specified position. The argument to each call to Subscriber.onNext will contain an implementation defined number of bytes.

        Calling any method of this BFile except fileExists(), getDirAlias(), getName(), or one defined by Object between the time this method is called and the time when the returned publisher terminates will block.

        The returned publisher terminates once all subscribers have received Subscriber.onComplete, received Subscriber.onError, or cancelled their subscription.

        Asynchronous tasks initiated by this method will execute under the current AccessControlContext of the calling thread.

        publisherOracle in interface OracleBfile
        Parameters:
        position - the position at which to start reading from the BFILE value that this Bfile object represents; The first position is 1
        Returns:
        a Publisher of the content of this BFile
        Throws:
        SQLException - if a database error occurs or if position is less than 1
