Constructor Detail

OPAQUE

public OPAQUE(OpaqueDescriptor type,
              java.sql.Connection conn,
              java.lang.Object value)
       throws java.sql.SQLException

Constructor. The raw bytes are computed at this time or a copy of attributes is made. In any event the caller is free to modify the array without affecting the values held in the OPAQUE.

Parameters:

type - the SQLStructType used to convert the type to

attributes - the array specifying the attributes to be converted to raw bytes.

Throws:

java.sql.SQLException

See Also:

oracle.sql.SQLStructType

Method Detail

getSQLTypeName

public java.lang.String getSQLTypeName()
                                throws java.sql.SQLException

Implements the Struct interface function Retrieves the SQL type name of the SQL structured type that this Struct object represents.

Throws:

java.sql.SQLException - if a database access error occurs

getDescriptor

public OpaqueDescriptor getDescriptor()
                               throws java.sql.SQLException

Oracle extension. Return the OpaqueDescriptor object that contains the type information.

Returns:

the type descriptor

Throws:

java.sql.SQLException

getValue

public java.lang.Object getValue()
                          throws java.sql.SQLException

Return the Opaque value.

Returns:

a Java object that represents the opaque value

Throws:

java.sql.SQLException

getBytesValue

public byte[] getBytesValue()
                     throws java.sql.SQLException

Return a byte array that represents the attributes into the format that is actually used in the database.

Returns:

a byte array that represents the opaque value

Throws:

java.sql.SQLException

isConvertibleTo

public boolean isConvertibleTo(java.lang.Class jClass)

Determines if datum object can be converted to a particular class

Specified by:

isConvertibleTo in class Datum

Parameters:

cls - Class to convert to

Returns:

true, if conversion to cls is permitted false, if conversion to cls is not permitted

toJdbc

public java.lang.Object toJdbc()
                        throws java.sql.SQLException

Returns the JDBC representation of the datum object

Specified by:

toJdbc in class Datum

Returns:

an object containing the JDBC value

Throws:

java.sql.SQLException - if conversion to JDBC representation results in an error

getJavaSqlConnection

public java.sql.Connection getJavaSqlConnection()
                                         throws java.sql.SQLException

Description copied from class: DatumWithConnection

Oracle extension Return the java.sql.Connection associated with the receiver. Since 9.0.0 not all Oracle JDBC connection objects are assignment compatible with oracle.jdbc.driver.OracleConnection. If the connection is wrapped, return the outermost wrapper.

Overrides:

getJavaSqlConnection in class DatumWithConnection

Returns:

the connection

Throws:

java.sql.SQLException - if an error occurs
