java.lang.Object
javax.sql.rowset.serial.SerialJavaObject
- All Implemented Interfaces:
Serializable
,Cloneable
A serializable mapping in the Java programming language of an SQL
JAVA_OBJECT
value. Assuming the Java object
implements the Serializable
interface, this class simply wraps the
serialization process.
If however, the serialization is not possible because
the Java object is not immediately serializable, this class will
attempt to serialize all non-static members to permit the object
state to be serialized.
Static or transient fields cannot be serialized; an attempt to serialize
them will result in a SerialException
object being thrown.
Thread safety
A SerialJavaObject is not safe for use by multiple concurrent threads. If a SerialJavaObject is to be used by more than one thread then access to the SerialJavaObject should be controlled by appropriate synchronization.- Since:

getObject
Returns anObject
that is a copy of thisSerialJavaObject
object.- Returns:
- a copy of this
SerialJavaObject
object as anObject
in the Java programming language - Throws:
SerialException
- if the instance is corrupt
-
getFields
Returns an array ofField
objects that contains each field of the object that this helper class is serializing.- Returns:
- an array of

objects - Throws:
SerialException
- if an error is encountered accessing the serialized objectSecurityException
- If a security manager, s, is present and the caller's class loader is not the same as or an ancestor of the class loader for the class of the object being serialized and invocation ofs.checkPackageAccess()
denies access to the package of that class.- See Also:

equals
Compares this SerialJavaObject to the specified object. The result istrue
if and only if the argument is notnull
and is aSerialJavaObject
object that is identical to this object -
hashCode
public int hashCode()Returns a hash code for this SerialJavaObject. The hash code for aSerialJavaObject
object is taken as the hash code of theObject
it stores -
