oracle.javatools.db.datatypes.DataTypeID
public final class DataTypeID
INTERNAL USE ONLY. THIS CLASS IS NOT PART OF THE PUBLIC API. To retrieve DataTypes (and their IDs) use the DataType methods on a DBObjectProvider, or if working without a provider use the DataTypeRegistry.
DBObjectID implementation for DataTypes that belong to a provider (built-in types). The object is a bean that stores the name of the type and the provider class it is a built-in type for. To resolve the ID the DataTypeRegistry is used to lookup the name and provider. An appropriate instance of this object is assinged to every DataType registered with the DataTypeRegistry.

public java.lang.Object copyTo(java.lang.Object target)
Copyable
this
object to the specified copy
. If copy
is null
, then this method should create a new instance of this
class and proceed to copy the internal state to the newly created object. Generally, only the persistent state of the object should be copied, but whether or not it is appropriate to copy transient properties is at the discretion of the individual implementor.
Regardless of whether the copy occurs to an existing object or to a newly created object, the return value is object to which this
object's state was copied.
There is a standard implementation pattern for the copyTo
method that helps avoid problems that arise when a Copyable
object is subclassed. The pattern is:
The parameter passed into thepublic Object copyTo( Object target ) { final <this_class> copy = target != null ? (<this_class>) target : new <this_class>(); copyToImpl( copy ); return copy; } protected final void copyToImpl( <this_class> copy ) { super.copyToImpl( copy ); // if necessary // put code here for copying the properties of <this_class> }
copyToImpl
method is the same type of this
class. The responsibility of copyToImpl
is to copy the state of this
class through direct access of the fields. The copyToImpl
method should not use getters and setters since these may be overridden, causing the state of this
class to be incompletely copied.copyTo
in interface Copyable
target
- The target object to which the state of this
object should be copied. If target
is null
, then the copyTo
method will return a new instance of this
class.this
object was copied. If the target
was non-null
, then the return value is the same as the target
object that was passed in; otherwise, the return value is a new instance of this
class.protected void copyToImpl(DataTypeID target)
