Class NameBasedID

java.lang.Object

oracle.javatools.db.AbstractDBObjectID

oracle.javatools.db.BaseObjectID

oracle.javatools.db.NameBasedID

All Implemented Interfaces:

DBObjectID, Copyable

Direct Known Subclasses:

ConstraintID

public class NameBasedID
extends BaseObjectID

ID implementation that is name based. Store name and type of the object being referenced and is parented by another id, or alternatively stores the schema name if the object has no parent.

A NameBasedID will not resolve to any object that has the same name and type. It is used to identify a specific DBObject in a specific DBObjectProvider. For example a NameBasedID should not resolve to an object in a provider if that object has an IdentifiedBasedID. If you need to reference another object amiguously, without knowing specifically that it is identified by a NameBasedID, then use ReferenceID.

Method Detail

construct

public void construct(java.lang.String id)

INTERNAL USE ONLY Constructs the ID from the information in the string parameter. API users should use the createFromString method in BaseObjectID.

Specified by:

construct in class BaseObjectID

Parameters:

id - The ID in string form.

For internal use only. Application developers should not use this

equalsImpl

protected boolean equalsImpl(DBObjectID id,
                             boolean strict)

Description copied from class: AbstractDBObjectID

Subclasses should implement as appropriate to their equals implementation, calling AbstractDBObjectID.equalsImpl(AbstractDBObjectID) when appropriate.

Specified by:

equalsImpl in class AbstractDBObjectID

copyTo

public java.lang.Object copyTo(java.lang.Object target)

Description copied from interface: Copyable

Copies the internal state of 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:

    public 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>
    }
  

The parameter passed into the 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.

Parameters:

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.

Returns:

The object to which the state of 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.

toStringImpl

protected java.lang.String toStringImpl()

Specified by:

toStringImpl in class BaseObjectID
