|
| public void | setTopLinkAttributeName(java.lang.String attributeName)Set the mapping attribute name, used to raise change events.
This is required if the change listener is set.
this.attributeName = attributeName;
|
| public void | setValueHolder(oracle.toplink.essentials.indirection.ValueHolderInterface valueHolder)Set the value holder.
Note that the delegate must be cleared out.
this.delegate = null;
this.valueHolder = valueHolder;
|
| public int | size()
return this.getDelegate().size();
|
| public java.lang.Object[] | toArray()
return this.getDelegate().toArray();
|
| public java.lang.Object[] | toArray(java.lang.Object[] a)
return this.getDelegate().toArray(a);
|
| public java.lang.String | toString()Use the delegate's #toString(); but wrap it with braces to indicate
there is a bit of indirection.
Don't allow this method to trigger a database read.
