whether or not different objects can have the same name field value.

validateName

public void validateName(java.lang.String type,

                  throws InvalidNameException

Throws:

InvalidNameException - if the name is invalid. The message should detail why it is invalid.

getDefaultName

public java.lang.String getDefaultName(java.lang.String type,
                                       java.lang.String objName)

By default this method produces an init-capped version of the database object name.

                                     java.lang.String otherName)

Returns the label for the item in the shuttle picker that should be displayed for an item representing an object (e.g. Table) that has been given another name.

Parameters:

objectName - the name of the real database object chosen

Returns:

the String to use in the item in the shuttle list.
