Constructor Detail

DBObjectSet

public DBObjectSet()

Constructs a new Set for uniquely storing DBObjects in name and type order whilst guarenteeing not to "build" the properties of the object using the equals method.

When ordering the objects, the name will be considered before the type.

DBObjectSet

public DBObjectSet(java.util.Collection<? extends T> c)

Constructs a new set containing the elements in the specified collection.

Parameters:

c - the collection whose elements are to be placed into this set
