AccessibleRelationSet
public AccessibleRelationSet(AccessibleRelation[] relations)
Create a relation set initialized with the given relations, duplicates are
ignored.
relations - the relations to insert
add
public boolean add(AccessibleRelation relation)
Add a new relation to the current set. If the relation is already in
the set, the targets are merged with the existing relation, possibly
resulting in an object being in the target list more than once. Do not
add a relation with a null key, as it will cause problems later.
relation - the relation to add
- true if the set was modified, which is always the case
addAll
public void addAll(AccessibleRelation[] array)
Add all of the relations to the current set. Duplicates are ignored.
array - the array of relations to add
clear
public void clear()
Clear all relations in the set.
contains
public boolean contains(String key)
Check if the relation key is in the set.
key - the relation to locate
get
public AccessibleRelation get(String key)
Get the relation that matches the key.
key - the relation to locate
- the relation in the set, or null
remove
public boolean remove(AccessibleRelation relation)
Remove a relation from the set. If a relation was removed, return true.
Note that this uses AccessibleRelation.equals, which defaults to ==, so a
relation with the same key may still exist in the set afterwords.
relation - the state to remove
size
public int size()
Return the number of relations in the set.
toString
public String toString()
Return a localized, comma-separated string representing all relations
in the set. This is in arbitrary order.
- toString in interface Object
- the string representation
