Constructor Detail

AccessibleRelationSet

public AccessibleRelationSet()

Create an empty relation set.

---

AccessibleRelationSet

public AccessibleRelationSet(AccessibleRelation[] relations)

Create a relation set initialized with the given relations, duplicates are ignored.

Method Detail

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.

---

addAll

public void addAll(AccessibleRelation[] array)

Add all of the relations to the current set. Duplicates are ignored.

---

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.

---

clear

public void clear()

Clear all relations in the set.

---

size

public int size()

Return the number of relations in the set.

---

contains

public boolean contains(java.lang.String key)

Check if the relation key is in the set.

---

get

public AccessibleRelation get(java.lang.String key)

Get the relation that matches the key.

---

toArray

public AccessibleRelation[] toArray()

Return the relation set as an array.

---

toString

public java.lang.String toString()

Return a localized, comma-separated string representing all relations in the set. This is in arbitrary order.
