AttributeSet as1 + as2

 public static AttributeSet intersection(Set s)

Gives an AttributeSet which is the intersection of all AttributeSets in the Set s. If one of the elements in s is not an AttributeSet, null is returned.

Parameters:

s - A Set of AttributeSets.

Returns:

AttributeSet The intersection of all AttributeSets in s. When s does contain an element that is not an AttributeSet, null is returned.

 public static AttributeSet intersection(AttributeSet as1,
                                         AttributeSet as2)

Gives an AttributeSet containing all attributes which are in the AttributeSet as1 and also in as2.

Parameters:

as1 - First AttributeSet

as2 - Second AttributeSet

AttributeSet s1 intersection s2

 public static AttributeSet minus(AttributeSet as1,
                                  AttributeSet as2)

 public boolean isElement(Attribute a)

This method checks wether an Attribute is element of the Set.

 public boolean isSubset(AttributeSet as)

This method tests wether s is subset of this set.

Returns:

boolean true When s is a subset, false otherwise

 public int size()

Returns:

int The number of objects in the AttributeSet.

 public Attribute[] getAttributeArray()

Returns:

Attribute[] The elements of the set as an array. Note, that the sequence may be arbitrary.

 public boolean hasElementOfClass(Class c)

Tests whether this AttributeSet contains an Element of Class c.

Parameters:

s - c The Class to check for.

Returns:

s true when the AttributeSet contains any element of class c

 public Attribute getElementOfClass(Class c)

Retrieve the first element of Class c in AttributeSet.

Parameters:

s - c The Class to check for.

Returns:

s The first element of class c or null.

 public String toString()

No comment.

Overrides:

toString in class Object

 public AttributeSet flatCopy()

Copies the set; the contents of both sets is the _same_.

Returns:

AttributeSet A new set with references to the same Attributes as are in this.

 public Object clone() throws CloneNotSupportedException

In order for being cloneable by other classes, we have to override clone() to be public. Note that this does not do a deep clone of the contained Set.

Returns:

Object A (not deep)cloned Copy of this.

Throws: CloneNotSupportedException

When the superclass does not want to clone us. This should never ever happen.
