Class SimpleAttributeSet
- AttributeSet, Cloneable, MutableAttributeSet, Serializable
A set of attributes.
void | addAttribute(Object name, Object value)- Adds an attribute with the given
name and value
to the set.
|
void | addAttributes(AttributeSet attributes)- Adds all the attributes from
attributes to this set.
|
Object | clone()- Returns a clone of the attribute set.
|
boolean | containsAttribute(Object name, Object value)- Returns true if the given name and value represent an attribute
found either in this AttributeSet or in its resolve parent hierarchy.
|
boolean | containsAttributes(AttributeSet attributes)- Returns
true of this AttributeSet contains all
of the specified attributes.
|
AttributeSet | copyAttributes()- Creates and returns a copy of this
AttributeSet.
|
boolean | equals(Object obj)- Checks this set for equality with an arbitrary object.
|
Object | getAttribute(Object name)- Returns the value of the specified attribute, or
null if
there is no attribute with that name.
|
int | getAttributeCount()- Returns the number of attributes stored in this set, plus 1 if a parent
has been specified (the reference to the parent is stored as a special
attribute).
|
Enumeration | getAttributeNames()- Returns an enumeration of the attribute names.
|
AttributeSet | getResolveParent()- Returns the resolving parent.
|
int | hashCode()- Returns a hash code for this instance.
|
boolean | isDefined(Object attrName)- Returns
true if the given attribute is defined in this set,
and false otherwise.
|
boolean | isEmpty()- Returns
true if the set contains no attributes, and
false otherwise.
|
boolean | isEqual(AttributeSet attr)- Returns true if the given set has the same number of attributes
as this set and
containsAttributes(attr) returns
true.
|
void | removeAttribute(Object name)- Removes the attribute with the specified
name, if this
attribute is defined.
|
void | removeAttributes(Enumeration names)- Removes the attributes listed in
names.
|
void | removeAttributes(AttributeSet attributes)- Removes attributes from this set if they are found in the
given set.
|
void | setResolveParent(AttributeSet parent)- Sets the reolving parent for this set.
|

debugging purposes.

SimpleAttributeSet
public SimpleAttributeSet()
Creates a new attribute set that is initially empty.
SimpleAttributeSet
public SimpleAttributeSet(AttributeSet a)
Creates a new SimpleAttributeSet with the same attributes
and resolve parent as the specified set.
a - the attributes (null not permitted).
addAttribute
public void addAttribute(Object name,
Object value) Adds an attribute with the given name and value
to the set. If the set already contains an attribute with the given
name, the attribute value is updated.
- addAttribute in interface MutableAttributeSet
name - the attribute name (null not permitted).value - the value (null not permitted).
clone
public Object clone()
Returns a clone of the attribute set.
- clone in interface Object
- A clone of the attribute set.
containsAttribute
public boolean containsAttribute(Object name,
Object value) Returns true if the given name and value represent an attribute
found either in this AttributeSet or in its resolve parent hierarchy.
- containsAttribute in interface AttributeSet
name - the key for the attributevalue - the value for the attribute
- true if the attribute is found here or in this set's resolve
parent hierarchy
containsAttributes
public boolean containsAttributes(AttributeSet attributes)
Returns true of this AttributeSet contains all
of the specified attributes.
- containsAttributes in interface AttributeSet
attributes - the requested attributes
true of this AttributeSet contains all
of the specified attributes
equals
public boolean equals(Object obj)
Checks this set for equality with an arbitrary object.
- equals in interface Object
obj - the object (null permitted).
true if this set is equal to obj, and
false otherwise.
getAttribute
public Object getAttribute(Object name)
Returns the value of the specified attribute, or null if
there is no attribute with that name. If the attribute is not defined
directly in this set, the parent hierarchy (if there is one) will be
used.
- getAttribute in interface AttributeSet
name - the attribute (null not permitted).
getAttributeCount
public int getAttributeCount()
Returns the number of attributes stored in this set, plus 1 if a parent
has been specified (the reference to the parent is stored as a special
attribute). The attributes stored in the parent do NOT contribute
to the count.
- getAttributeCount in interface AttributeSet
isDefined
public boolean isDefined(Object attrName)
Returns true if the given attribute is defined in this set,
and false otherwise. The parent attribute set is not
checked.
- isDefined in interface AttributeSet
attrName - the attribute name (null not permitted).
isEmpty
public boolean isEmpty()
Returns true if the set contains no attributes, and
false otherwise. Note that the resolving parent is
stored as an attribute, so this method will return false if
a resolving parent is set.
true if the set contains no attributes, and
false otherwise.
isEqual
public boolean isEqual(AttributeSet attr)
Returns true if the given set has the same number of attributes
as this set and containsAttributes(attr) returns
true.
- isEqual in interface AttributeSet
attr - the attribute set (null not permitted).
removeAttribute
public void removeAttribute(Object name)
Removes the attribute with the specified name, if this
attribute is defined. This method will only remove an attribute from
this set, not from the resolving parent.
- removeAttribute in interface MutableAttributeSet
name - the attribute name (null not permitted).
removeAttributes
public void removeAttributes(AttributeSet attributes)
Removes attributes from this set if they are found in the
given set. Only attributes whose key AND value are removed.
Removes attributes only from this set, not from the resolving parent.
Since the resolving parent is stored as an attribute, if
attributes has the same resolving parent as this set, the
parent will be removed from this set.
- removeAttributes in interface MutableAttributeSet
attributes - the attributes (null not permitted).
setResolveParent
public void setResolveParent(AttributeSet parent)
Sets the reolving parent for this set. When looking up an attribute, if
it is not found in this set, then the resolving parent is also used for
the lookup.
Note that the parent is stored as an attribute, and will contribute 1 to
the count returned by
getAttributeCount().
- setResolveParent in interface MutableAttributeSet
parent - the parent attribute set (null not permitted).
toString
public String toString()
Returns a string representation of this instance, typically used for
debugging purposes.
- toString in interface Object
- A string representation of this instance.
