---|---|
boolean |
containsAttribute(Object name,
Object value)
Returns true if this set defines an attribute with the same
name and an equal value. |
boolean |
containsAttributes(AttributeSet attributes)
Returns true if this set defines all the attributes from the
given set with equal values. |
AttributeSet |
copyAttributes()
Returns an attribute set that is guaranteed not to change over time. |
Object |
getAttribute(Object key)
Fetches the value of the given attribute. |
int |
getAttributeCount()
Returns the number of attributes that are defined locally in this set. |
Enumeration<?> |
getAttributeNames()
Returns an enumeration over the names of the attributes that are defined locally in the set. |
AttributeSet |
getResolveParent()
Gets the resolving parent. |
boolean |
isDefined(Object attrName)

int getAttributeCount()
boolean isDefined(Object attrName)
attrName
- the attribute name
boolean isEqual(AttributeSet attr)
attr
- an attribute set
AttributeSet copyAttributes()
Object getAttribute(Object key)
key
- the non-null key of the attribute binding
Enumeration<?> getAttributeNames()
Enumeration
may be anything and are not constrained to
a particular Object
type.
This method never returns null
. For a set with no attributes, it
returns an empty Enumeration
.
boolean containsAttribute(Object name, Object value)
true
if this set defines an attribute with the same
name and an equal value. If such an attribute is not found locally,
it is searched through in the resolving parent hierarchy.
name
- the non-null attribute namevalue
- the value
true
if the set defines the attribute with an
equal value, either locally or through its resolving parent
NullPointerException
- if either name
or
value
is null
boolean containsAttributes(AttributeSet attributes)
true
if this set defines all the attributes from the
given set with equal values. If an attribute is not found locally,
it is searched through in the resolving parent hierarchy.
attributes
- the set of attributes to check against
true
if this set defines all the attributes with equal
values, either locally or through its resolving parent
NullPointerException
- if attributes
is null
AttributeSet getResolveParent()
