 org.apache.xerces.util.XMLAttributesImpl
| XMLAttributesImpl | | public class XMLAttributesImpl implements XMLAttributes(Code) | | The XMLAttributesImpl class is an implementation of the XMLAttributes
interface which defines a collection of attributes for an element.
In the parser, the document source would scan the entire start element
and collect the attributes. The attributes are communicated to the
document handler in the startElement method.
The attributes are read-write so that subsequent stages in the document
pipeline can modify the values or change the attributes that are
propogated to the next stage.

| XMLAttributesImpl | | public XMLAttributesImpl(int tableSize)(Code) | |
Parameters:
tableSize - initial size of table view |
| addAttribute | | public int addAttribute(QName name, String type, String value)(Code) | | Adds an attribute. The attribute's non-normalized value of the
attribute will have the same value as the attribute value until
set using the setNonNormalizedValue method. Also,
the added attribute will be marked as specified in the XML instance
document unless set otherwise using the setSpecified
method.
Note: If an attribute of the same name already
exists, the old values for the attribute are replaced by the new
values.
Parameters:
name - The attribute name.
Parameters:
type - The attribute type. The type name is determined bythe type specified for this attribute in the DTD.For example: "CDATA", "ID", "NMTOKEN", etc. However,attributes of type enumeration will have the typevalue specified as the pipe ('|') separated list ofthe enumeration values prefixed by an open parenthesis and suffixed by a close parenthesis.For example: "(true|false)".
Parameters:
value - The attribute value. Returns the attribute index.

| addAttributeNS | | public void addAttributeNS(QName name, String type, String value)(Code) | | Adds an attribute. The attribute's non-normalized value of the
attribute will have the same value as the attribute value until
set using the setNonNormalizedValue method. Also,
the added attribute will be marked as specified in the XML instance
document unless set otherwise using the setSpecified
method.
This method differs from addAttribute in that it
does not check if an attribute of the same name already exists
in the list before adding it. In order to improve performance
of namespace processing, this method allows uniqueness checks
to be deferred until all the namespace information is available
after the entire attribute specification has been read.
Caution: If this method is called it should
not be mixed with calls to addAttribute unless
it has been determined that all the attribute names are unique.
Parameters:
name - the attribute name
Parameters:
type - the attribute type
Parameters:
value - the attribute value
