protected static final int SIZE_LIMIT
Threshold at which an instance is treated as a large attribute list.
- Field Value:
- 20
protected static final int TABLE_SIZE
Default table size.
- Field Value:
- 101
protected org.apache.xerces.util.XMLAttributesImpl.Attribute[] fAttributeTableView
Hashtable of attribute information. Provides an alternate view of the attribute specification.
protected int[] fAttributeTableViewChainState
Tracks whether each chain in the hash table is stale with respect to the current state of this object. A chain is stale if its state is not the same as the number of times the attribute table view has been used.
protected org.apache.xerces.util.XMLAttributesImpl.Attribute[] fAttributes
Attribute information.
protected boolean fIsTableViewConsistent
Indicates whether the table view contains consistent data.
protected int fLargeCount
Usage count for the attribute table view. Incremented each time all attributes are removed when the attribute table view is in use.
protected int fLength
Attribute count.
protected boolean fNamespaces
Namespaces.
protected int fTableViewBuckets
Actual number of buckets in the table view.
public XMLAttributesImpl()
Default constructor.
public XMLAttributesImpl(int tableSize)
- Parameters:
tableSize
- initial size of table view
public int addAttribute(org.apache.xerces.xni.QName name, String type, String value)
Adds an attribute. The attribute's non-normalized value of the attribute will have the same value as the attribute value until set using thesetNonNormalizedValue
method. Also, the added attribute will be marked as specified in the XML instance document unless set otherwise using thesetSpecified
method. Note: If an attribute of the same name already exists, the old values for the attribute are replaced by the new values.
- Specified by:
- addAttribute in interface org.apache.xerces.xni.XMLAttributes
- Parameters:
name
- The attribute name.type
- The attribute type. The type name is determined by the type specified for this attribute in the DTD. For example: "CDATA", "ID", "NMTOKEN", etc. However, attributes of type enumeration will have the type value specified as the pipe ('|') separated list of the enumeration values prefixed by an open parenthesis and suffixed by a close parenthesis. For example: "(true|false)".value
- The attribute value.
- Returns:
- Returns the attribute index.
public void addAttributeNS(org.apache.xerces.xni.QName name, String type, String value)
Adds an attribute. The attribute's non-normalized value of the attribute will have the same value as the attribute value until set using thesetNonNormalizedValue
method. Also, the added attribute will be marked as specified in the XML instance document unless set otherwise using thesetSpecified
method. This method differs fromaddAttribute
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 toaddAttribute
unless it has been determined that all the attribute names are unique.
- Parameters:
name
- the attribute nametype
- the attribute typevalue
- the attribute value
public org.apache.xerces.xni.QName checkDuplicatesNS()
Checks for duplicate expanded names (local part and namespace name pairs) in the attribute specification. If a duplicate is found its name is returned. This should be called once all the in-scope namespaces for the element enclosing these attributes is known, and after all the attributes have gone through namespace binding.
- Returns:
- the name of a duplicate attribute found in the search, otherwise null.
protected void cleanTableView()
Purges all elements from the table view.
