## Class XMLAttributesImpl

- java.lang.Object
- - org.apache.xerces.util.XMLAttributesImpl

- All Implemented Interfaces:
    org.apache.xerces.xni.XMLAttributes

      public class XMLAttributesImpl
      extends java.lang.Object
      implements org.apache.xerces.xni.XMLAttributes

  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.

          public int getIndexFast(java.lang.String qName)

      Look up the index of an attribute by XML 1.0 qualified name.

      Note: This method uses reference comparison, and thus should only be used internally. We cannot use this method in any code exposed to users as they may not pass in unique strings.

      Parameters:
        `qName` - The qualified (prefixed) name.
      Returns:
        The index of the attribute, or -1 if it does not appear in the list.

    - #### addAttributeNS

          public void addAttributeNS(org.apache.xerces.xni.QName name,
                            java.lang.String type,
                            java.lang.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 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
        `type` - the attribute type
        `value` - the attribute value
      See Also:
        `setNonNormalizedValue(int, java.lang.String)`, `setSpecified(int, boolean)`, `checkDuplicatesNS()`

    - #### checkDuplicatesNS

          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.

    - #### getIndexFast

          public int getIndexFast(java.lang.String uri,
                         java.lang.String localPart)

      Look up the index of an attribute by Namespace name.

      Note: This method uses reference comparison, and thus should only be used internally. We cannot use this method in any code exposed to users as they may not pass in unique strings.

      Parameters:
        `uri` - The Namespace URI, or null if the name has no Namespace URI.
        `localPart` - The attribute's local name.
      Returns:
        The index of the attribute, or -1 if it does not appear in the list.

      Returns:
        the position in the table view where the given attribute would be hashed

    - #### getTableViewBucket

          protected int getTableViewBucket(java.lang.String localpart,

      Returns the position in the table view where the given attribute name would be hashed.
      Parameters:
