This class was deprecated
in API level 1.
This class implements a deprecated interface,
AttributeList
;
that interface has been replaced by
Attributes
,
which is implemented in the
AttributesImpl
helper class.
Default implementation for AttributeList.
This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY. See http://www.saxproject.org for further information.
AttributeList implements the deprecated SAX1 AttributeList
interface, and has been
replaced by the new SAX2 AttributesImpl
interface.
This class provides a convenience implementation of the SAX
AttributeList
interface. This
implementation is useful both for SAX parser writers, who can use
it to provide attributes to the application, and for SAX application
writers, who can use it to create a persistent copy of an element's
attribute specifications:
private AttributeList myatts; public void startElement (String name, AttributeList atts) { // create a persistent copy of the attribute list // for use outside this method myatts = new AttributeListImpl(atts); [...] }
Please note that SAX parsers are not required to use this class to provide an implementation of AttributeList; it is supplied only as an optional convenience. In particular, parser writers are encouraged to invent more efficient implementations.

Create an empty attribute list.
This constructor is most useful for parser writers, who will use it to create a single, reusable attribute list that can be reset with the clear method between elements.
Construct a persistent copy of an existing attribute list.
This constructor is most useful for application writers, who will use it to create a persistent copy of an existing attribute list.
atts | The attribute list to copy |
---|
Add an attribute to an attribute list.
This method is provided for SAX parser writers, to allow them to build up an attribute list incrementally before delivering it to the application.
name | The attribute name. |
---|---|
type | The attribute type ("NMTOKEN" for an enumeration). |
value | The attribute value (must not be null). |
Clear the attribute list.
SAX parser writers can use this method to reset the attribute list between DocumentHandler.startElement events. Normally, it will make sense to reuse the same AttributeListImpl object rather than allocating a new one each time.
Return the number of attributes in the list.
Get the name of an attribute (by position).
i | The position of the attribute in the list. |
---|
Get the type of an attribute (by name).
name | The attribute name. |
---|
Get the type of an attribute (by position).
i | The position of the attribute in the list. |
---|
Get the value of an attribute (by name).
name | The attribute name. |
---|
Get the value of an attribute (by position).
i | The position of the attribute in the list. |
---|
Remove an attribute from the list.
SAX application writers can use this method to filter an attribute out of an AttributeList. Note that invoking this method will change the length of the attribute list and some of the attribute's indices.
If the requested attribute is not in the list, this is a no-op.
name | The attribute name. |
---|
Set the attribute list, discarding previous contents.
This method allows an application writer to reuse an attribute list easily.
atts | The attribute list to copy. |
