AttributeListImpl

extends Object
implements AttributeList
java.lang.Object
   ↳ org.xml.sax.helpers.AttributeListImpl

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This class implements a deprecated interface, AttributeList ; that interface has been replaced by Attributes , which is implemented in the AttributesImpl helper class.

Class Overview

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AttributeList implements the deprecated SAX1 AttributeList interface, and has been replaced by the new SAX2 AttributesImpl interface.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.

Public Constructors

public AttributeListImpl ()

Added in API level 1

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.

See Also

public AttributeListImpl ( AttributeList atts)

Added in API level 1

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.

Parameters
atts The attribute list to copy
See Also

Public Methods

public void addAttribute ( String name, String type, String value)

Added in API level 1

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.

Parameters
name The attribute name.
type The attribute type ("NMTOKEN" for an enumeration).
value The attribute value (must not be null).
See Also

public void clear ()

Added in API level 1

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.

See Also

public int getLength ()

Added in API level 1

Return the number of attributes in the list.

Returns
  • The number of attributes in the list.
See Also

public String getName (int i)

Added in API level 1

Get the name of an attribute (by position).

Parameters
i The position of the attribute in the list.
Returns
  • The attribute name as a string, or null if there is no attribute at that position.
See Also

public String getType ( String name)

Added in API level 1

Get the type of an attribute (by name).

Parameters
name The attribute name.
Returns
  • The attribute type as a string ("NMTOKEN" for an enumeration, and "CDATA" if no declaration was read).
See Also

public String getType (int i)

Added in API level 1

Get the type of an attribute (by position).

Parameters
i The position of the attribute in the list.
Returns
  • The attribute type as a string ("NMTOKEN" for an enumeration, and "CDATA" if no declaration was read), or null if there is no attribute at that position.
See Also

public String getValue ( String name)

Added in API level 1

Get the value of an attribute (by name).

Parameters
name The attribute name.
Returns
  • the named attribute's value or null, if the attribute does not exist.
See Also

public String getValue (int i)

Added in API level 1

Get the value of an attribute (by position).

Parameters
i The position of the attribute in the list.
Returns
  • The attribute value as a string, or null if there is no attribute at that position.
See Also

public void removeAttribute ( String name)

Added in API level 1

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.

Parameters
name The attribute name.
See Also

public void setAttributeList ( AttributeList atts)

Added in API level 1

Set the attribute list, discarding previous contents.

This method allows an application writer to reuse an attribute list easily.

Parameters
atts The attribute list to copy.
