Known Direct Subclasses

Attributes2Impl

Default implementation of the Attributes interface.

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.

This class provides a default implementation of the SAX2 Attributes interface, with the addition of manipulators so that the list can be modified or reused.

There are two typical uses of this class:

to take a persistent snapshot of an Attributes object in a startElement event; or
to construct or modify an Attributes object in a SAX2 driver or filter.

This class replaces the now-deprecated SAX1 AttributeListImpl class; in addition to supporting the updated Attributes interface rather than the deprecated AttributeList interface, it also includes a much more efficient implementation using a single array rather than a set of Vectors.

Public constructors

AttributesImpl

Added in API level 1

AttributesImpl ()

Construct a new, empty AttributesImpl object.

AttributesImpl

Added in API level 1

AttributesImpl (Attributes atts)

Copy an existing Attributes object.

This constructor is especially useful inside a startElement event.

Parameters
`atts`	`Attributes`: The existing Attributes object.

Public methods

addAttribute

Added in API level 1

void addAttribute (String uri, 
                String localName, 
                String qName, 
                String type, 
                String value)

Add an attribute to the end of the list.

For the sake of speed, this method does no checking to see if the attribute is already in the list: that is the responsibility of the application.

Parameters
`uri`	`String`: The Namespace URI, or the empty string if none is available or Namespace processing is not being performed.
`localName`	`String`: The local name, or the empty string if Namespace processing is not being performed.
`qName`	`String`: The qualified (prefixed) name, or the empty string if qualified names are not available.
`type`	`String`: The attribute type as a string.
`value`	`String`: The attribute value.

clear

Added in API level 1

void clear ()

Clear the attribute list for reuse.

Note that little memory is freed by this call: the current array is kept so it can be reused.

getIndex

Added in API level 1

int getIndex (String qName)

Look up an attribute's index by qualified (prefixed) name.

Parameters
`qName`	`String`: The qualified name.

Returns
`int`	The attribute's index, or -1 if none matches.

See also:

getIndex

Added in API level 1

int getIndex (String uri, 
                String localName)

Look up an attribute's index by Namespace name.

In many cases, it will be more efficient to look up the name once and use the index query methods rather than using the name query methods repeatedly.

Parameters
`uri`	`String`: The attribute's Namespace URI, or the empty string if none is available.
`localName`	`String`: The attribute's local name.

Returns
`int`	The attribute's index, or -1 if none matches.
