Class AttributesImpl

java.lang.Object
  |

Default implementation of the Attributes interface.

This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY.

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

There are two typical uses of this class:

  1. to take a persistent snapshot of an Attributes object
  2. to construct or modify an Attributes object in a SAX2 driver or filter.
class; in addition to supporting the updated Attributes implementation using a single array rather than a set of Vectors.

Since:
SAX 2.0
Version:
2.0

          Copy an existing Attributes object.

AttributesImpl

public AttributesImpl()
Construct a new, empty AttributesImpl object.

Return an attribute's local name.
Parameters:
index - The attribute's index (zero-based).

The attribute's type, "CDATA" if the type is unknown, or null

getValue

public java.lang.String getValue(int index)
Return an attribute's value by index.

getIndex

public int getIndex(java.lang.String uri,
                    java.lang.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 - The attribute's Namespace URI, or the empty

getIndex

public int getIndex(java.lang.String qName)
Look up an attribute's index by qualified (prefixed) name.

getType

public java.lang.String getType(java.lang.String uri,
                                java.lang.String localName)
Look up an attribute's type by Namespace-qualified name.
Parameters:
uri - The Namespace URI, or the empty string for a name with no explicit Namespace URI.
localName - The local name.
Returns:
The attribute's type, or null if there is no

public java.lang.String getType(java.lang.String qName)
Look up an attribute's type by qualified (prefixed) name.
Parameters:
qName - The qualified name.
Returns:
The attribute's type, or null if there is no

getValue

getValue

public java.lang.String getValue(java.lang.String qName)
Look up an attribute's value by qualified (prefixed) name.
Parameters:
qName - The qualified name.
Returns:
The attribute's value, or null if there is no

clear

public void clear()
Clear the attribute list for reuse.

Note that no memory is actually freed by this call: the current arrays are kept so that they can be reused.

setAttributes 


Copy an entire Attributes object.

 
It may be more efficient to reuse an existing object
 rather than constantly allocating new ones.








Parameters:
atts - The attributes to copy.










addAttribute


public void addAttribute(java.lang.String uri,
                         java.lang.String localName,
                         java.lang.String qName,
                         java.lang.String type,
                         java.lang.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 - The Namespace URI, or the empty string if
        none is available or Namespace processing is not
        being performed.
localName - The local name, or the empty string if
        Namespace processing is not being performed.
qName - The qualified (prefixed) name, or the empty string
        if qualified names are not available.
type - The attribute type as a string.
value - The attribute value.










setAttribute


public void setAttribute(int index,
                         java.lang.String uri,

                         java.lang.String type,
                         java.lang.String value)




Set an attribute in the list.

 
For the sake of speed, this method does no checking
 for name conflicts or well-formedness: such checks are the
 responsibility of the application.
