Known Direct Subclasses |
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:
startElement
event; orThis 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.

|
Copy an existing Attributes object.
This constructor is especially useful inside a
startElement
event.
atts | The existing Attributes object. |
---|
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.
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. |
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.
Look up an attribute's index by qualified (prefixed) name.
qName | The qualified name. |
---|
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.
uri | The attribute's Namespace URI, or the empty string if none is available. |
---|---|
localName | The attribute's local name. |
Return the number of attributes in the list.
Return an attribute's local name.
index | The attribute's index (zero-based). |
---|
Return an attribute's qualified (prefixed) name.
index | The attribute's index (zero-based). |
---|
Look up an attribute's type by qualified (prefixed) name.
qName | The qualified name. |
---|
Look up an attribute's type by Namespace-qualified name.
uri | The Namespace URI, or the empty string for a name with no explicit Namespace URI. |
---|---|
localName | The local name. |
Return an attribute's type by index.
index | The attribute's index (zero-based). |
---|
Return an attribute's Namespace URI.
index | The attribute's index (zero-based). |
---|
Look up an attribute's value by qualified (prefixed) name.
qName | The qualified name. |
---|
Return an attribute's value by index.
index | The attribute's index (zero-based). |
---|
Look up an attribute's value by Namespace-qualified name.
uri | The Namespace URI, or the empty string for a name with no explicit Namespace URI. |
---|---|
localName | The local name. |
Remove an attribute from the list.
index | The index of the attribute (zero-based). |
---|
ArrayIndexOutOfBoundsException | When the supplied index does not point to an attribute in the list. |
---|
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.
index | The index of the attribute (zero-based). |
---|---|
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 name, or the empty string if qualified names are not available. |
type | The attribute type as a string. |
value | The attribute value. |
ArrayIndexOutOfBoundsException | When the supplied index does not point to an attribute in the list. |
---|
Copy an entire Attributes object.
It may be more efficient to reuse an existing object rather than constantly allocating new ones.
atts | The attributes to copy. |
---|
Set the local name of a specific attribute.
index | The index of the attribute (zero-based). |
---|---|
localName | The attribute's local name, or the empty string for none. |
ArrayIndexOutOfBoundsException | When the supplied index does not point to an attribute in the list. |
---|
Set the qualified name of a specific attribute.

---|---|
type | The attribute's type. |
ArrayIndexOutOfBoundsException | When the supplied index does not point to an attribute in the list. |
---|
Set the Namespace URI of a specific attribute.
index | The index of the attribute (zero-based). |
---|---|
uri | The attribute's Namespace URI, or the empty string for none. |
