Interface LSSerializerFilter
- NodeFilter
LSSerializerFilter
s provide applications the ability to
examine nodes as they are being serialized and decide what nodes should
be serialized or not. The
LSSerializerFilter
interface is
based on the
NodeFilter
interface defined in [
DOM Level 2 Traversal and Range]
.
Document
,
DocumentType
,
DocumentFragment
,
Notation
,
Entity
, and children of
Attr
nodes are not passed to the filter.
The child nodes of an
EntityReference
node are only passed
to the filter if the
EntityReference
node is skipped by the
method
LSParserFilter.acceptNode()
.
When serializing an
Element
, the element is passed to the
filter before any of its attributes are passed to the filter. Namespace
declaration attributes, and default attributes (except in the case when "
discard-default-content" is set to
false
), are never passed
to the filter.
The result of any attempt to modify a node passed to a
LSSerializerFilter
is implementation dependent.
DOM applications must not raise exceptions in a filter. The effect of
throwing exceptions from a filter is DOM implementation dependent.
For efficiency, a node passed to the filter may not be the same as the
one that is actually in the tree. And the actual node (node object
identity) may be reused during the process of filtering and serializing a
document.

Document Object Model (DOM) Level 3 Load
and Save Specification.

int | getWhatToShow() - Tells the
LSSerializer what types of nodes to show to the
filter.
|
getWhatToShow
public int getWhatToShow()
Tells the
LSSerializer
what types of nodes to show to the
filter. If a node is not shown to the filter using this attribute, it
is automatically serialized. See
NodeFilter
for
definition of the constants. The constants
SHOW_DOCUMENT
,
SHOW_DOCUMENT_TYPE
,
SHOW_DOCUMENT_FRAGMENT
,
SHOW_NOTATION
, and
SHOW_ENTITY
are
meaningless here, such nodes will never be passed to a
LSSerializerFilter
.
Unlike [
DOM Level 2 Traversal and Range]
, the
SHOW_ATTRIBUTE
constant indicates that the
Attr
nodes are shown and passed to the filter.
The constants used here are defined in [
DOM Level 2 Traversal and Range]
.
