<p>This package implements SAX2-specific transformation APIs. It provides
|
|
44 |
classes which allow input from {@link org.xml.sax.ContentHandler}
|
|
45 |
events, and also classes that produce org.xml.sax.ContentHandler events. It
|
|
46 |
also provides methods to set the input source as an
|
|
47 |
{@link org.xml.sax.XMLReader}, or to use a
|
|
48 |
{@link org.xml.sax.InputSource} as the source. It also allows the
|
|
49 |
creation of a {@link org.xml.sax.XMLFilter}, which enables
|
|
50 |
transformations to "pull" from other transformations, and lets the transformer
|
|
51 |
to be used polymorphically as an {@link org.xml.sax.XMLReader}.</p>
|
|
52 |
<p>The {@link javax.xml.transform.sax.SAXSource} class allows the
|
|
53 |
setting of an {@link org.xml.sax.XMLReader} to be used for "pulling"
|
|
54 |
parse events, and an {@link org.xml.sax.InputSource} that may be used to
|
|
55 |
specify the SAX source.</p>
|
|
56 |
<p>The {@link javax.xml.transform.sax.SAXResult} class allows the
|
|
57 |
setting of a {@link org.xml.sax.ContentHandler} to be the receiver of
|
|
58 |
SAX2 events from the transformation.
|
|
59 |
<p>The {@link javax.xml.transform.sax.SAXTransformerFactory} extends
|
|
60 |
{@link javax.xml.transform.TransformerFactory} to provide factory
|
|
61 |
methods for creating {@link javax.xml.transform.sax.TemplatesHandler},
|
|
62 |
{@link javax.xml.transform.sax.TransformerHandler}, and
|
|
63 |
{@link org.xml.sax.XMLReader} instances.</p>
|
|
64 |
<p>To obtain a {@link javax.xml.transform.sax.SAXTransformerFactory},
|
|
65 |
the caller must cast the {@link javax.xml.transform.TransformerFactory}
|
|
66 |
instance returned from
|
|
67 |
{@link javax.xml.transform.TransformerFactory#newInstance}.
|
|
68 |
|
|
69 |
<p>The {@link javax.xml.transform.sax.TransformerHandler} interface
|
|
70 |
allows a transformation to be created from SAX2 parse events, which is a "push"
|
|
71 |
model rather than the "pull" model that normally occurs for a transformation.
|
|
72 |
Normal parse events are received through the
|
|
73 |
{@link org.xml.sax.ContentHandler} interface, lexical events such as
|
|
74 |
startCDATA and endCDATA are received through the
|
|
75 |
{@link org.xml.sax.ext.LexicalHandler} interface, and events that signal
|
|
76 |
the start or end of disabling output escaping are received via
|
|
77 |
{@link org.xml.sax.ContentHandler#processingInstruction}, with the
|
|
78 |
target parameter being
|
|
79 |
{@link javax.xml.transform.Result#PI_DISABLE_OUTPUT_ESCAPING} and
|
|
80 |
{@link javax.xml.transform.Result#PI_ENABLE_OUTPUT_ESCAPING}. If
|
|
81 |
parameters, output properties, or other features need to be set on the
|
|
82 |
Transformer handler, a {@link javax.xml.transform.Transformer} reference
|
|
83 |
will need to be obtained from
|
|
84 |
{@link javax.xml.transform.sax.TransformerHandler#getTransformer}, and
|
|
85 |
the methods invoked from that reference.
|
|
86 |
|
|
87 |
<p>The {@link javax.xml.transform.sax.TemplatesHandler} interface
|
|
88 |
allows the creation of {@link javax.xml.transform.Templates} objects
|
|
89 |
from SAX2 parse events. Once the {@link org.xml.sax.ContentHandler}
|
|
90 |
events are complete, the Templates object may be obtained from
|
|
91 |
{@link javax.xml.transform.sax.TemplatesHandler#getTemplates}. Note that
|
|
92 |
{@link javax.xml.transform.sax.TemplatesHandler#setSystemId} should
|
|
93 |
normally be called in order to establish a base system ID from which relative
|
|
94 |
URLs may be resolved.
|
|
95 |
<p>The
|
|
96 |
{@link javax.xml.transform.sax.SAXTransformerFactory#newXMLFilter}
|
|
97 |
method allows the creation of a {@link org.xml.sax.XMLFilter}, which
|
|
98 |
encapsulates the SAX2 notion of a "pull" transformation. The following
|
|
99 |
illustrates several transformations chained together. Each filter points to a
|
|
100 |
parent {@link org.xml.sax.XMLReader}, and the final transformation is
|
|
101 |
caused by invoking {@link org.xml.sax.XMLReader#parse} on the final
|
|
102 |
reader in the chain.</p>
