Constructor Detail

ToHTMLStream

public ToHTMLStream()
Default constructor.
Method Detail

setSpecialEscapeURLs

public void setSpecialEscapeURLs(boolean bool)
Tells if the formatter should use special URL escaping.
Parameters:
bool - True if URLs should be specially escaped with the %xx form.

setOmitMetaTag

public void setOmitMetaTag(boolean bool)
Tells if the formatter should omit the META tag.
Parameters:
bool - True if the META tag should be omitted.

setOutputFormat

public void setOutputFormat(java.util.Properties format)
Specifies an output format for this serializer. It the serializer has already been associated with an output format, it will switch to the new format. This method should not be called while the serializer is in the process of serializing a document. This method can be called multiple times before starting the serialization of a particular result-tree. In principle all serialization parameters can be changed, with the exception of method="html" (it must be method="html" otherwise we shouldn't even have a ToHTMLStream object here!)
Parameters:
format - The output format or serialzation parameters to use.
Overrides:
setOutputFormat in class ToStream

getElemDesc

public static final ElemDesc getElemDesc(java.lang.String name)

characters

public final void characters(char[] chars,

                      throws SAXException
Receive notification of character data.

The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity, so that the Locator provides useful information.

The application must not attempt to read from the array outside of the specified range.

Note that some parsers will report whitespace using the ignorableWhitespace() method rather than this one (validating parsers must do so).

Parameters:
chars - The characters from the XML document.
start - The start position in the array.
length - The number of characters to read from the array.
Throws:
SAXException - Any SAX exception, possibly wrapping another exception.
SAXException -  
Overrides:
