Method Detail

setParserClass

public void setParserClass(String parserClassName)
                    throws ClassNotFoundException

Input: A string representing a classname that corresponds to a SAX 1.0 compliant * parser. Examples include: com.microstar.xml.SAXDriver (using the AElfred parser) and com.sun.xml.parser.ValidatingParser (using Sun's parser) Output: None. Process: Do a classForName on the passed string if the class-exists, set a class variable, PARSERCLASS, to hold it. otherwise, throw the resultant ClassNotFoundException

Throws:

ClassNotFoundException

setInputDocument

public void setInputDocument(Reader isr)

Input: A Reader object representing a stream that needs to be read by the SAX parser. Output: None. Process: Open the file or string reader and create a class org.xml.sax.InputSource object, INPUTDOCUMENT from it. Throw the IOException as necessary.

InputSource

setInputDocument

public void setInputDocument(InputStream in)

Input: A InputStream object resenting a set of XML that needs to be read by the SAX parser. Output: None. Process: Create a class org.xml.sax.InputSource object, INPUTDOCUMENT from it. Throw the IOException as necessary.

setInputDocument

public void setInputDocument(URL in)
                      throws IOException

Input: A URL object resenting a set of XML that needs to be read by the SAX parser. Output: None. Process: Open a Reader object and create a class org.xml.sax.InputSource object, INPUTDOCUMENT from it. Throw the IOException as necessary.

Throws:

IOException

setInputDocument

public void setInputDocument(String in)

Input: A String object resenting a set of XML that needs to be read by the SAX parser. Output: None. Process: convert the String to a CharArrayReader and create a class org.xml.sax.InputSource object, INPUTDOCUMENT from it. Throw the IOException as necessary.

                               IllegalAccessException

Input: A string representing a classname that corresponds to an InfoEngine class file that will handle the actual processing of the XML inputstream represented by INPUTDOCUMENT. Output: None. Process: Attempt to do a classForName on the passed string. If the class exists, set a class variable, DOCUMENTHANDLER to hold it. Otherwise, throw the resultant ClassNotFoundException.

Throws:

ClassNotFoundException
