Constructor Detail

XmlReaderContentHandler back to summary

public XmlReaderContentHandler(RowSet r)

Constructs a new XmlReaderContentHandler object that will assist the SAX parser in reading a WebRowSet object in the format of an XML document. In addition to setting some default values, this constructor creates three HashMap objects, one for properties, one for metadata, and one for data. These hash maps map the strings sent by the SAX parser to integer constants so that they can be compared more efficiently in switch statements.

Parameters

r:RowSet: the RowSet object in XML format that will be read

Method Detail

applyUpdates	back to summary
private void applyUpdates() throws SAXException

characters back to summary

public void characters(char[] ch, int start, int length) throws SAXException

Overrides org.xml.sax.helpers.DefaultHandler.characters.

Implements org.xml.sax.ContentHandler.characters.

Sets a property, metadata, or data value with the characters in the given array of characters, starting with the array element indicated by start and continuing for length number of characters.

The SAX parser invokes this method and supplies the character array, start position, and length parameter values it got from parsing the XML document. An application programmer never invokes this method directly.

Parameters

ch:char[]: an array of characters supplied by the SAX parser, all or part of which will be used to set a value
start:int: the position in the given array at which to start
length:int: the number of consecutive characters to use

Exceptions

SAXException:

Doc from org.xml.sax.helpers.DefaultHandler.characters.

Any SAX exception, possibly wrapping another exception.

endDocument

back to summary

public void endDocument() throws SAXException

Overrides org.xml.sax.helpers.DefaultHandler.endDocument.

Implements org.xml.sax.ContentHandler.endDocument.

Doc from org.xml.sax.helpers.DefaultHandler.endDocument.

Receive notification of the end of the document.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the end of a document (such as finalising a tree or closing an output file).

Exceptions

SAXException:: Any SAX exception, possibly wrapping another exception.

endElement back to summary

public void endElement(String uri, String lName, String qName) throws SAXException

Overrides org.xml.sax.helpers.DefaultHandler.endElement.

Implements org.xml.sax.ContentHandler.endElement.

Sets the value for the given element if name is one of the array elements in the fields properties, colDef, or data and this XmlReaderContentHandler object's state is not INITIAL. If the state is INITIAL, this method does nothing.

If the state is METADATA and the argument supplied is "metadata", the rowset's metadata is set. If the state is PROPERTIES, the appropriate property is set using the given name to determine the appropriate value. If the state is DATA and the argument supplied is "data", this method sets the state to INITIAL and returns. If the argument supplied is one of the elements in the field data, this method makes the appropriate changes to the rowset's data.

Parameters

lName:String: the name of the element; either (1) one of the array elements in the fields properties, colDef, or data or (2) one of the RowSet elements "properties", "metadata", or "data"

Annotations

@SuppressWarnings:fallthrough

Exceptions

SAXException:: if a general SAX error occurs

error back to summary

public void error(SAXParseException e) throws SAXParseException

Overrides org.xml.sax.helpers.DefaultHandler.error.

Implements org.xml.sax.ErrorHandler.error.

Throws the given SAXParseException object. This exception was originally thrown by the SAX parser and is passed to the method error when the SAX parser invokes it.

Parameters

e:SAXParseException: the SAXParseException object to throw

getBigDecimalValue	back to summary

getPresentRow back to summary

private Row getPresentRow(WebRowSetImpl rs) throws SQLException

Returns the current row of this Rowsetobject. The ResultSet's cursor is positioned at the Row which is needed

Returns:Row: the Row object on which the RowSet implementation objects's cursor is positioned

getShortValue	back to summary
private short getShortValue(String s)

getState back to summary

private int getState()

Retrieves the current state of this XmlReaderContentHandler object's rowset, which is stored in the document handler's state field.

Returns:int: one of the following constants: XmlReaderContentHandler.PROPERTIES XmlReaderContentHandler.METADATA XmlReaderContentHandler.DATA XmlReaderContentHandler.INITIAL

getStringValue	back to summary
private String getStringValue(String s)

getTag	back to summary
private int getTag()

getTimestampValue	back to summary
private Timestamp getTimestampValue(String s)

getTimeValue	back to summary
private Time getTimeValue(String s)

initMaps back to summary

private void initMaps()

Creates and initializes three new HashMap objects that map the strings returned by the SAX parser to Integer objects. The strings returned by the parser will match the strings that are array elements in this XmlReaderContentHandler object's properties, colDef, or data fields. For each array element in these fields, there is a corresponding constant defined. It is to these constants that the strings are mapped. In the HashMap objects, the string is the key, and the integer is the value.

The purpose of the mapping is to make comparisons faster. Because comparing numbers is more efficient than comparing strings, the strings returned by the parser are mapped to integers, which can then be used in a switch statement.

insertValue	back to summary
private void insertValue(String s) throws SQLException

notationDecl

back to summary

public void notationDecl(String name, String publicId, String systemId)

Overrides org.xml.sax.helpers.DefaultHandler.notationDecl.

back to summary

public void startDocument() throws SAXException

Overrides org.xml.sax.helpers.DefaultHandler.startDocument.

Implements org.xml.sax.ContentHandler.startDocument.

Doc from org.xml.sax.helpers.DefaultHandler.startDocument.

Receive notification of the beginning of the document.

By default, do nothing. Application writers may override this method in a subclass to take specific actions at the beginning of a document (such as allocating the root node of a tree or creating an output file).

Exceptions

SAXException:: Any SAX exception, possibly wrapping another exception.

startElement back to summary

public void startElement(String uri, String lName, String qName, Attributes attributes) throws SAXException

Overrides org.xml.sax.helpers.DefaultHandler.startElement.

Implements org.xml.sax.ContentHandler.startElement.

Sets this XmlReaderContentHandler object's tag field if the given name is the key for a tag and this object's state is not INITIAL. The field is set to the constant that corresponds to the given element name. If the state is INITIAL, the state is set to the given name, which will be one of the sections PROPERTIES, METADATA, or DATA. In either case, this method puts this document handler in the proper state for calling the method endElement.

If the state is DATA and the tag is RowTag, DelTag, or InsTag, this method moves the rowset's cursor to the insert row and sets this XmlReaderContentHandler object's idx field to 0 so that it will be in the proper state when the parser calls the method endElement.

Parameters

lName:String: the name of the element; either (1) one of the array elements in the fields properties, colDef, or data or (2) one of the RowSet elements "properties", "metadata", or "data"
attributes:Attributes: org.xml.sax.AttributeList objects that are attributes of the named section element; may be null if there are no attributes, which is the case for WebRowSet objects

Exceptions

Overrides org.xml.sax.helpers.DefaultHandler.unparsedEntityDecl.

Implements org.xml.sax.DTDHandler.unparsedEntityDecl.

Doc from org.xml.sax.helpers.DefaultHandler.unparsedEntityDecl.

Receive notification of an unparsed entity declaration.

By default, do nothing. Application writers may override this method in a subclass to keep track of the unparsed entities declared in a document.

warning back to summary

public void warning(SAXParseException err) throws SAXParseException

Overrides org.xml.sax.helpers.DefaultHandler.warning.

Implements org.xml.sax.ErrorHandler.warning.

Prints a warning message to System.out giving the line number and uri for what caused the warning plus a message explaining the reason for the warning. This method is invoked by the SAX parser.
