Class ProjectHelper2.RootHandler

public static class ProjectHelper2.RootHandler extends DefaultHandler

Handler for ant processing. Uses a stack of AntHandlers to implement each element ( the original parser used a recursive behavior, with the implicit execution stack )

Constructor Summary
	RootHandler(AntXMLContext context, ProjectHelper2.AntHandler rootHandler) Creates a new RootHandler instance.

Method Summary
void	characters(char[] buf, int start, int count) Handle text within an element, calls currentHandler.characters.
void	endElement(String uri, String name, String qName) Handles the end of an element.
void	endPrefixMapping(String prefix) End a namepace prefix to uri mapping
ProjectHelper2.AntHandler	getCurrentAntHandler() Returns the current ant handler object.
InputSource	resolveEntity(String publicId, String systemId) Resolves file: URIs relative to the build file.
void	setDocumentLocator(Locator locator) Sets the locator in the project helper for future reference.
void	startElement(String uri, String tag, String qname, Attributes attrs) Handles the start of a project element.
void	startPrefixMapping(String prefix, String uri) Start a namespace prefix to uri mapping

Constructor Detail

RootHandler

public RootHandler(AntXMLContext context, ProjectHelper2.AntHandler rootHandler)

Creates a new RootHandler instance.

Parameters: context The context for the handler. rootHandler The handler for the root element.

Method Detail

characters

public void characters(char[] buf, int start, int count)

Handle text within an element, calls currentHandler.characters.

Parameters: buf A character array of the test. start The start offset in the array. count The number of characters to read.

Throws: SAXParseException if an error occurs

endElement

public void endElement(String uri, String name, String qName)

Handles the end of an element. Any required clean-up is performed by the onEndElement() method and then the original handler is restored to the parser.

Parameters: uri The namespace URI for this element. name The name of the element which is ending. Will not be null. qName The qualified name for this element.

Throws: SAXException in case of error (not thrown in this implementation)

endPrefixMapping

public void endPrefixMapping(String prefix)

End a namepace prefix to uri mapping

Parameters: prefix the prefix that is not mapped anymore

getCurrentAntHandler

public ProjectHelper2.AntHandler getCurrentAntHandler()

Returns the current ant handler object.

Returns: the current ant handler.

resolveEntity

public InputSource resolveEntity(String publicId, String systemId)

Resolves file: URIs relative to the build file.

Parameters: publicId The public identifier, or null if none is available. Ignored in this implementation. systemId The system identifier provided in the XML document. Will not be null.

Returns: an inputsource for this identifier

setDocumentLocator

public void setDocumentLocator(Locator locator)

Sets the locator in the project helper for future reference.

Parameters: locator The locator used by the parser. Will not be null.

startElement

public void startElement(String uri, String tag, String qname, Attributes attrs)

Handles the start of a project element. A project handler is created and initialised with the element name and attributes.

Parameters: uri The namespace uri for this element. tag The name of the element being started. Will not be null. qname The qualified name for this element. attrs Attributes of the element being started. Will not be null.

Throws: org.xml.sax.SAXParseException if the tag given is not "project"

startPrefixMapping

public void startPrefixMapping(String prefix, String uri)

Start a namespace prefix to uri mapping

Parameters: prefix the namespace prefix uri the namespace uri
