Method Detail

characters

public void characters(char[] buf, int start, int count, AntXMLContext context)
Adds text to the task, using the wrapper

Parameters: buf A character array of the text within the element. Will not be null. start The start element in the array. count The number of characters to read from the array. context The current context.

Throws: SAXParseException if the element doesn't support text

onEndElement

public void onEndElement(String uri, String tag, AntXMLContext context)
Handles the end of the element. This pops the wrapper from the context.

Parameters: uri The namespace URI for the element. tag The name of the element. context The current context.

onStartChild

public ProjectHelper2.AntHandler onStartChild(String uri, String tag, String qname, Attributes attrs, AntXMLContext context)
Handles the start of an element within a target. Task containers will always use another task handler, and all other tasks will always use a nested element handler.

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. context The current context.

Returns: The handler for elements.

Throws: SAXParseException if an error occurs when initialising the appropriate child handler

onStartElement

public void onStartElement(String uri, String tag, String qname, Attributes attrs, AntXMLContext context)
Initialisation routine called after handler creation with the element name and attributes. This configures the element with its attributes and sets it up with its parent container (if any). Nested elements are then added later as the parser encounters them.

Parameters: uri The namespace URI for this element. tag Name of the element which caused this handler to be created. Must not be null. qname The qualified name for this element. attrs Attributes of the element which caused this handler to be created. Must not be null. context The current context.

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