Method Details- 
onStartElementpublic void onStartElement(String uri, String tag, String qname, Attributes attrs, AntXMLContext context) throws SAXParseException 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.- Overrides:
- onStartElementin class- ProjectHelper2.AntHandler
- 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)
 
- 
characterspublic void characters(char[] buf, int start, int count, AntXMLContext context) throws SAXParseException Adds text to the task, using the wrapper- Overrides:
- charactersin class- ProjectHelper2.AntHandler
- 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.

onStartChildpublic ProjectHelper2.AntHandler onStartChild(String uri, String tag, String qname, Attributes attrs, AntXMLContext context) throws SAXParseException 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.- Overrides:
- onStartChildin class- ProjectHelper2.AntHandler
- 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
 
- 
onEndElementHandles the end of the element. This pops the wrapper from the context.- Overrides:
- onEndElementin class- ProjectHelper2.AntHandler
- Parameters:
- uri- The namespace URI for the element.
- tag- The name of the element.
