  `proxy` - The element to configure. Must not be `null`.
  `elementTag` - The tag name generating this element. Should not be `null`.

Method Detail

### setAttributes

    public void setAttributes(org.xml.sax.AttributeList attributes)

  Sets the attributes for the wrapped element.

  Parameters:
    `attributes` - List of attributes defined in the XML for this element. May be `null`.

### getAttributes

    public org.xml.sax.AttributeList getAttributes()

  Returns the list of attributes for the wrapped element.

  Returns:
    An AttributeList representing the attributes defined in the XML for this element. May be `null`.

### addChild

    public void addChild(RuntimeConfigurable child)

  Adds a child element to the wrapped element.

  Parameters:
    `child` - The child element wrapper to add to this one. Must not be `null`.

### addText

    public void addText(java.lang.String data)

  Adds characters from #PCDATA areas to the wrapped element.

  Parameters:
    `data` - Text to add to the wrapped element. Should not be `null`.

### addText

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

  Adds characters from #PCDATA areas to the wrapped element.

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

### getElementTag

    public java.lang.String getElementTag()

  Returns the tag name of the wrapped element.

  Returns:
    The tag name of the wrapped element. This is unlikely to be `null`, but may be.

### maybeConfigure

    public void maybeConfigure(Project p)
                        throws BuildException

  Configures the wrapped element and all its children. The attributes and text for the wrapped element are configured, and then each child is configured and added. Each time the wrapper is configured, the attributes and text for it are reset. If the element has an `id` attribute, a reference is added to the project as well.

  Parameters:
    `p` - The project containing the wrapped element. Must not be `null`.
  Throws:
    `BuildException` - if the configuration fails, for instance due to invalid attributes or children, or text being added to an element which doesn't accept it.

### maybeConfigure

    public void maybeConfigure(Project p,
                               boolean configureChildren)
                        throws BuildException

  Configures the wrapped element. The attributes and text for the wrapped element are configured. Each time the wrapper is configured, the attributes and text for it are reset. If the element has an `id` attribute, a reference is added to the project as well.

  Parameters:
    `p` - The project containing the wrapped element. Must not be `null`.
    `configureChildren` - Whether to configure child elements as well. if true, child elements will be configured after the wrapped element.
  Throws:
    `BuildException` - if the configuration fails, for instance due to invalid attributes or children, or text being added to an element which doesn't accept it.
