Constructor Detail

### RuntimeConfigurable

    public RuntimeConfigurable(java.lang.Object proxy,
                               java.lang.String elementTag)

  Sole constructor creating a wrapper for the specified object.

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

Method Detail

### setProxy

    public void setProxy(java.lang.Object proxy)

  Sets the element to configure.

  Parameters:
    `proxy` - The element to configure. Must not be `null`.

### getProxy

    public java.lang.Object getProxy()

  Get the object for which this RuntimeConfigurable holds the configuration information

  Returns:
    the object whose configure is held by this instance.

### getPolyType

    public java.lang.String getPolyType()

  get the polymorphic type for this element

  Returns:
    the ant component type name, null if not set

### setPolyType

    public void setPolyType(java.lang.String polyType)

  set the polymorphic type for this element

  Parameters:
    `polyType` - the ant component type name, null if not set

### setAttributes

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

  Deprecated.

  Sets the attributes for the wrapped element.

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

### setAttribute

    public void setAttribute(java.lang.String name,
                             java.lang.String value)

  Set an attribute to a given value

  Parameters:
    `name` - the name of the attribute.
    `value` - the attribute's value.

### getAttributeMap

    public java.util.Hashtable getAttributeMap()

  Return the attribute map.

  Returns:
    Attribute name to attribute value map

### getAttributes

    public org.xml.sax.AttributeList getAttributes()

  Deprecated.

  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`.

### getChildren

    public java.util.Enumeration getChildren()

  Returns an enumeration of all child wrappers.

  Returns:
    an enumeration of the child wrappers.
  Since:
    Ant 1.5.1

### 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.

### getText

    public java.lang.StringBuffer getText()

  Get the text content of this element. Various text chunks are concatenated, there is no way ( currently ) of keeping track of multiple fragments.

  Returns:
    the text content of this element.

### 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.

### reconfigure

    public void reconfigure(Project p)

  Reconfigure the element, even if it has already been configured.

  Parameters:
    `p` - the project instance for this configuration.

### applyPreSet

    public void applyPreSet(RuntimeConfigurable r)

  Apply presets, attributes and text are set if not currently set. nested elements are prepended.

  Parameters:
    `r` - a `RuntimeConfigurable` value
