Class ElementRenderer

java.lang.Object
  org.apache.myfaces.trinidadinternal.ui.BaseRenderer
      org.apache.myfaces.trinidadinternal.ui.ElementRenderer

All Implemented Interfaces:

Renderer

Direct Known Subclasses:

BaseLafRenderer, HTMLElementRenderer

Deprecated. This class comes from the old Java 1.2 UIX codebase and should not be used anymore.

@Deprecated
public class ElementRenderer
extends BaseRenderer

Renderer implementation that can output elements. This base implementation outputs no attributes; clients must override renderAttributes(). It will output the start and element tags, based on the return value of getElementName().

Constructor Detail

ElementRenderer

public ElementRenderer()

Deprecated.

Creates an ElementRenderer

Method Detail

getRenderer

public static Renderer getRenderer()

Deprecated.

Returns a shared instance of this renderer.

prerender

protected void prerender(UIXRenderingContext context,
                         UINode node)
                  throws java.io.IOException

Deprecated.

Called to render the portion before the contents. This implementation will output a start element tag and call renderAttributes(). Uses the element name returned by getElementName().

Overrides:

prerender in class BaseRenderer

Parameters:

context - the rendering context

node - the current UINode

Throws:

java.io.IOException

See Also:

renderAttributes(org.apache.myfaces.trinidadinternal.ui.UIXRenderingContext, org.apache.myfaces.trinidadinternal.ui.UINode), getElementName(org.apache.myfaces.trinidadinternal.ui.UIXRenderingContext, org.apache.myfaces.trinidadinternal.ui.UINode)

postrender

protected void postrender(UIXRenderingContext context,
                          UINode node)
                   throws java.io.IOException

Deprecated.

Called to render the portion after the contents. This implementation outputs a close element tag. Uses the element name returned by getElementName().

Overrides:

postrender in class BaseRenderer

Parameters:

context - the rendering context

node - the current UINode

Throws:

java.io.IOException

See Also:

getElementName(org.apache.myfaces.trinidadinternal.ui.UIXRenderingContext, org.apache.myfaces.trinidadinternal.ui.UINode)

renderAttributes

protected void renderAttributes(UIXRenderingContext context,
                                UINode node)
                         throws java.io.IOException

Deprecated.

Renders attributes of the current node. The default implementation does not render any attributes; subclasses should override this method if they need to output attributes.

Parameters:

context - the rendering context

node - the current UINode

Throws:

java.io.IOException

renderAttribute

protected void renderAttribute(UIXRenderingContext context,
                               java.lang.String name,
                               java.lang.Object value)
                        throws java.io.IOException

Deprecated.

Renders a single attribute. Default implementation does nothing if the value is null; otherwise, uses the current output method to render an attribute.

Parameters:

context - the rendering context

name - the attribute name for rendering

value - the attribute value

Throws:

java.io.IOException

renderAttribute

protected final void renderAttribute(UIXRenderingContext context,
                                     UINode node,
                                     java.lang.String name,
                                     AttributeKey valueKey)
                              throws java.io.IOException

Deprecated.

Renders a single attribute, getting the value from the UINode.

Parameters:

context - the rendering context

node - the node to get the attribute from

name - the attribute name for rendering

valueKey - the key to use to retrieve the attribute

Throws:

java.io.IOException

renderAttribute

protected final void renderAttribute(UIXRenderingContext context,
                                     UINode node,
                                     java.lang.String name,
                                     AttributeKey valueKey,
                                     java.lang.Object defaultValue)
                              throws java.io.IOException

Deprecated.

Renders a single attribute, getting the value from the UINode, and substituting a default value if the node doesn't have that attribute set.

Parameters:

context - the rendering context

node - the node to get the attribute from

name - the attribute name for rendering

valueKey - the key to use to retrieve the attribute

defaultValue - the default value to use if the attribute isn't set

Throws:

java.io.IOException

renderAttribute

protected final void renderAttribute(UIXRenderingContext context,
                                     UINode node,
                                     AttributeKey key,
                                     java.lang.Object defaultValue)
                              throws java.io.IOException

Deprecated.

Renders a single attribute, getting the value from the UINode, and substituting a default value if the node doesn't have that attribute set. This convenience method will use the same name for rendering the attribute as for retrieving it from the UINode.

Parameters:

context - the rendering context

node - the node to get the attribute from

key - the attribute key for rendering and for retrieving the value

defaultValue - the default value to use if the attribute isn't set

Throws:

java.io.IOException

getElementName

protected java.lang.String getElementName(UIXRenderingContext context,
                                          UINode node)

Deprecated.

Called to retrieve the element name to render. Default implementation returns null.

Parameters:

context - the rendering context

node - the current node
