public class FileRenderer
extends BaseManagedRenderer

When maintained by a `RenderManager`, a `FileRenderer` renders a single page's contents from a static file.

The properties `contentType`, `pageExpires`, `charSet` may be set at page level or defaulted at `RenderManager` level. However the page name must be set at page level via a call to ``setName(String)`` or by use of the `<name>` `provider.xml` tag.

Field Summary
`static int` | `CHAR_BUFFER_SIZE`

Constructor Summary
`FileRenderer()` Null Constructor.
`FileRenderer(RenderManager parent, java.lang.String pageName)` Creates and initializes a `FileRenderer` owned by the given `RenderManager`, describing a page with the given name.

Method Summary
`java.lang.String` | `getAppRoot()` Gets the root physical path for the renderer's pages.
`java.lang.String` | `getCharSet()` Gets the Default IANA character encoding to be used for this renderer's pages.
`java.lang.String` | `getName()` Gets the name of the page described by this `Page`.
`void` | `renderBody(PortletRenderRequest pr)` Render the specified page's contents using the current appRoot and page name.
`void` | `setAppRoot(java.lang.String path)` Sets the root physical path for the renderer's pages.
`void` | `setCharSet(java.lang.String charSet)` Sets the Default IANA character encoding to be used for this renderer's pages.
`void` | `setName(java.lang.String pageName)` Sets the name of the page described by this `Page`.
`void` | `validate(java.lang.String context, ValidationError errors)` Validates the internal state of this `FileRenderer` instance.

Field Detail

### CHAR_BUFFER_SIZE

    public static final int CHAR_BUFFER_SIZE

See Also:
  Constant Field Values

Constructor Detail

### FileRenderer

    public FileRenderer()

  Null Constructor. The `BaseManagedRenderer.preInitialize(Object)` method should be called after creating an object with this constructor and the `BaseManagedRenderer.postInitialize()` method should be called after setting up page properties with the various accessor methods. Normally a `DefaultNodeHandler` takes care of these details.

### FileRenderer

    public FileRenderer(RenderManager parent,
                        java.lang.String pageName)
                 throws PortletException

  Creates and initializes a `FileRenderer` owned by the given `RenderManager`, describing a page with the given name.

Parameters:
  `parent` - the `RenderManager` that owns this page
  `pageName` - the `appPath` relative name of the renderer's page
Throws:
  `PortletException` - if an error occurs while initializing the object

Method Detail

### setName

    public void setName(java.lang.String pageName)

  Sets the name of the page described by this `Page`.

  Parameters:
    `pageName` - `appRoot` relative name of the page

### getName

    public java.lang.String getName()

  Gets the name of the page described by this `Page`.

  Returns:
    `appRoot` relative name of the page

### setAppRoot

    public void setAppRoot(java.lang.String path)

  Sets the root physical path for the renderer's pages.

  Parameters:
    `path` - the root physical path for the renderer's pages.

### getAppRoot

    public java.lang.String getAppRoot()

  Gets the root physical path for the renderer's pages.

  Returns:
    the root physical path for the renderer's pages.

### setCharSet

    public void setCharSet(java.lang.String charSet)

  Sets the Default IANA character encoding to be used for this renderer's pages.

  Parameters:
    `charSet` - IANA character encoding to be used for this renderer's pages

### getCharSet

    public java.lang.String getCharSet()

  Gets the Default IANA character encoding to be used for this renderer's pages. If a character encoding hasn't been set explicitly on this `BaseManagedRenderer`, then the value returned by calling the `RenderManager.getCharSet()` method on the parent `RenderManager` is returned.

  Returns:
    IANA character encoding to be used for this renderer's pages

### renderBody

    public void renderBody(PortletRenderRequest pr)
                    throws PortletException

  Render the specified page's contents using the current appRoot and page name. File Renderer does this by copying the contents of the static file to the output stream.

  Specified by:
    `renderBody` in class `ManagedRenderer`
  Parameters:
    `pr` - a PortletRenderRequest
  Throws:
    `PortletException` - if an error occurs while rendering.

### validate

    public void validate(java.lang.String context,
                         ValidationError errors)

  Validates the internal state of this `FileRenderer` instance. Errors found are reported using the supplied `ValidationError` instance.

  Specified by:
    `validate` in interface `Validateable`
  Overrides:
    `validate` in class `BaseManagedRenderer`
  Parameters:
    `context` - The context of the calling instance.
    `errors` - The current list of errors.
