Author:

kevinr Example of a custom JSF renderer. This demonstrates how to encode/decode a set of input field params that we use to generate a Date object. This object is held in our component and the renderer will output it to the page.

Method Detail

decode

public void decode(FacesContext context,
                   UIComponent component)

Overrides:

decode in class Renderer

See Also:

The decode method takes the parameters from the external requests, finds the ones revelant to this component and decodes the results into an object known as the "submitted value".

getConvertedValue

public Object getConvertedValue(FacesContext context,
                                UIComponent component,
                                Object val)
                         throws ConverterException

Overrides:

getConvertedValue in class Renderer

Throws:

ConverterException

See Also:

In the Process Validations phase, this method is called to convert the values to the datatype as required by the component. It is possible at this point that a custom Converter instance will be used - this is why we have not yet converted the values to a data type.

encodeBegin

public void encodeBegin(FacesContext context,
                        UIComponent component)
                 throws IOException

Overrides:

encodeBegin in class Renderer

Throws:

IOException

See Also:

All rendering logic for this component is implemented here. A renderer for an input component must render the submitted value if it's set, and use the local value only if there is no submitted value.
