getAsObject

public Object getAsObject(FacesContext context,
                 UIComponent component,
                 String value)

Description copied from interface: Converter

Convert the specified string value, which is associated with the specified UIComponent, into a model data object that is appropriate for being stored during the Apply Request Values phase of the request processing lifecycle.

Specified by:

getAsObject in interface Converter

Parameters:

context - FacesContext for the request being processed

component - UIComponent with which this model object value is associated

value - String value to be converted (may be null)

Returns:

null if the value to convert is null, otherwise the result of the conversion

Throws:

ConverterException - if conversion cannot be successfully performed

NullPointerException - if context or component is null

                 UIComponent component,
                 Object value)

Description copied from interface: Converter

Convert the specified model object value, which is associated with the specified UIComponent, into a String that is suitable for being included in the response generated during the Render Response phase of the request processing lifeycle.

Specified by:

getAsString in interface Converter

Parameters:

context - FacesContext for the request being processed

component - UIComponent with which this model object value is associated

value - Model object value to be converted (may be null)

Returns:

a zero-length String if value is null, otherwise the result of the conversion
