public class AmfView
extends AbstractView

Spring-MVC View that renders AMF content by serializing the model for the current request using BlazeDS's AMF serialization/deserialization APIs.

By default, the entire contents of the model map (with the exception of framework-specific classes) will be encoded as AMF. For cases where the contents of the map need to be filtered, users may specify a specific set of model attributes to encode via the renderedAttributes property.

Method Detail

getRenderedAttributes

public Set<String> getRenderedAttributes()

Returns the attributes in the model that should be rendered by this view.

setRenderedAttributes

public void setRenderedAttributes(Set<String> renderedAttributes)

Sets the attributes in the model that should be rendered by this view. When set, all other model attributes will be ignored.

setDisableCaching

public void setDisableCaching(boolean disableCaching)

Disables caching of the generated AMF response.

Default is true, which will prevent the client from caching the generated AMF response.

prepareResponse

protected void prepareResponse(javax.servlet.http.HttpServletRequest request,
                               javax.servlet.http.HttpServletResponse response)

Overrides:

prepareResponse in class AbstractView

renderMergedOutputModel

protected void renderMergedOutputModel(Map<String,Object> model,
                                       javax.servlet.http.HttpServletRequest request,
                                       javax.servlet.http.HttpServletResponse response)
                                throws Exception

Specified by:

renderMergedOutputModel in class AbstractView

Throws:

Exception

filterModel

protected Object filterModel(Map<String,Object> model)

Filters out undesired attributes from the given model. The return value can be either another Map, or a single value object. If only a single attribute is present in the model map, that value will be returned instead of the full map.

Default implementation removes BindingResult instances and entries not included in the renderedAttributes property.

Parameters:

model - the model, as passed on to renderMergedOutputModel(java.util.Map, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)

Returns:

the object to be rendered
