Type Parameters:
T- the type this renderer knows how to presentAll Implemented Interfaces:
MethodEventSource, ClientConnector, Extension, Connector, Renderer<T>, Serializable
Direct Known Subclasses:
AbstractJavaScriptRenderer, ClickableRenderer, DateRenderer, HtmlRenderer, NumberRenderer, ProgressBarRenderer, TextRenderer
Enclosing class:
public abstract static class Grid.AbstractRenderer<T> extends Grid.AbstractGridExtension implements Renderer<T>An abstract base class for server-side
Grid renderers. This class currently extends the AbstractExtension superclass, but this fact should be regarded as an implementation detail and subject to change in a future major or minor Vaadin revision.See Also:

getSupportedParentType
@Deprecated protected Class<Grid> getSupportedParentType()Deprecated.
This method is inherited from AbstractExtension but should never be called directly with an AbstractRenderer.
Overrides:
getSupportedParentTypein classAbstractExtensionReturns:
a type that the parent must be an instance of
-
extend
@Deprecated protected void extend(AbstractClientConnector target)Deprecated.
This method is inherited from AbstractExtension but should never be called directly with an AbstractRenderer.
Overrides:
extendin classGrid.AbstractGridExtensionParameters:
target- the connector to attach this extension to
-
getPresentationType
public Class<T> getPresentationType()Description copied from interface:
RendererReturns the class literal corresponding to the presentation type T.
Specified by:
getPresentationTypein interfaceRenderer<T>Returns:
the class literal of T
-
encode
public JsonValue encode(T value)Description copied from interface:
RendererEncodes the given value into a
JsonValue.
-
getNullRepresentation
protected String getNullRepresentation()Null representation for the renderer
Returns:
a textual representation of
null
-
encode
protected <U> JsonValue encode(U value, Class<U> type)Encodes the given value to JSON.
This is a helper method that can be invoked by an
encode(T)override if serializing a value of type other thanthe presentation typeis desired. For instance, aRenderer<Date>could first turn a date value into a formatted string and returnencode(dateString, String.class).Parameters:
value- the value to be encodedtype- the type of the valueReturns:
a JSON representation of the given value
-
encodeValue
public static <T> JsonValue encodeValue(Object modelValue, Renderer<T> renderer, Converter<?,?> converter, Locale locale)Converts and encodes the given data model property value using the given converter and renderer. This method is public only for testing purposes.
Parameters:
renderer- the renderer to useconverter- the converter to usemodelValue- the value to convert and encodelocale- the locale to use in conversionReturns:
an encoded value ready to be sent to the client
