Method Detail

encode

public elemental.json.JsonValue encode(java.lang.Number value)

Description copied from interface: Renderer

Encodes the given value into a JsonValue.

Specified by:

encode in interface Renderer<java.lang.Number>

Overrides:

encode in class AbstractRenderer<java.lang.Object,java.lang.Number>

Parameters:

value - the value to encode

Returns:

a JSON representation of the given value

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getNullRepresentation

public java.lang.String getNullRepresentation()

Description copied from class: AbstractRenderer

Null representation for the renderer.

Overrides:

getNullRepresentation in class AbstractRenderer<java.lang.Object,java.lang.Number>

Returns:

a textual representation of null

getState

protected com.vaadin.shared.ui.grid.renderers.NumberRendererState getState()

Description copied from class: AbstractClientConnector

Returns the shared state for this connector. The shared state object is shared between the server connector and the client connector. Changes are only communicated from the server to the client and not in the other direction.

As a side effect, marks the connector dirty so any changes done to the state will be sent to the client. Use getState(false) to avoid marking the connector as dirty.

Overrides:

getState in class AbstractRenderer<java.lang.Object,java.lang.Number>

Returns:

The shared state for this connector. Never null.

getState

protected com.vaadin.shared.ui.grid.renderers.NumberRendererState getState(boolean markAsDirty)

Description copied from class: AbstractClientConnector

Returns the shared state for this connector.

Overrides:

getState in class AbstractRenderer<java.lang.Object,java.lang.Number>

Parameters:

markAsDirty - true if the connector should automatically be marked dirty, false otherwise

Returns:

The shared state for this connector. Never null.
