Method Detail

getClientId

public abstract java.lang.String getClientId()

Returns the client id for the client-side component instance. Renderer authors can use this API to retrieve the cached client id value. Note that this method will not necessarily return a non-null value: when a ClientComponent is of type SKIP, this will be null. As a result, clients should use the RichRenderer convenience method to get the client ID, and never call this directly.

addProperty

public abstract void addProperty(org.apache.myfaces.trinidad.bean.PropertyKey propertyKey,
                                 java.lang.Object propertyValue)
                          throws java.io.IOException

Adds the specified property name and a value to the set of properties that will be sent to the client for this ClientComponent. If the property does not need to be sent to the client - in particular, if there is an optimized getter that derived the attribute from the generated DOM - do not call addProperty().

Throws:

java.io.IOException

isActive

public abstract boolean isActive()

Returns true if this client component will, at this point, be sent to the client, or false if it will not be.

isNull

public boolean isNull()

Returns true if this client component will not become active at any time.
