      extended by org.zkoss.zk.au.out.AuInvoke

public class AuInvoke
extends AuResponse

A response to ask the client to invoke a function. Unlike AuScript, it invokes the given function (rather than evaluates a JavaScript snippet).

There are basically two approaches. First, AuInvoke(Component, String, Object...) is used to invoke the method of the peer widget of the given component. Second, AuInvoke(String, Object...) is used to invoke a global function (at the client).

data[0]: the component
data[1]: the client function name (i.e., JavaScript function)
data[2]: the second argument
data[3]: the third argument...

Note: the first argument is always the component itself.

Constructor Detail

AuInvoke

public AuInvoke(Component comp,
                java.lang.String function)
Construct AuInvoke to call the peer widget's member function with no argument.

Parameters:
comp - the component that the widget is associated with. It cannot be null.
function - the function name

AuInvoke

public AuInvoke(Component comp,
                java.lang.String function,
                java.lang.Object arg)
Construct AuInvoke to call the peer widget's member function with one argument.

Notice that if you want to pass an array-type argument, you have to cast it to Object as follows:
new AuInvoke(comp, "setOverride", (Object)new Object[] {"a", "b"}).
Otherwise, the third argument will be handled by AuInvoke(Component, String, Object[]), and then considered as an array of arguments (rather than an argument with an array-type value.

Parameters:
comp - the component that the widget is associated with. It cannot be null.
function - the function name
arg - the additional argument. It could be null, String, Date, DeferredValue, and any kind of objects that the client accepts (marshaled by JSON).
Since:
5.0.0

AuInvoke

public AuInvoke(Component comp,
                java.lang.String function,
                boolean arg)
Construct AuInvoke to call the peer widget's member function with one boolean argument.

Parameters:
comp - the component that the widget is associated with. It cannot be null.
function - the function name
arg - the additional argument. Different devices might support more types.
Since:
5.0.0

AuInvoke

public AuInvoke(Component comp,
                java.lang.String function,
                int arg)

Parameters:
comp - the component that the widget is associated with. It cannot be null.
function - the function name
arg - the additional argument.
Since:
5.0.0

AuInvoke

public AuInvoke(Component comp,
                java.lang.String function,

                java.lang.Object arg2)
Construct AuInvoke to call the peer widget's member function with two arguments.

Parameters:
comp - the component that the widget is associated with. It cannot be null.
function - the function name
arg1 - the additional argument. It could be null, String, Date, DeferredValue, and any kind of objects that the client accepts (marshaled by JSON).
