Method Detail

performSelector

public final <A> void performSelector(NSSelector<A> selector,
                                      A arg,
                                      double delay)

Applies the specified method to this object using delay.

Type Parameters:

A - argument type

Parameters:

selector - Defines which method to apply.

arg - The argument of the method that is applied. NULL if the method has no arguments.

delay - The minimum time before which the message is sent.

performSelectorOnMainThread

public final <A> void performSelectorOnMainThread(NSSelector<A> selector,
                                                  A arg,
                                                  boolean waitUntilDone)

Applies the specified method to this object with the option of suspending the thread.

Type Parameters:

A - The type of the argument

Parameters:

selector - Defines which method to apply.

arg - The argument of the method that is applied. NULL if the method has no arguments.

waitUntilDone - TRUE then the current thread waits until the method is applied.

retain

public final NSObject retain()

Sends the retain message to this object.(Objective-C's feature)

Returns:

Returns this object after sending to it the retain message.

release

public final void release()

setValueForKey

public void setValueForKey(Object value,
                           String key)

Sets the value of the property specified by the key to the specified value.

Parameters:

value - The value to set on the property.

key - The name of the property whose value you want to retrieve.

setValueForUndefinedKey

public void setValueForUndefinedKey(Object value,
                                    String key)

valueForKey

Returns the id value of the specified key.

Parameters:

key - The key name of the value to be retrieved.

Returns:

The id value of the specified key.

valueForUndefinedKey
