Constructor Detail

Method

protected Method(CClass cclass)

Constructs a method instance. If a subclass uses this method to construct a method, it must then invoke the init() to initialize method arguments/return.

Parameters:

cclass - objective-c class

Method

public Method(CClass cclass,
              Sel sel,
              com.jniwrapper.Parameter[] params,
              com.jniwrapper.Parameter retVal)

Constructs a method instance.

Parameters:

cclass - objective-c class

sel - selector to original method

params - method function arguments

retVal - method function return value

Method Detail

init

protected final void init(Sel sel,
                          com.jniwrapper.Parameter[] params,
                          com.jniwrapper.Parameter retVal)

Initializes method parameters.

Parameters:

sel - selector to method

params - callback function arguments

retVal - callback function return value

getId

protected Id getId()

getSel

protected Sel getSel()

register

public void register()

Override method implementation

unregister

public void unregister()

Restore the original method implementation

invokeOriginal

protected final void invokeOriginal(com.jniwrapper.Parameter returnValue,
                                    com.jniwrapper.Parameter[] parameters)
                             throws com.jniwrapper.FunctionExecutionException

Invokes the original class method with the passed parameters. A type of the return value and parameter types should correspond to types of the native code function.

Parameters:

returnValue - reference to return value

parameters - array of parameters of called function

Throws:

com.jniwrapper.FunctionExecutionException
